Microsealer® PU is a one-component, 100% solids, polyurethane based primer suitable for all substrates. It has very low viscosity and balanced curing speed which result in excellent wetting, impregnation and paint-over time on all substrates of high, low or no porosity (e.g. glass and metals).
The product 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 the durability of the substrate.
The cured film displays outstanding mechanical properties. Its elongation is 400%, i.e. it matches perfectly that of the Hyperdesmo® system, and its tensile strength surpasses 20 N/mm2.
Best applied with brush or roller. Recommended consumption rate of 100-500 gr/m2, subject to substrate porosity.
