WURTH B3 Gun Grade Expanding Foam 750ml PU Insulation Filler Window Door Mountin

Würth PURLOGIC® TOP PU Gun Foam

DESCRIPTION

Würth PURLOGIC® TOP is a high-quality polyurethane gun foam developed for filling, sealing, insulating and mounting applications in construction and installation work.

It provides excellent adhesion to virtually all common construction substrates, except polyethylene (PE), polypropylene (PP), PTFE and silicone. Once fully cured, the foam forms a fine-celled, uniform and dimensionally stable structure with no volume shrinkage and only minimal post-expansion.

Its effective sound and thermal insulation properties make it a practical alternative to traditional insulating materials such as mineral wool, cork and fibreglass.
