Fireproof Silicone
Product Description
Fireproof Silicone is an flame-resistant, single-component, neutrally interlocking sealant on a polysiloxane base. It is suitable for internal and external use. The material does not contain any solvent or halogens, which means that no toxic or corrosive gases are formed in case of fire. The silicone is weather-resistant and elastic. It also adheres well to a large range of materials including glass.

Possible Applications
Fireproof Silicone is especially suitable for the following applications:
- Sealing joints between enclosing walls
- Sealing connections between wall and ceiling and/or floor
- Sealing window connection joints
- As a sealant for fire-protection glazing
- Sealing pipe ducts, cable ducts, ventilation channels etc.
Adhesion
- Glass: good adhesion without applying primer to glass, ceramic tiles and enamelled bases
- Porous bases: Kerafix Primer MSP Transparent should be applied to porous bases such as concrete, aerated concrete, plaster, stone and fibrous cement
- Metal: Kerafix Primer M is recommended on uncoated metals, such as anodised aluminium, stainless steel, galvanised steel, copper, lead and zinc
Processing
The bases must be clean, dry and free from dust and grease.
- Smoothing: Due to the formation of skin within 15 minutes, press the sealant against the walls of the joint with a jointer or a spaluta and smooth immediately. A mild soap solution prevents adhesion of the sealant to tools. However, avoid getting soap solution between the sealant and the edge of the joint, as this can result in loss of adhesion.
- Hardening:The material hardens out under the influence of the moisture in the air.
Available sizes
Fireproof Silicone is available in 310 ml canisters in the colours: white – black – grey – brown – transparent.
