MICRPRIMER PU is a one component, low viscosity, 100% aliphatic polyurethane based primer suitable for all substrates.It is characterised by its very low viscosity, excellent impregnation, non-yellowing (non-staining) properties combined with a relatively fast cure speed and most importantly its excellent adhesion on both non-porous and porous substrates. The cured film displays good mechanical properties: Its elongation is >50%, and its tensile strength surpasses 40 N/mm2.
- Primer for Hyperseal Sealants when a non staining primer is required
- Primer for ceramic tiles
- Primer for non-porous substrates like glass, marble & metals
- Concrete sealer
