nC Protect

4500 Glass Sealant

nC Protect 4500 Glass Sealant is a transparent liquid based on hydrophobic nano technology. The formulation chemically adheres to and in glass surfaces. After application, an invisible bonded matrix of nano-silica and quartz is formed inside and on the surface.

Glass and glazed ceramics become completely dirt-resistant and easy to clean. The glass surface becomes extremely water, grease and dirt resistant and remains protected for 3 to 5 years. It does not affect adhesives or sealants. For glass applications involving extreme heat, such as ovens and process glass up to 750⁰C, look for nC Protect 4510 Heat Glass Sealant.
