TP651 is an impregnated, pre-compressed multi-functional sealing tape. It is comprised of open-cell polyurethane soft foam, impregnated with flame-retardant synthetic resin. The different vapour diffusion properties are achieved through a unique, one-sided patented side impregnation. The impregnation also protects the tape against mould and fungi.TP651 utilises the property of water-vapour permeable sealing, making it less permeable inside than outside (inside tighter than outside principle).
A highly versatile applicator which has been designed specifically for use with SP925 Air Seal.
