Abstract
Clearcoat compositions and methods for forming a clearcoat compositions are provided. In one example, a clearcoat composition includes a binder portion A that includes a polyaspartic ester resin. An activator portion B includes a polyol-modified isocyanate that is a reaction product of a polyisocyanate component and a polyol component. The polyol component includes polycaprolactone polyol.
Claims20
A clearcoat composition comprising:
- a binder portion A comprising a polyaspartic ester resin;
- and
- an activator portion B comprising a polyol-modified isocyanate that is a reaction product of a polyisocyanate component and a polyol component that comprises polycaprolactone polyol.
A clearcoat composition comprising:
- a binder portion A comprising a polyaspartic ester resin;
- and
- an activator portion B comprising a polyol-modified isocyanate that is a reaction product of a polyisocyanate component and a polyol component, wherein the polyisocyanate component has —NCO reactive groups, the polyol component has —OH reactive groups, and the polyaspartic ester resin has >NH reactive groups, and wherein the clearcoat composition has an isocyanate index defined by moles of —NCO reactive groups/(moles of —OH reactive groups+moles of >NH reactive groups) of from about 0.8 to about 1.45.
A method of forming a clearcoat composition, the method comprising the steps of:
- forming a binder portion A that comprises a polyaspartic ester resin;
- and
- forming an activator portion B comprising:
- providing a polyisocyanate component and a polyol component for reacting with the polyisocyanate component to form a polyol-modified isocyanate;
- and/or
- forming the polyol-modified isocyanate, wherein the polyisocyanate component has —NCO reactive groups, the polyol component has —OH reactive groups, and the polyaspartic ester resin has >NH reactive groups, and wherein the polyol component comprises polycaprolactone polyol and/or the clearcoat composition has an isocyanate index defined by (moles of —NCO reactive groups)/(moles of —OH reactive groups+moles of >NH reactive groups) of from about 0.8 to about 1.45.
