Features & Benefits
- Coatings made with Primer SN prevent Radon (radioactive natural gas present in the soil) from penetrating inside buildings
- Compliant with DIN ISO/TS 11665-13 standards, verified and certified by the IAF accredited laboratory for radionuclide analysis
- Primer SN may be used as it is or mixed with Quartz 0.5 to improve adhesion of resin coating systems and even out surfaces
- Thanks to its special formulation, Primer SN is characterised by its ability to penetrate into substrates and may even be applied on moderately damp surfaces
Recommendations & Limitations
