Corrosion inhibiting hardener-contg. epoxy! resin compsn. - contains long chained alkyl amine or salt, e.g. for injection into building construction

摘要

Hardenable epoxide- and hardener-contg. corrosion-inhibiting epoxy resin compsns. contain 1 long-chained prim., sec. or tert. alkylamine, pref. contg. 18-22C alkyl gp., or a basic alkylamine salt, esp. yielding pH 10 in aq. soln. The compsns. are pref. used for injection into building constructions, esp. by vacuum injection, partic. for filling stress channels is prestressed concrete. Adequate corrosion protection can be achieved in the presence of water.
