PÜRKAY 028/07 Polyurethane Elastic Self Leveling
Solvent-free, colored, elastic self levelling coating with same elasticity at every point of the surface, two-component polyurethane sports flooring material
Definition and Feature
PÜRKAY 028/07 is a polyurethane based, solvent free, two component, self leveling sports flooring.
It is a waterproof, chemical resistant, elastic, impact and friction resistant, self-leveling coating that does not prevent the elasticity of the rubber sheet on which it is applied.
