Title:
POLYURETHANE RESIN FORMING COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2011/145446
Kind Code:
A1
Abstract:
Disclosed is a polyurethane resin forming composition comprising a polyol (A), an isocyanate terminated prepolymer (B), a catalyst (C), and a reaction inhibitor (D), wherein: the polyol (A) is obtained by means of the transesterification of a polycarbonate polyol (a1), a polycaprolactone polyol (a2), and an aliphatic glycol (a3); the isocyanate terminated prepolymer (B) is obtained from the reaction between a poly(tetramethylene glycol) (b1) and an aliphatic organic diisocyanate (b2); the catalyst (C) is a dibutyl bis(2,4-pentanedionato) tin; the reaction inhibitor (D) is a 2,4-pentanedione; and the mass ratio of the catalyst in relation to the reaction inhibitor is 50 to 667 ((D)/(C)). The polyurethane resin forming composition has an excellent pot life and curing properties, and exhibits an excellent appearance, long-term stability, yellowing resistance, and wear resistance as a coating film.
