    22. 24. Epoxy Resin Epoxy resin tops and sinks are produced from a composite of epoxy resin, silica, inert fillers, and organic hardeners. Material is cast and cured in ovens at elevated temperatures. Epoxy resin is homogeneous throughout and non-absorbent. Material Options
    23. 25. Solid Surface Solid Surface work tops are produced by combining unsaturated polyester resin with a combination of fillers, pigments and catalysts/or polyester resin, free from internal strengthening fibers and pigment. The resulting product is homogenous throughout, renewable, and non-porous. An invisible seam is the most well known feature of Solid Surface. Material Options
    24. 26. Stainless Steel <ul><li>Stainless steel tops and sinks are usually fabricated from 14 to 18 gauge type 304 or 316 series stainless steel. Surfaces are integrally formed with all seams fully welded with stainless steel fillers, ground smooth, and blended to a #4 mill finish (solder or compounded fillers not acceptable). </li></ul>Material Options
    25. 27. High Pressure Laminate <ul><ul><li>High pressure plastic laminate tops are made from melamine-impregnated surface papers pressed over phenolic-impregnated craft paper layers. The back is sanded to facilitate bonding to the top of suitable substrates. Laminate tops are available in a variety of colors. </li></ul></ul>Material Options
    26. 28. Composite Resin <ul><li>Composite resin (or phenolic resin) work surfaces are very similar to high pressure plastic laminates with the exception that craft paper backers are saturated with phenolic resin and built up to a finished thickness. Surface resins may vary according to product, intended application, or manufacturer. </li></ul>Material Options
    27. 29. Resin Impregnated Stone <ul><li>Impregnated natural sand stone tops are produced from stone, free of veins or seams and impregnated with a resin. Additional surface coatings are baked at a high temperature to polymerize the resins and harden the stone. </li></ul>Material Options
    28. 30. Material Performance <ul><li>How do the Materials Compare in Performance? </li></ul><ul><li>An in-Depth look at: </li></ul><ul><li>Physical Durability </li></ul><ul><li>Chemical Resistance </li></ul><ul><li>Heat Resistance </li></ul><ul><li>Moisture Resistance </li></ul><ul><li>Flammability </li></ul><ul><li>Useful Life </li></ul>
    29. 31. Physical Durability Material Performance
    30. 32. <ul><li>This refers to the ability of a material to withstand not only the wear of normal use, but also withstand attempts to misuse or deface countertops using sharp objects such as: ink pens, pencils, scissors, screw drivers, knives, etc. </li></ul><ul><li>The durability of a work surface is often related to how monolithic a material is. A monolithic countertop is one in which consists of the same material throughout its entire thickness. </li></ul><ul><li>Materials which are non-monolithic (i.e. those which are manufactured by a lamination process) may exhibit a tendency to be easily pried apart and may de-laminate over time if abused or subjected to moisture. </li></ul>Physical Durability Material Performance
    31. 33. Comparative Monolithic Properties Material Performance Laminated Surface Monolithic Surface A monolithic countertop is one in which consists of the same material throughout its entire thickness. No High Pressure Laminate Yes Epoxy Resin Yes Stainless Steel No Resin Impregnated Stone No Composite Resin Yes Solid Surface Monolithic Material
    32. 34. Chemical Resistance Material Performance
    33. 35. <ul><li>The chemical resistance of a material is measured by performing tests which determine how well it withstands sustained exposure to a wide array of acids, alkalies (or bases) and solvents. </li></ul><ul><li>After exposure for a 24 hour period, the countertop material is rated on a scale from 1 to 5 (1 – being equivalent to “No Effect” or no detectable change in the material surface and 5 – being equivalent to “Failure” or pitting/erosion of the work surface material; obvious and significant deterioration). </li></ul>Chemical Resistance Material Performance
    34. 36. Comparative Chemical Resistance Material Performance Yes No Yes High Pressure Laminate Yes No No Solid Surface Yes Yes No Stainless Steel Solvent Base Acid Material Yes Yes Yes Resin Impregnated Stone Yes Yes Yes Composite Resin Yes Yes Yes Epoxy Resin
    35. 37. Heat Resistance <ul><li>The heat resistance of a countertop material refers to its ability to perform after withstanding high temperatures. Two different tests are used to assess the material’s susceptibility to high heat conditions: </li></ul>Material Performance a. First, a porcelain crucible, heated to a dull red color is placed on the specimen and allowed to cool to ambient temperature. If there are no resulting cracks or blisters, the outcome is considered good. Some slight dulling or color change in the material is acceptable and still considered to be a good result.
