CARBOXYL GROUP-CONTAINING POLYURETHANE AND HEAT-CURABLE POLYURETHANE RESIN COMPOSITION PREPARED THEREFROM |
摘要 |
<p>A carboxyl group-containing polyurethane is capable of giving cured products excellent in adhesion with substrates, low warpage, flexibility, plating resistance, soldering heat resistance and long-term reliability. The carboxyl group-containing polyurethane includes a structure derived from a polyol compound having 1 to 10 hydroxyl groups and 18 to 72 carbon atoms per molecule. The carboxyl group-containing polyurethane is produced by reacting: (A) a polyisocyanate compound; (B) a polyol compound having 1 to 10 hydroxyl groups and 18 to 72 carbon atoms per molecule; and (C) a carboxyl group-containing dihydroxy compound (other than the compound (B)).</p> |
