BOND IT AIRTIGHT SEAL THERMAL & ACOUSTIC EXPANDING FOAM

Bond it Airtight Seal Expanding foam is a PU-based flexible expanding foam that has been specially designed to form an airtight seal around windows, door frames etc. It has excellent adhesion to brick, block, stone, plaster, and cementitious materials as well as wood, metal, and a variety of plastics. The low post-expansion facilitates greater control during application. Also benefiting from improved thermal and acoustic insulation. Airtight sealing (independently tested by Rossenheim Labs) <0.1m3 / [h.m(daPa)2/3] according to EN 12114:2000. All-season use: application temp -5oC to +30oC. Zero curing pressure <0.7 Kpa & low post expansion. Avoids deformation of building elements. Permanently elastic foam: ideal for sealing joints subject to movement or pressure sensitive applications. High thermal and sound properties. Tensile Strength > 55 Kpa. Elongation 20% Fast setting. Yield per 750ml = 45 Litres. B2 Rating according to DIN 4102-1. Accoustic dampening - up to 63dB. 750ml can size.
