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



  • 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
