(57) [Summary] [Purpose] A polyurethane elastomer composition with good workability, suitable for waterproofing materials, flooring materials, paving materials, etc. [Constitution] 0.0 based on the urethane elastomer composition A room temperature curable polyurethane elastomer containing at least one selected from 05 to 5% by weight of an aromatic carboxylic acid and an acid anhydride of the aromatic carboxylic acid in a main agent or a curing agent, especially a curing agent. Composition. [Effect] The initial curing property is high, the tack is small, and the viscosity of the curing agent can be greatly reduced, so workability is excellent, and high-strength room temperature curing suitable for waterproofing materials, flooring materials, paving materials, etc. A type polyurethane elastomer is obtained. |
