Rockwool Fire Resistant Silicone Sealant 310Ml 

Fire Rated Silicone Sealant
The excellent Fire Rated Silicone Sealant provides an effective solution to combine joints together with a high movement capability, or where they are formed between dissimilar substrates, such as steel and masonry. As a high specification product, the fire stopping sealant consists of one part alkoxy cure silicone, ensuring excellent un-primed adhesion to the majority of building surfaces. Easy to install, the application of ROCKWOOL Fire Rated Silicone Sealant is simple as the product is extruded from a cartridge loaded into a standard sealant gun. The depth of the joint will depend on the gap to be filled and the fire rating required. Whilst no priming is required for most construction substrates, it is recommended that a small area is tested on substrates to gauge the finish. The sealant should not be applied if the ambient temperature is below 5° C as adhesion will be impaired.
