Elastic Gunfoam B2

Zettex Elastic Foam B2 is a permanently elastic foam that has been specially developed to absorb movements of surfaces and joints. As a result, the excellent sound and heat-insulating properties between components, such as the joints of window frames, are retained for a long time. Thanks to the unique formulation, the product can be used at temperatures down to -10 ° C. The development and production of this product meet the strict requirements of the ISO 9001 / EN 29001 quality standards.

Single-component elastic polyurethane foam. CFC-, HCFC- and HFC-free (ozone-friendly and does not contribute to the greenhouse effect).

Available form
Spray can 750 ml

Areas of application:
• Installation of window frames (clean, checked behind filling, with the joints of window frames and external roller-shutters insulated and sealed.)
• Filling joints in outside door frames, but not for the primary installation without other mechanical fastenings.
• The filling of cavity walls, passages for electricity, gas and water supply lines and other openings.

Application instructions

Elastic Foam B2 can be fixed on the Zettex Foamgun. This enables optimal Elastic Foam B2 spraying. Shake the can thoroughly 20 times before use. This ensures optimal adhesion of the Elastic Foam B2. After spraying the Zettex Foamgun can be cleaned with Zettex Foamcleaner and hands can be cleaned with Zettex Cleaning Wipes.
