Title:
PRODUCTION OF COLD-SETTING COATING-WATERPROOFING MATERIAL
Document Type and Number:
Japanese Patent JP3445364
Kind Code:
B2
Abstract:
PURPOSE: To produce the subject waterproofing material capable of stable cold application over the whole year and formation of an excellently finished cured coating film excellent in heat resistance and useful for a poured flooring material, etc., by using aromatic polyamines composed of a prescribed ratio of diethyltoluenediamine and a specified amine as the curing agent.
CONSTITUTION: This waterproofing material is composed of (A) a main agent composed mainly of a prepolymer synthesized by reacting (i) toluylene diisocyanate with (ii) a polyol and having isocyanate terminals and (B) a curing agent composed mainly of an aromatic polyamine. The waterproofing material is produced by using a mixture of (iii) 30 to 90mol% diethyltoluenediamine and (iv) 10 to 70mol% aromatic secondary amine of the formula [R1 is a 1 to 4C alkyl; (n) is 0 to 2] as the component (B), blending the main agent with the curing agent at a job site so that the equivalent ratio of the isocyanate groups in the main agent to the amino groups in the aromatic polyamine of the curing agent may be 0.8 to 2.0, applying and curing it.
