BASF Masterflex 250

Masterflex 250 is an acrylic based sealant, formulated primarily to perform as barrier to the incursion of fire through expansion joints. Masterflex 250 sealant is also an effective acoustic sealant.

 

Uses

Sealing exterior and interior construction joints that are subject to movement (up to ±20%) in pre-cast concrete panels, block work and brickwork. Sealing gaps around cables, metal pipes, conduits, busways and ducts that penetrate walls, floors and ceilings. If a joint movement is not required, Masterflex 250 sealant can be used as a putty for filling holes in fire rated substrates. Substrates include metal, concrete, plasterboard and cable coverings.
