Water dilutable coating materials for mineral and bituminous substrates, and method of making them.

摘要

1. Water dilutable coating medium for mineral and bituminous surfaces, particularly for the preparation of road markings and the coating of exterior walls, consisting of a water-emulsifiable combination of (A) at least 30, preferably 50-75% by weight of a solution in organic solvents of a physically drying non-water dilutable organic polymer of the type of acrylic polymers or copolymers, vinyl polymers or copolymers, chloro- or cyclo rubber, bituminous masses or highly acrylated alkyd resins, (B) 10-50% by weight, preferably 15-25% by weight of an alkyd resin rendered water soluble through salt formation and/or an oilfree polyester and/or acrylic and/or vinylcopolymer and/or epoxy resin amine adduct and optionally (C) 15-35% by weight, preferably 20-30% by weight of a plasticising agent, the ratio between component (A) plus optionally (C) and component (B) being in a range of between 8.5 : 1 and 1.5 : 1, preferably between 6.5 : 1 and 3 : 1 and the normal pigments, extenders and auxiliary agents.
