Everbuild Tecnic Silicone 825 is a low modulus, neutral curing silicone sealant based on a filled alkoxy curing system, specially formulated to provide extra tool down time on longer joints. Conforms to ISO11600 class F25LM and G25LM when tested to ISO11600.
The sealant is typically used for expansion joints to stone, brick, concrete and composite panels, perimeter pointing around all types of window and door frames, weatherproofing sealing to most external applications, construction and dilation joints where stress does not occur until fully cured.
