HELLO
ALL MEMBERS.
I HAVE DEVELOPED A BIO DEGRADABLE WATER REPELLENT AS WELL AS HEAT SEAL COATING. THIS IS WATER BORNE. THIS COATING IS MEANT FOR PAPER COATING , FOR MANY PACKAGING APPLICATIONS INCLUDING DIRECT FOOD CONTACT.IT REPLACES PLASTIC FILM COATING.THE COATED PAPER IS RECYCLABLE. THIS COATING IS EVEN MISCIBLE WITH PAPER PULP . THE BLENDED PAPER PULP , MOULDED PRODUCT EXHIBIT EXCELLENT WATER REPELLENT PROPERTIES.
I AM LOOKING FOR SOME HELP / ASSISTANCE IN APPLYING FOR USA FDA APPROVAL.
THIS IS A REQUEST TO ALL MEMBERS , TO GUIDE ME ON THE SAME. THANKS IN ADVANCE FOR YR TIME.
BEST REGARDS

Water Repellent Coating Applications

  1. 1. By Shrikant Athavale Prathith Consultants Pune India 124-07-2013
  2. 2. 224-07-2013 Product Details This is a Innovative Water Borne Coating , based on Pre Vulcanised Natural Rubber Latex / Synthetic Rubber latex , and Naturally occurring waxes ,with high performance, contains no plastic . It provides superior Water repellency, with very good barrier properties to moisture, oil , grease and fatty acids. This coating is useful on both virgin and recycled paper / fibre board. The coated paper is 100 % recyclable and Bio degradable. , Water Repellent coating ,is a eco-friendly alternative to LDPE
  3. 3. 324-07-2013 Overview This Water repellent coating ,is compounded using Pre Vulcanized Natural Rubber latex / Synthetic Rubber Latex ( SBR ) , Bee’s wax emulsion , and Soybean Wax Emulsion . It offer’s good Water repellency replacing the , usage of , plastics. This is 100% eco friendly. This is a Indian Patent Product
  4. 4. 424-07-2013 Application Water Repellent Paper for the Manufacture of 1.Corrugated Boxes 2.Paper bags 3.Soap Wrappers 4.Paper Cores 5.Paper Drums 6.Paper Pallets 7.Pulp molded products 8.Other Packaging Applications.
  5. 5. 524-07-2013 Application Water Repellent Coating Is useful as a Additive for the Manufacture of 1.Molded Tray’s 2.Molded Pallets 3.Molded Boxes for Industrial, food , Electronics and other packaging applications.
  6. 6. 624-07-2013 Application Methods Water Repellent , can be easily coated , 1. By Gravure , Gravure &Myer bar , Kiss Coating Method. Very low coat weights like 2-3 gm/ sq.mtr , provide excellent Water repellency 2. By Brush 3. By Spray Gun Or Can be Blended with The paper Pulp itself , to manufacture Molded Pulp products for Packaging
  7. 7. 724-07-2013 Coating Methods
  8. 8. 824-07-2013 Pulp Blending Paper Scrap Virgin Paper Pulp Add picture of paper pulp
  9. 9. 924-07-2013 Pulp Blending The process of paper recycling involves mixing Scrap paper with water and chemicals to break it down. It is then chopped and heated, to break it down into strands of cellulose, which is called pulp, or slurry. It is strained through screens, which remove any glue or plastic that may still be in the mixture then cleaned, de- inked, bleached, and mixed with water.
  10. 10. 1024-07-2013 Pulp Blending It is at this stage , mix our Water Repellent coating , approximately 5-10% of the pulp quantity . Then it can be made into new paper. This paper will exhibit excellent Water Repellent Properties.
  11. 11. 1124-07-2013 Paper Manufacture Now the regular procedures of paper manufacturing can be followed.
