PURPOSE:To provide the titled composition composed of specific components such as liquid diene polymer containing active hydrogen, aluminum hydroxide, etc., having low viscosity, good workability, and excellent weather resistance, mechanical characteristics and colorability, and useful as a water-proofing material, coating material, etc. CONSTITUTION:The objective composition is prepared by compounding (A) a liquid diene polymer containing active hydrogen (e.g. butadiene homopolymer) with (B) aluminum hydroxide and/or calcium bicarbonate, (C) titanium oxide (e.g. titanium dioxide) and (D) an organic polyisocyanate compound (e.g. tolylene diisocyanate). Preferably, the sum of the components B+C is 10-200pts.wt. per 100pts.wt. of the component A, and the weight ratio of B:C is 93:7-40:60. |
