EPOXY-PERCHLOROVINYL COMPOSITION FOR COVERS Russian patent published in 2004 - IPC

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention recommends epoxy-perchlorovinyl composition for covers as a protecting agent for any surfaces - against atmosphere and chemical corrosion. Composition contains epoxy-diane resin, perchlorovinyl resin, amine hardening agent, pigments, filling agent and organic solvent. The novelty involves the additional addition to the composition a plasticizing agent - dibutyl phthalate, dibutyl sebacate or tricresyl phosphate and a mixture of γ-aminopropyltriethoxysilane containing 2.22% of primary and 2.68% of secondary amino-groups and 1.0% of allyl group (-CH₂=CH-CH₂-) with N,N'-diphenylol-p-phenylenediamine (C₆H₅NH-C₆H₄NHC₆H₅) in their mass ratio = 1:1. The combination of components in composition taken in the definite ratio provides high protective, adhesion and strengthening properties of covers in the process of their exploitation.

EFFECT: valuable properties of composition.
