POLYMER COMPOSITION FOR COATING METALLIC AND CONCRETE SURFACES AND METHOD OF MAKING COATING Russian patent published in 2008 - IPC C09D181/04 C09K3/10 E01D19/08 

FIELD: construction; chemistry.

SUBSTANCE: invention can be used when making single-layer polymer coating driveways of bridge floors of metallic and concrete bridges, and more specifically to polymer compositions of obtaining and using the coating. The composition contains liquid thiocol (polysulfide oligomer), manganese dioxide, dibytyl phthalate, diphenylguanidine, indene-cumaron resin, polymeric petroleum resin, sodium bichromate, oligoester acrylate, oleic acid, cement, textile cord, carbon black, granite and rubber crumps, acetone and toluene. The composition is packed in two-components, and before depositing the two parts (component A and component B) it is mixed, formed and used. The prepared surface is initially coated with an adhesive layer of mastic based on polychloroprene caoutchouc or sealing composition based on thiocol-polysulfide oligomer, and then the polymer composition described here above and the coating are solidified at positive ambient air temperature.

EFFECT: obtained coating has high water-proof properties, abrasion resistance and longevity.
