Silicone and Silicone Hybrid Sealants

life seal

The world of RV sealants can be daunting, especially if you are new to the topic. Today, we’ll introduce silicone and silicone hybrid sealants. First off, why choose a silicone-based sealant? Well, silicone sealants join together surfaces by providing a waterproof seal. All conditions weatherproof, silicone provides a tenacity that can withstand nature’s harshest elements. Incredibly strong and durable, silicone and silicone hybrid sealants provide great options for sealing off windows, doors, joints, and other areas exposed to the environment.

Why choose a high-grade sealant?

Probably the greatest selling point of silicone sealants is that they are compatible with plastics, whereas polyurethane and polysulfide sealants are not. Favored in the RV, marine and automobile industries, silicone sealants are great options for any fiberglass RV repair as they are incredibly strong waterproof adhesives. But not all silicone sealants are made the same. There are construction grade silicone sealants, and then there are high-grade silicone sealants. When sealing cracks and gaps, we recommend selecting a high-grade sealant to do the job. Not only are high-grade sealants built to last in all terrain and weather conditions, they are waterproof, prevent mildew, and some have UV resistance. Try RVbyLIFE’s Silicone Rubber Sealant for a 100% high-grade silicone sealant that won’t corrode or yellow over time. A great all-purpose alternative to other RV silicones on the market as the product is waterproof, tack-free in only 30 minutes or less and will fully cure within 24 hours.

RV silicone sealant hybrids

In addition to 100% silicone sealants, silicone sealant hybrids also exist. Silicone sealant hybrids usually contain another polymer that gives the formula its flexibility. Typically fast-curing, tenacious, sandable and paintable, silicone sealant hybrids make good options for adhering multiple surfaces. This is especially true for surfaces that require movement between one another, and those in the presence of water.

For example, RVbyLIFE’s LifeSeal® is a unique formula that combines high-grade silicone and polyurethane for use on fiberglass and any surface that comes in contact with water. Offering a fast-curing, low odor, high adhesion, non-sagging, non-corrosive, and non-yellowing formula, LifeSeal provides a durable permanent watertight seal. What’s more, the produce is completely removable without causing damage to the substrates. Mildew resistant and acid free, LifeSeal is great for sealing windows, doors, joints and other fixtures. Available in five colors from the factory, LifeSeal is also available in custom color matching.
