Performance Features
- High gloss of the coating film, good transparency.
- High construction solid content, good workability.
- Can be used for pigment grinding, excellent mechanical stability.
- Excellent flexibility
Applications
- Mainly used for the preparation of amino stoving paint,
- Solid color paint, flash paint used in steel drums, wheel hubs, bicycles and electric vehicles and other industries
- Stoving paints for generally industrial coatings and coil coatings.
Application Guide
◆ After it is neutralized with N, N-dimethylethanolamine( 5~6% of the resin), it can be directly diluted with water.
◆ Add methylated amino resin (20%-30% of the resin) for baking and curing. The baking temperature is above 120°C. The baking conditions and paint film properties are related to the amino resin used. When it used with the fully methylated amino resin, an acid catalyst(0.5-1% of the resin) must be added, and the baking temperature must be above 140°C.
◆ It is a water-dilutable saturated polyester resin, which can be infinitely diluted with deionized water.
◆ The pH value can be adjusted with organic amine or ammonia water, and the viscosity of the emulsion will increase with the increase in pH value.
