AQUEOUS POLYURETHANE DISPERSION ADHESIVE COMPOSITIONS WITH IMPROVED HEAT RESISTANCE. |
摘要 |
<p>Aqueous dispersion adhesives of anionic polyurethanes which have high heat resistance and low activation temperature, even when employed without addition of a crosslinker. The polyurethane is the reaction product of an isocyanate terminated polyurethane prepolymer, and a chain extender. The polyurethane prepolymer is the reaction product of a polyol component and a diisocyanate component, the polyol component including: a sulfonated polyester polyol, a hydroxy carboxylic acid of the formula: (HO)xR(COOH)y wherein R represents a straight or branched, hydrocarbon radical containing 1 to 12 carbon atoms, and x and y represent values from 1 to 3, and a low molecular weight aliphatic diol having a molecular weight of from 60 to 400.</p> |
