Tremco SG557 Non-Staining Silicone Weather Seal
Sealing & Bonding Products

Tremco SG557

SG557 is a single-component, neutral curing silicone sealant with good mechanical resistance and adhesion to most common porous and non-porous building substrates. SG557 is designed for use as a weatherseal silicone in applications where substrates demand a non-staining sealant.

Packaging: 300ml cartridge or 500ml foils
Colour: Black, white, light grey, mid-grey, dark grey, beige, bronze and cream

Joint faces should be clean, dry and free from dust, oil, grease, old sealant and any traces of contaminant which may affect adhesion. Any previously applied sealant must be mechanically removed. Movement joints should be back filled with a foam backer rod such as FGT BR135 in order to control the depth of sealant and prevent three-sided adhesion.

Please see data sheet for more information. Please do not hesitate to contact us for further information, pricing or to discuss your sealing & bonding requirements.
