BoscoSeal Zinc Primer

Bostik Boscoseal Zinc Primer is a one component, low viscosity, polyurethane based primer suitable for many different substrates. It is characterized by its very low viscosity and balanced curing speed that result in excellent wetting, impregnation and paint-over time on different substrates, whether of high, low or no porosity (e.g. glass and metals). Additionally, it can be effectively used on both dry and wet concrete, even green concrete, not only as primer but also as a low-cost sealing solution, increasing, thus, the durability of the substrate.

The cured film displays outstanding mechanical properties: Its elongation is >300% and its tensile strength surpasses 30 N/mm2.
Apply with brush or roller. Consumption: 100-300 gr/m2, subject to substrate porosity.
