BCF 750 B3 is a mono-component hardening foam that reacts to humidity. BCF B3 foam can be used for gluing and insulation jobs; for example: assembling door coatings, insulating and sealing window gaps, and in the controlled, workman like ﬁlling needed to build windows and blinds. And to ﬁll in joints in outer door coatings and to ﬁll small wall breakages or other cavities with foamed material. BCF B2 is aself-expanding, self-extinguishing, mono-component, ready-to-use foam based on polyurethane. The foam has an excellent hole and depression ﬁlling capacity and can be used for sound-prooﬁng and lagging. BCF 750 REI is a mono-component, polyurethane, self-expanding, ready-to-use foam. This foam contains harmless propellants for the ozone layer. The product guarantees effective insulation from smoke and gas,high lagging and sound-prooﬁng, adhesion to most sub-layers. BCF 750 TC aut is a single–component polyurethane assembly foam; this foam is better used to seal and isolate rooﬁng tile; it also adheres to all common building materials such as concrete, brickwork, wood, metals, aluminium and glass. This foam is suitable to ﬁllbreakthroughs in walls and other cavities and has a good sound and thermal insulating capability.
