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.
Storage Condition
Store the product in a cool and dry place, the recommended storage
temperature is 0~40℃. The shelf life is one year. After the
expiration date, if the test passed, it still can be used.
