DOW 796 PVC-U Silicone Sealant Brown 3308626

This brown silicone sealant is specifically formulated for use with PVC-U frames and trims, making it suitable for sealing windows, doors, and other uPVC features on site. The brown finish helps achieve a neat seal that matches dark or brown-finished surfaces, maintaining a coordinated look around fittings.

Typically used externally, it provides a weather-resistant barrier at joints where PVC-U meets masonry, glass, or other materials. The flexible curing accommodates minor movement in the substrate, making it practical for areas exposed to temperature changes and regular use.
