Junbond weatherproof silicone sealant is a one-part, neutral and moisture cure, medium modulus silicone sealant that provides durable, pliable, watertight joints and offers outstanding adhesion without priming to most non-porous substrates.

With its unique weather-resistant formula, it possesses a balanced adhesive strength and very high recovery, making it ideal to withstand adverse weather conditions in common installations including moisture, movement, sheer, and de-flection, heat and cold resistant, aging resistant, UV resistant .

It is easily gunnable in all weather conditions from -20 to 120 degrees F. Because our weatherproofing silicone caulking requires no mixing and a smaller joint ratio, it is an economical, high-performance alternative to other comparable sealants with a ±40 percent movement capability.
