1C Gun Foam B2

blaugelb 1C Gun Foam B2 is a one-component PU assembly foam with outstanding dimensional stability and adhesion. The volume shrinkage and subsequent elongation after curing are extremely low. Together with the rapid full cure, this allows efficient work and swift further processing. The blaugelb 1C Gun Foam B2 can be precisely dispensed, has high stability and does not collapse when applied. In this way, even larger cavities can be easily filled with several layers of foam.

The high noise and thermal insulation values of the blaugelb 1C Gun Foam B2 ensure an excellent insulating function. The adhesion is outstanding on all standard construction substrates such as concrete, stone, wood, polyester, rigid PVC, polystyrene like EPS and XPS, rigid PIR/PUR foam, corrosion-protected metal, plaster, masonry.

The foam does not adhere to polyethylene, polypropylene, PTFE and silicone, oils, greases, mould release agents or similar materials. (Carry out suitable pretests). Once cured, the foam is semihard, predominantly closed, rot-proof and non-ageing, though not if exposed to UV radiation.

Applications: Filling – Insulating – Sealing: In window construction for the backfilling, insulation and insulation sealing of connecting joints on windows and door frames. For filling wall recesses, roller shutter cases, cable runs and other cavities with foam. For the damming and insulation of window sills.
