Hydroxyl Acrylic Resin SE6783
SE6783 is a two-component hydroxyl acrylic resin, it has high solid
content, low viscosity, 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 SE6783 is an environmentally
friendly solvent based hydroxyl acrylic resin.
Recommended applications: automobile refinishing paint, motorcycle
finishing varnish , topcoats for steel and plastics, solid color paints.