    36. 38. Heat Resistance <ul><li>b. Secondly, in a procedure commonly called the Bunsen Burner Test, a 3/8” Bunsen burner is adjusted to a quite flame with a 1-1/2” inner blue cone and then overturned on the test material, exposing it to the flame for 5 minutes. If there are no resulting blisters or cracks on the work surface, the outcome is considered good. </li></ul>Material Performance
    37. 39. Comparative Heat Resistance Material Performance Bad Bad High Pressure Laminate Good Good Epoxy Resin Good Good Stainless Steel Good Good Resin Impregnated Stone Bad Bad Composite Resin Bad Bad Solid Surface Bunsen Burner Hot Crucible Material Heat Blister Not Compromised
    38. 40. Moisture Resistance <ul><ul><li>A countertop’s resistance to the effects of moisture is usually related to its water absorption as measured under the controlled testing conditions of ASTM D570. Monolithic materials tend to have greater resistance to the effects of prolonged exposure to liquids. The three most serious problems associated with the use of absorbent materials in laboratory environments are: </li></ul></ul><ul><ul><li>De-lamination - Swelling - Warping </li></ul></ul>Material Performance Laminate Monolithic Surface
    39. 41. <ul><li>Low moisture resistance leads to de-lamination, swelling and warping. </li></ul>Comparative Moisture Resistance Material Performance No High Pressure Laminate Yes Epoxy Resin Yes Stainless Steel No Resin Impregnated Stone Yes Composite Resin No Solid Surface Moisture Resistant Material
    40. 42. Flammability <ul><li>Tests have shown that US epoxy resin worksurfaces are self extinguishing. This adds to the safety of the lab environment if accidents occur. </li></ul>Material Performance Fume Hoods After A Fire
    41. 43. Useful Life <ul><li>With good housekeeping practices and proper maintenance, epoxy resin worksurfaces should remain functional for the useful life of the lab. </li></ul>Material Performance

    43. 45. Material Thickness <ul><li>Epoxy Resin is normally manufactured in one of three thicknesses: ¾”, 1” or 1 ¼”. Tops of 1” are the industry standard. </li></ul>Design Options
    44. 46. Solid Colored Epoxy <ul><li>Epoxy resin can be produced in an array of colors. The most common and traditional color is black . Other available colors include: white , green and gray . Some manufacturer offer custom color options. As in any industry, custom colors add to lead times and expense. For example, white can cost up to 30% more than black. </li></ul>Design Options
    45. 47. Granite Filled Epoxy <ul><li>These epoxy tops incorporate granite aggregate and are produced in colors gray and red . </li></ul>Design Options
    46. 48. Edge Styles <ul><li>There are two basic epoxy resin edge styles: </li></ul><ul><ul><li>Machined edge tops are available with either 3/16” radius or 1/8” beveled edge. Machined edge tops are available with a Drip Groove (a groove cut along the underside edge to prevent liquid from flowing back to the cabinet). </li></ul></ul><ul><ul><li>Molded edge tops have molded radius. The dimension of its radius varies by manufacturer. </li></ul></ul>Design Options 1/8” Machined Bevel 3/16” Machined Radius Molded Radius
    47. 49. Surface Types <ul><li>There are three basic epoxy resin surface types: Flat Tops, Marine Tops and Fume Hood Bases. </li></ul>Design Options
    48. 50. <ul><li>Flat Tops maximize workspace and can be based in conjunction with any of the three edge profiles. </li></ul>Surface Types Design Options
    49. 51. Surface Types <ul><ul><li>Marine Tops have a raised liquid containment rim around their perimeter and are designed for use in wet areas. The rim is integrally molded wherever possible. If the room’s layout precludes the use of molded pieces, the raised edges are applied or cut and seamed to the top. </li></ul></ul>Design Options * 1.25” [32mm] also available 1/4” Dish 1 inch 1/4” Dish 1/4” Dish
    50. 52. Surface Types <ul><ul><li>Fume Hood Bases are molded in a variety of sizes to fit most fume hood cabinets. They have a built-in 3/8” deep liquid containment area. </li></ul></ul>Design Options
    51. 53. Curb Types <ul><li>There are two types of curbs (backsplashes): </li></ul><ul><ul><li>Loose Curbs are fabricated and shipped “loose” for installation in the field. The top edge of loose curbs can be finished with a 1/8” machined bevel, a 3/16” machined radius or a 1/2” molded radius. </li></ul></ul>Design Options
    52. 54. Curb Types <ul><ul><li>Integral (Coved) Curbs are specialty surfaces cast using “L” shaped molds to eliminate seams between the surface and the backsplash. Integral curbs are 1” thick at the work surface and taper to ¾” at the top edge. Since jobsite wall tolerances are difficult to maintain, these types of curbs are generally recommended only when minimizing joints is of highest priority. </li></ul></ul>Design Options
    53. 55. Sink Types <ul><li>There are two types of epoxy resin sinks: </li></ul><ul><ul><li>Drop-In Sinks feature basins supported by the countertop and require no under sink support. Standard installation requires a beveled rabbet cut through the worksurface so that the sink rim rests on the lip of the cutout. </li></ul></ul>Design Options
    54. 56. Sink Types <ul><ul><li>Undermount Sinks are mounted below the countertop surface requiring support, (supplied by the casework manufacturer). The required under-sink support often limits the amount of usable cabinet space; so, these sinks are seldom used today. </li></ul></ul>Design Options
