Synthetic Rosin-Base Waterproof Coatings

摘要

It was established that coatings on the basis of pure PS rosin and epoxy rosins, along with positive qualities, have much brittleness. With the addition of bitumen there is an improvement in the elasticity of the coatings, but their frost resistance and heat resistance diminish. Compositions which contain bitumen can be used for hydroinsulation of interior installations. It was shown that the optimum properties are possessed by compositions which contain the polymeric PS rosin and epoxy rosin with the addition of plasticizers. Such coatings can be recommended for the protection of enclosing constructions which are operated under especially complicated conditions. (Author)