  12. 12. 1224-07-2013
  13. 13. 1324-07-2013 Recycling of paper Paper recycling is the process of turning waste paper into new paper products. There are three categories of paper that can be used as feed stocks for making recycled paper . Paper Scrap
  14. 14. 1424-07-2013 Recycling of paper There are three categories of paper that can be used as feed stocks for making recycled paper.  Mill broke  Pre-consumer waste and Post-consumer waste
  15. 15. 1524-07-2013 Recycling of paper  Mill broke, Mill broke is paper trimmings and other paper scrap from the manufacture of paper, and is recycled internally in a paper mill.  Pre-consumer waste Pre-consumer waste is material which left the paper mill but was discarded before it was ready for consumer use. and  Post-consumer waste Post-consumer waste is material discarded after consumer use, such as old corrugated containers (OCC), old magazines, old newspapers (ONP), office paper, old telephone directories, and residential mixed paper (RMP)
  16. 16. 1624-07-2013 Paper Recycling Process The process of paper recycling involves mixing used paper with water and chemicals to break it down. It is then chopped up and heated, which breaks it down further into strands of cellulose, a type of organic plant material; this resulting mixture is called pulp, or slurry. It is strained through screens, which remove any glue or plastic that may still be in the mixture then cleaned, de- inked, bleached, and mixed with water. At this stage the Water Repellent Coating additive can be blended. Then it can be made into new paper . The same fibres can be recycled about seven times, but they get shorter every time and eventually are strained out.
  17. 17. 1724-07-2013 Paper Recycling Saves 1. Energy It takes approximately 64% less energy to make paper from recycled materials ( used paper ) than from virgin fibre ( trees0. Recycling one ton of paper saves the equivalent of 70 gallons of gasoline or 3 barrels of oil. 2. Water It takes 61 % less water to make paper from 1005 recycled materials
  18. 18. 1824-07-2013 Paper Recycling Saves 3. Land Every ton of paper recycled saves 100 cubic feet of landfill space 4. Air Making recycled paper results in 70$ fewer air pollution than making paper from virgin wood. 5. Natural Resources ( Trees ) for every ton of paper recycled , approximately 17 trees are save
  19. 19. 1924-07-2013 Water Repellent Chemistry Water repellent or water proofing agents are generally of two forms Elastomeric coatings that adhere to the substrate and cure to form a flexible and protective layer Water repellent chemicals that penetrate deeply into the substrate and they bond with it.
  20. 20. 2024-07-2013 The mechanism of Water Repellency Repellent Permeable Our water Repellent coating is formulated in such a way that the surface tension of the same is suitably adjusted for easy wet out on the surface ( paper ) to be coated. This is why the paper exhibits superior water repellency. at the same time it does not penetrate into the pores , and hence it is breathable. Trapped Water vapour’s can easily slip through , however the water molecules are too large to penetrate.
  21. 21. 2124-07-2013 The mechanism of Water Repellency However our water repellent additive can be blended with the paper pulp and it wet out paper molecules more effectively and bonds them together hence the moulded pulp is 100% water proof , with very negligible water vapour transfer
  22. 22. 2224-07-2013 Advantages 1. This is ideal Replacement for Plastic coated paper 2. The Coated paper is Bio degradable , Recyclable 3. Excellent Coat ability on paper , 4. Good Gloss 5. Very Good Water Resistance 6. High Coating speeds 7. Lower Coating weight ( approx. 4-5 gm dry per sq. Mtr. ) 8. Cost effective by at least 15-20%
  23. 23. 2324-07-2013 Paper Water Repellency & Water Beading with our additive Consumer Grade Premium Grade Initial After 1 hour After 2 hours
  24. 24. 2424-07-2013 Our Water Repellent additive imparts greater water repellency and water beading We recommend a dosage of 5-7 % of Pulp for Consumer grade and 7-12% for Premium grade
  25. 25. 2524-07-2013 Our Water Repellent additive  provides greater water repellency.  it is available as an additive to recycled pulp or virgin pulp.  it produces great results as a alone coating on ready paper.
  26. 26. 2624-07-2013 Technical Information Our Water Repellent Additive is a low VOC, hydrophobic , non silicone water borne emulsion specifically designed to impart water repellency and beading on paper. It is miscible with paper pulp or can be applied on ready paper. Our water repellent produces a clear finish. it imparts pronounced and long lasting water beading. Typical Properties Appearance : White Liquid Solids contant : 30% pH : 7.5 Specific Gravity ( 25 oC) : 0.95 Volatile Organic Content : < 50 gm/L Characteristics Protects paper Excellent additive for pulp Water resistant Finish prevents water staining / wear Non Yellowing - hence assures colour stability Effective on porous and semi porous papers surface coated paper allows substrate to "Breathe" Recommendations The pH of our Water Repellent additive/ coating should never drop below 7.0 . Below 7.0 the additive could be instable Our additive withstands high shear , high speed mixing, high pressure flow through a small nozzle or filter , and will not precipitate that can cause instability
