Coating system for rehabilitation of cracks having chemically aggressive liquids dynamically and mechanically acted upon on substrates

摘要

Coating system for rehabilitation of cracks with chemically aggressive liquids having dynamically and mechanically acted upon by the surfaces, for example, cement-bound floors, concrete surfaces of collecting troughs, collecting and installations for storing, decanting and handling of these liquids or the like, with a primer coating applied on the ground from epichlorohydrin resin and an epichlorohydrin resin - cover layer, wherein the primer and the cover layer in each case are formulated in different ways and is made of a solvent-free mixture on bisphenol a - and / or bisphenol f - base, glycidyl ethers, which is connected as a reaction of a thin, a curing agent on the basis of an amine adduct of a polyamine and / or from the basis of amines with primary, secondary and tertiary amino groups and auxiliary substances and the mixing ratio of resin (component a) and curing agent (component b) for the outer layer 1: 1, characterized in that the component a and / or component b, in addition, internally reactive compounds acting on the permanent elasticity between 2 and 20 w -% and a bonding connections between 1 and 10 w -%, wherein the reactive compounds in the finished cover layer between 80 to 200% in the form of crosslinked.
