Polywater RTV Silicone seals voids and seams on outside electrical apparatus such as meters, boxes, light fixtures, and conduit penetrations to keep them weatherproof.
The RTV Silicone is said to be well suited for numerous external sealing needs. The material is packaged in a 10.3 ounce (305 ml) caulking tube for easy dispersal, and has a re-sealable cap to minimize waste.
Polywater Clear RTV is UV stable, VOC compliant, non-flammable, non-yellowing, non-shrinking, and offers a maximum temperature usage of 400º F. Its waterproof formula allows for 25% movement, contains 100% silicone, and is great for electrical apparatus and solar applications. The material meets industry specifications including FDA CFR 177.2600, USDA Rating P-1; MIL-A-46106, ASTM C920-Type S, NS, Class 25, TT-S-001543A, and TT-S-00230C.
