818 Winter Pistolen Schaum

Gun-applied polyurethane foam

Product information and downloads

Ideal for use at sub-zero temperatures

When it turns bitterly cold on building sites in winter, our 818 Winter Schaum really comes into its own. Unlike other polyurethane foams, it can be applied at sub-zero temperatures down to -20°C without any difficulty. The reduced amount of moisture required by this product allows it to dry through uniformly – even on cold substrates and at low temperatures. 818 Winter Pistolen Schaum adheres to all common building materials. And it is not only suitable for sealing perimeter joints on windows – it is also ideal for foaming in small gaps in walls, openings for all manner of conduits, and other cavities. The cured foam is semi-hard, predominantly closed-cell, and resistant to ageing and rot.

Applications

Main applications

Illustration Treppen-Fugen
Assembling concrete parts
An extra-powerful professional-grade material can be used to assemble parts under difficult conditions.
Sealing windows and doors on the outside
Long-lasting perimeter joints in outdoor areas require resilient and elastic sealants.

Sealing windows and doors from the inside
Low emitting and elastic sealants allow for air-tight joints, preventing draughts and mould.
Filling wall openings
A safety valve makes it easier to carry out the foaming process in cavities using polyurethane foams.
