Silicone Adhesives & Sealants

Silicone adhesives are valued for their flexibility, temperature resistance, waterproofing properties, electrical insulation, UV resistance, and versatility. They provide durable and reliable bonding solutions in various construction applications.

Silicone adhesives are available in different formulations, such as one-part or two-part systems, and can be applied using methods like squeeze tubes, cartridges, or syringes. Proper surface preparation and curing conditions are essential for achieving optimal bonding performance with silicone adhesives.

How to Choose the Best Silicone Adhesives

There are lots of silicone adhesives on the market, many of which make similar promises in terms of their uses and applications. We stock the trade’s most popular and trusted adhesives, many of which come with certain features which make them more suited to specific tasks:

Flexibility: Silicone adhesives exhibit excellent flexibility, allowing them to withstand movement, vibrations, and thermal expansion and contraction without losing their bonding capabilities.

Temperature Resistance: Many silicone adhesives have a high resistance to extreme temperatures, both high and low. 

Fire Resistance: Some specialist sealants come with ingredients such as graphite, which help improve their fire protection properties.

Waterproofing and Moisture Resistance: Silicone adhesives are inherently water-resistant, although some have even stronger moisture-resistant properties for things like outdoor and bathroom use.

Electrical Insulation: Silicone adhesives possess excellent electrical insulation properties, making them suitable for bonding and sealing electronic components. 

UV Resistance: Some silicone adhesives are formulated to resist degradation from exposure to ultraviolet (UV) light, which is an important factor to consider when using them for outdoor applications.

Versatility: Most silicone adhesives can bond with various materials, although some are designed with unique materials in mind, such as metals, glass, ceramics, plastics, and substrates.
