Stepan® STEPANPOL Polyester Polyols Improve Adhesion between Concrete and Final Coating for More Durable Finishes

Concrete primers create moisture barriers which prevents blistering. Primers work by forming covalent bonds with coating materials, allowing the porous concrete surface to be penetrated and creating a strong mechanical lock. Used to 2K systems, Stepan® STEPANPOL® PC 160-01 has excellent bonding strength to concrete on both wet and dry surfaces. Stepan® STEPANPOL® polyols have very good hydrolysis resistance and weatherability to ensure longevity.

Stepan® STEPANPOL® PC 130-01 is a polyester polyol with great working time when compared to other competitive grades, this increased working time can enable the final topcoat to applied to primers whilst still wet – creating an even stronger mechanical bond. Both STEPANPOL® PC 160-01 and STEPANPOL® PC 130-01 have very low water vapour transmission rates (WVTR), allowing technicians’ great moisture control during applications.
