Abstract RU 2690169 C2

FIELD: chemistry.

SUBSTANCE: present invention relates to a polymer protective composition for protecting articles and structures from different materials, including rubber. Polymer protective composition consists of a two-component polyurea composition consisting of an isocyanate-based prepolymer and a poly-aspartic-type curing agent, in which additionally introduced is a modifying additive, in form of which polydimethylphenylsiloxane (PDMPS) is used in amount of 15–30 wt%.

EFFECT: said composition provides a coating having good adhesion to different materials, including rubber, high elasticity, weather resistance and resistance to action of chemical agents, such as mineral acids, alkalis and hydrocarbon media.
