High Solids Low Viscosity Hydroxyl Acrylic Resin
SE6893 is a two-component hydroxyl acrylic resin, it has high solid
content, low viscosity, high strength, fast drying, good weather
resistance and other characteristics, due to the use of low
molecular weight resin, the coating viscosity is greatly reduced,
and because of the high solid content, thus reducing the content of
organic compounds in the coating. It is a new kind of resin which
has both performance and environmental protection. Therefore
initiatR SE6893 is an environmentally friendly solvent based hydroxyl
acrylic resin.
Recommended applications: automobile refinishing paint, plane
coating, traffic paint, floor paint.