    55. 57. Sink Types <ul><li>Drop-In sinks are available in ADA models which have an inside depth of 5”. Graduated or Step-Sinks are also available. These sinks have an inside depth of 5” which steps-down to 11”. </li></ul>Design Options
    56. 58. Drain Grooves or DrainTops <ul><ul><li>When a work surface is used in a sink (wet) area, there is the option of providing drain grooves in the work top to drain liquids towards the sink. These grooves may either be cut into the surface during manufacturing or molded into the surface in the form of raised ribs. Molded drain tops perform better than those with machine routed grooves. </li></ul></ul>Design Options
    57. 59. Epoxy Resin Accessories <ul><li>Accessories are also available in Epoxy Resin such as: </li></ul><ul><li>- Troughs </li></ul><ul><li>- Cup sinks (waste funnels) </li></ul><ul><li>- Sink overflows </li></ul><ul><li>- Peg boards. </li></ul><ul><li>Black polypropylene sink outlets, overflows, and cup sinks are typically supplied unless a color is specified. </li></ul>Design Options
    58. 60. Design Standards <ul><li>Countertop Overhang </li></ul><ul><li>Countertop Size </li></ul><ul><li>Location of Sinks </li></ul><ul><li>Curb Height </li></ul><ul><li>What are the basic design standards for Epoxy Resin? </li></ul>
    59. 61. Countertop Overhang <ul><ul><li>Standard laboratory countertop overhang is 1”. Drip grooves underneath the top are optional and should be specified if desired. </li></ul></ul>Design Standards
    60. 62. Countertop Sizes <ul><li>Counter tops should be as long as possible to minimize seams. Tops can be produced in lengths up to 96”. </li></ul><ul><li>Avoid placing seams in wet areas and knee spaces. </li></ul>Design Standards
    61. 63. Location of Sinks <ul><li>Drop-In sinks must be located at a minimum of 3.5” from the edges of the countertop. </li></ul><ul><li>Undermount sinks must be located at a minimum of 4.5” from the edges of a countertop. </li></ul>Design Standards
    62. 64. Curb Height <ul><li>The standard height for epoxy resin curbs, whether loose or integral (coved), is 4”. </li></ul><ul><li>Loose Curbs can be specified to any height. </li></ul><ul><li>Integral Curbs can be trimmed or custom molded to 6” or 8”. </li></ul>Design Standards
    63. 65. Installation Criteria <ul><li>Job Site Storage and Handling </li></ul><ul><li>Installation of Tops </li></ul><ul><li>Protection After Installation </li></ul><ul><li>What is the basic criteria for quality installation of Epoxy Resin tops? </li></ul>
    64. 66. Jobsite Storage and Handling <ul><li>When epoxy resin tops arrive at a jobsite they should always be stored laying flat in a safe place until ready for installation. Tops should never be stored leaning against walls as this could cause some work surface deflection. </li></ul>Good Not Good Installation Criteria
    65. 67. <ul><li>Tops should be scheduled to arrive at the jobsite just prior to installation and stored indoors. </li></ul><ul><li>They should also remain covered for surface protection. If the tops must be stored outside, they should be covered to prevent damage from the elements. </li></ul>Jobsite Storage and Handling Installation Criteria
    66. 68. Installation of Tops <ul><li>Epoxy resin tops require an experienced epoxy resin installer. </li></ul>Installation Criteria
    67. 69. <ul><li>Epoxy resin tops should be installed when temperatures in the space or room where they are to be installed are at least 77º Fahrenheit . The epoxy adhesive used to bond the tops may not cure properly when tops are installed when temperatures are outside of this norm. </li></ul>Installation of Tops Installation Criteria
    68. 70. <ul><li>The installer should insure that the tops are installed such that they are flat and level. </li></ul><ul><li>It is appropriate and expected that an installer will use shims and clamps to achieve a flat and level installation. </li></ul>Installation of Tops Installation Criteria
    69. 71. Installation of Tops <ul><li>The joints between epoxy resin pieces should be uniform throughout the job. Normal joint width should be between 1/8” and 1/16”. Tops should be dry fit prior to application of epoxy adhesive. </li></ul>Installation Criteria
    70. 72. Protection After Installation <ul><li>The surface of epoxy resin should be protected by covering the tops once they are installed. </li></ul>Installation Criteria
    71. 73. <ul><li>Workers from other trades should be instructed to not place tool boxes, tools or any hardware directly on the surface of the tops. Workers should also be instructed to not stand on the tops, but to use ladders or scaffolding instead. </li></ul>Protection After Installation Installation Criteria
    72. 74. Course Summary <ul><li>By now you should have a better understanding of the following: </li></ul><ul><li>The characteristic environments where industrial grade work surfaces are typically specified. </li></ul><ul><li>The characteristics and attributes of Epoxy Resin and be able to compare and contrast it with other materials such as: Solid Surface, Stainless Steel, Chemically Resistant Composite Resin, Chemically Resistant High Pressure Laminate, and Resin Impregnated Natural Stone. </li></ul>
