Silicone sealing cement, suitable for flexible joints in sanitary and wet areas of bathrooms, kitchens, etc. It is resistant against fungi and cleaning agents. It has ideal adhesion to ceramics, glass, anodized aluminium, and similar materials. As a consequence of the acid hardening, this product is not suitable for metallic (zinc, steel, and others) and mineral (concrete plaster, marble, and others) bases. Using the PRIMER NP, adhesion to absorbent/non-absorbent bases will be significantly increased.
