コーティング組成物において有用なブロックポリウレタンプレポリマー
Document Type and Number:
Japanese Patent JP2008502774
Kind Code:
A
Abstract:
Blocked polyurethane prepolymers obtained by reacting at least one polyol, a first polyisocyanate comprising diphenylmethane diisocyanate, a second polyisocyanate having a viscosity at 25° C. of less than about 250 mPa.s, a phenol blocking agent, and an oxime blocking agent, wherein the weight ratio of second polyisocyanate:first polyisocyanate is not more than 0.65:1. The blocked polyurethane prepolymers are especially useful in formulating coating compositions additionally comprising at least one acrylic resin, at least one plasticizer, at least one filler, and optionally other ingredients and additives. A cured coating is obtained by applying a layer of the coating composition to a substrate surface and heating the coating composition layer.
