PolyChim-2004 polyester

 

   PolyChim-2004 is a terephthalic-base saturated polyester which contains catalysts, foam regulators, and other modifying additives. This product is designed for reinforcement of mine workings characterized by higher humidity; waterproofing rock-fill hydraulic structures (dams, dikes, and canal banks); reinforcing and waterproofing systems of structures and their surrounding masses during underground space development in large cities.

PolyChim-2004 is characterized by high penetration capability due to low viscosity; it can polymerize under any conditions of humidity over wide temperature range and has good adhesive properties and mechanical strength.
