Performance
This product was used in a number of fire resistance tests employing the general procedures and criteria or BS476: Part 22: 1987. It was used for sealing around a number of penetrations and expansion joints. Integrity ratings of up to 240 minutes were achieved.

This silicone sealant product can be used on heating stoves but it MUST NOT BE USED NEAR NAKED FLAMES OR HOT GASES as this can cause the silicone to have a VERY SMALL BLUE FLAME & the silicone can turn to a powder.

IMPORTANT INFORMATION FOR LOG & COAL FIRE BURNERS
Envirograf® Silicone Sealant has been tested in fire furnaces for up to 4 hours and 1200°C, where joints in walls are sealed and any vapours burn off in the furnace to leave the fireproof seal. When sealing in situations, which normally have adjacent flames, it is absolutely essential that you allow 3 days WITHOUT FLAMES, for every 1-2 mm of Silicone Sealant installed, in order to set the silicone into its fireproof state. For example, 5-6 mm of Silicone Sealant installed would require 4-5 days for the silicone to set. DO NOT allow flames in the vicinity of setting silicone.
