Material: Vinyl Resin SMOH（similar to“VROH”)
It has good compatibility with other film-forming
material,such as alkyd resins,polyurethane elastomers, isocyanate resin, melamine
resin, urea formaldehyde, epoxy polymers etc. So it is often used with other film-forming
material in order to improve the coating performance,and enhance paint adhesion,flexibility,
tenacity,hardness and chemical resistance. Because of the hydroxyl functional group,it
can also be used for improving the characteristics including alkyd,two-component
polyurethane,and two-component epoxy coatings.
