Poly poxy coatings presentation

  1. 1. Presenters: Mr Simon KuekMr Sures as assistant to Mr Simon 1
  2. 2. COMPANY PROFILE Incorporated on 3rd November 1987 Based in Nilai, Malaysia Specializes in Superior Quality Lacquers, Solvent and Water-based Coatings. Possesses the manufacturing ability and technical knowledge of producing furniture paints and lacquers, having instilled western technologies in the production process. An expert in manufacturing a wide range of coating products A supplier to the local market and exporter to Vietnam, Thailand and India. 2
  3. 3. Coatings Substracts Vehicle Machineries M.D.F Application Lacquer H.D.F equipment Make sure the substracts in well prepare Lacquer must be well mix with proper thinner and check viscosity , when hardener in use, make sure its well mix and be sure of pot-life Make sure the application equipment is properly clean and right nozzle of spray gun and output of lacquer paints be adjusted. 3
  4. 4. General Forest Stewardship Council Woodveneer used by Furniture Factor y Birch Beech Pine Rubber wood White Oak Alder Aspen Cherry Walnut Acacia Eucalyptus European Oak 4
  5. 5. SANDING & PROFILING Sanding machine 3 belt: 170, 180, 240 Orbiter sanding machine 170, 180, 240, 320, 400, 600, 1500 Brush sander Dumpling sanding Auto sanding for edges R2, R3, edges CNC rounder (Profiling machine) 5
  6. 6. M.D.F PROBLEM E 2, E1, E 05, E0 Emission  Uneven sanding cause surface of formaldehyde to look weave on high gloss Pentachlorophenol chemical finishing Glue content formaldehyde  Swelling on veneer (industrial flour  Porosity on edges after profile water urea formaldehyde (high absorption of lacquer.) glue)  Paper lamination easily over Thickness of veneer sand when after lacquering. Gap of veneer joint  PVC vacuum an M.D.F board Delaminating of veneer (Proper glue to be used) Glue not resistance to  Migration of stain from pine solvent (cause pregnant) wood fiber M.D.F when white Edges delaminate cause by painting is applied. uneven glue spread or too  Rubber spot too many low viscosity  Too high humidity  Too high moisture content. 6

  12. 12. Terms use in mixture1. Single pack: just dilute with thinner2. Ready to use: just spray (RTU)3. Atmosphere cure or self crosslink : react with oxygen and crosslink4. Two pack : part A & part B (hardener pot-life applied PU, NC)5. Three pack : part A (lacquer); B (mek peroxide); C (cobalt-diluene strene monomer)6. U.V cure by UV lamp7. Open grain and full grain cover; semi open grain. 12
  13. 13. Recommended viscosity for different application Viscosity (hand spray recommended) 12 second to 13 second (Ford cup 4) ; Viscosity airless spray – 18 second (Ford cup 4) Viscosity curtain coater & rainbow – 33 second (Ford cup 4) Disk electrostatic – 9 second Roller coater – 2 minute Dipping – 10 second 13
  14. 14. Thinner is very important1. To achieve better dilution.2. Too slow drying cause stacking problem. Too fast drying causing flow problem.3. Good electrostatic charge4. Blushing5. Orange peel6. Fast dry (pin hole) in two pack system7. Using recycle thinner may cause many problem Mixture of different kind of coatings in inter coat  PU sealer & NC top (ok)  NC sealer & PU top (not allow)  AC sealer & PU top (not allow)  PU sealer & AC top (not allow)  PE sealer & PU top (ok)  UV sealer & PU top (ok) 14
