MULTIFUNCTIONAL MASTIC POLYMER COMPOSITION FOR PROTECTIVE COATING Russian patent published in 2012 - IPC C04B26/26 C08L95/00 

FIELD: chemistry.

SUBSTANCE: invention relates to construction and particularly to making waterproofing and anticorrosion coatings using chlorosulphonated polyethylene (CSPE)-based compositions. The multifunctional mastic polymer composition for protective coating contains a polymer composition in form of CSPE-20 or CSPE-20 "I" lacquer or CSPE-L lacquer or a polymer composition which is prepared by dissolving dry CSPE at 60°C in an organic solvent - toluene or petroleum xylene, wherein concentration of CSPE in the polymer composition is equal to 10-20%, a vulcanising component - polyisocyanate or polyethylene polyamine and a bitumen composition - bitumen-rubber mastic BRM-20 or Rebax-M or Autocrin (CBPM), with the following ratio of ingredients in wt %: polymer composition 75.1-77.7, bitumen-rubber-mastic 22.0-24.5, polyisocyanate or polyethylene polyamine solution 0.3-0.5.

EFFECT: high adhesion of the obtained coating with the base, breaking elongation and strength.
