Abstract

PURPOSE: To prepare the titled resin composition useful as a raw material resin for concrete placing forms capable of giving even a complicate concrete form in high accuracy, and having excellent releasability, heat resistance and alkali resistance, by compounding a polyisocyanate compound and an active hydrogen-containing compound at a specific ratio.
CONSTITUTION: The objective composition is prepared by mixing (A) a polyiso- cyanate compound having an average molecular weight of ≤20,000, pref. 10,000W 174, and an NCO equivalent of ≤10,000 pref. 5,000W87 (e.g. tolylene diisocyanate), and (B) a compound having active hydrogen and having an average molecular weight of ≤10,000, pref. 7,000Wseveral tens, and OH equivalent of ≤5,000, pref. 350Wsereal tens, wherein the amounts of both components are selected so as to give the average functional groups of both components of 2W4, pref. 2W3, the NCO/OH equivalent ratio of 0.5W2.0, pref. 1.0W1.7, and the average functional group equivalent of both components of 200W10,000, pref. 300W 6,000.
