Abstract

PURPOSE: A composition consisting of a polyol containing ethylene oxide and its ester, water and a foaming agent is made to react with a polyisocyanate to produce title composition of low density, high strength, and adhesion.
CONSTITUTION: (A) The first composition obtained by mixing the major components composed of (a) a polyol, (b) water, (c) a foaming agent, (d) a catalyst and (e) auxiliaries, with (f) a compound having groups with active hydrogens in the molecule, containing more than 50% of ethylene oxide and having 1,000W 61,000 molecular weight and (g) a product obtained by esterification or acid treatment of component f with an acid anhydride such as phthalic anhydride or an acid such as sulfamic acid followed by neutralization of the product with an alkali is blended with (B) the second composition mainly containing polyisocyanate where f/g is 70/30W10/90 and (f+g)/a is 1W30, preferably 5W30/100.
USE: An adhesive for PVC leather, suitably used in interior material for cars.
