With so many sealants on the market today, choosing the right one for the right job can be difficult. Most sealants are designed for specific uses and have different capabilities, although not all sealants have exclusive attributes, as a lot of sealants have usage and application cross over.

The majority of sealants, or at least what I will be discussing below are classed as RTV (Room Temperature Vulcanised) products. RTV’s cure at normal room temperature when exposed to moisture in the air.

General Purpose / Builders Silicone

One of the most widely used silicones available today due to its huge range of application uses. It adheres well to most building materials, providing good elasticity and durability.

Hygiene & Sanitary Silicone

Sanitary silicone features a powerful antibacterial and mold resistant formula, designed especially for applications in areas of increased humidity such as in kitchens and bathrooms.

Glass & Glazing Silicone

Glazing Silicones usually cure to a very clear finish, offering excellent adhesion to glass and similar substrates. Ideal for bedding glazing panels and sealing the edge of glass in windows and doors.

Neutral Cure Silicone

The majority of silicone sealants expel a characteristic vinegar like smell when curing. Not only is this smell undesirable in some circumstances, it can also have a negative impact on certain materials (polycarbonate materials may suffer slight staining for example). Neutral Cure Silicone is usually a higher quality silicone product, reducing or even eliminating the production of acetic acid while curing.

Aquarium Silicone

This silicone is specifically designed for the joining and sealing of glass in aquarium construction and applications. Do not use General Purpose or Building Silicone as it contains toxic materials.

High Temperature Silicone

This type of silicone is designed to be able to withstand high temperatures once cured (usually 260°C - 300°C rated). Typical applications include, use in electrical and industrial applications and creating seals between high temperature surfaces.
