Recommendation of resin for wood coatings
- Advantages
- 1.It dries rapidly 2.The construction is simple 3.Its gloss is stable and unlikely to be influenced by environment
- Disadvantages
- 1.It doesn’t have adequate richness 2.It doesn’t have adequate hardness, and generally is of HB grade. 3.It doesn’t have solvent resistance剂
- Typical Technologies
- 1.NC bottom, NC surface 2.PU bottom, NC surface
- Construction Methods
- 1.Roller painting 2.Dipcoating 3.Spraying (manual spraying, electrostatic spraying, etc.)
- For wood coatings, recommendations are 3139, 3670, 3370D, 3370C and 2050, etc., satisfying demands of different varieties of paints
- Common Problems during Application
- Basically, all short oil alkyd resin and thermoplastic acrylic resin can be applied for nitro-lacquer; only that there will be difference in gloss, tenacity and other performances when being applied as undercoat, lusterless paint and varnish due to intrinsic difference in solvent, compatibility and viscosity. Brushing or blushing during spraying and brush painting can be solved by adjusting the solvent
