Emulsifier system for water-dilutable epoxy resin systems with pot life indication |
摘要 |
The use of special condensation prods. (I) as emulsifiers for the prodn. of aq. epoxy resin systems is claimed. These emulsifiers indicate the end of the working time by a sharp increase in viscosity. (I) are condensation prods. of (A) an aliphatic polyol component with a wt.-average mol. wt. (Mw) of 200-20,000, at least 5 wt% of which has a Mw of at least 4000 and (B) an epoxide component contg. at least one epoxide cpd. with at least 2 epoxide gps. and an epoxide gp. content of 500-10,000 mmoles/kg. Also claimed are epoxy resin dispersions contg. (I) and amine hardeners (II) in amts. such that the no. of epoxide gps. z(EP) and the no. of amine H atoms z(H) are in a ratio of (1:0.75)-(1:2.0). |
