FS125 is a one-part, neutral curing, low modulus, low odour silicone sealant suitable for perimeter joint sealing applications with high movement capability. It has excellent primerless adhesion to multiple surfaces including masonry, brick, aluminium, PVC-U, polycarbonate, polyacrylate, wood, painted wood, glass and glazed surfaces.
Usage/purpose
FS125 is ideal for use in expansion & curtain wall joints, perimeter joints around windows or doors, panel joints between most common substrates, heel and toe beads, polycarbonate glazing and other general joint sealing applications.
Not suitable for some substrates such as neoprene, butyl
rubber, EPDM, bituminous or tar-containing surfaces.
Contact with bituminous or tar-containing surfaces can
lead to discolouration and failing adhesion. Not suitable for
trafficable joints or areas subject to abrasion. Not suitable for
over-painting. For safe sealing on natural stone use FA870/
FA880. On other sensitive substrates test first.
Safety data sheet must be read and understood before use.
