What Are Silicone Sealants for?

Silicone has become a common adhesive sealing option in numerous industries because of its effectiveness and versatility. These waterproof sealants have excellent mildew and UV resistance, can handle wide temperature ranges, and maintain their colour over time. They form a tight, durable seal while remaining flexible to absorb shocks and impacts. Silicone sealants can also be formulated to have solvent resistance or be electrically conductive.

Common OEM and MRO uses for silicone sealants include installing glass parts on automobiles, filling gaps around building doors and windows, making custom engine gaskets, and repairing marine equipment. Black is the most common colour, but you can find various hues to blend with various materials or call attention as needed.

Form Lasting Seals

We have been helping organisations find the right silicone sealants for over 40 years. Many types of silicone sealers are available, including RTV sealant (room temperature vulcanizing), weatherproofing sealant, glazing sealant, high-temperature sealant, and general-purpose sealant. Different applicators are also in stock like tubes and cartridges. We are known for offering low-volume business order fulfillment, and larger organisations can stock up with bulk discounts and free shipping on orders over £50.
