Abstract:
The present invention provides a system comprising an allophanate composition comprising a neutralized polyol, a polyuretdione resin, a tertiary amine catalyst, an additive package, and a reducer; and a neutralized basecoat comprising an inorganic salt and a pigment. The present invention further provides a method of making an allophanate system comprising combining a neutralized polyol with a polyuretdione resin in the presence of a tertiary amine catalyst, an additive package, and a reducer to produce an allophanate composition, and contacting the allophanate composition with a neutralized basecoat comprising an inorganic salt and a pigment. The system may be used to make coatings, adhesives, castings, composites, and sealants in which clear-coating on neutralized pigmented basecoats is much improved in comparison to coating on non-neutralized basecoats.
