Tec7 FoamTack 750 ml – Low-Expansion PU Adhesive Foam

Tec7 FoamTack 750 ml is a powerful polyurethane adhesive foam designed for fast, precise and insulating bonding of construction materials. Its very low post-expansion makes this PU bonding foam suitable for indoor and outdoor applications. Ideal for insulation boards, aerated concrete, plasterboard and various installation projects.

Reliable Bonding and Excellent Insulation

Tec7 FoamTack provides a professional bonding solution where strong adhesion, fast application and thermal insulation are important. The adhesive foam bonds well to a wide range of building materials and helps reduce thermal bridges at joints.

Its very low post-expansion of less than 1% helps keep bonded panels and construction elements accurately positioned. This reduces deformation and prevents boards or interior fittings from being pushed out of place during curing.

Key Features / Benefits

• Powerful PU adhesive foam for fast and reliable bonding.

• Very low post-expansion: less than 1% deformation.

• Suitable for indoor and outdoor applications.

• Applicable at ambient temperatures from -5°C to +30°C.

• Good adhesion to various construction materials.

• Thermal insulation with a conductivity coefficient of 0.034 W/mK.

• Acoustic insulation up to 60 dB according to the stated technical specifications.

• Bond can be load-bearing after approximately 60 minutes under standard test conditions.

• Pink polyurethane foam supplied in a convenient 750 ml aerosol.

Applications / Uses

• Bonding rigid insulation boards to help prevent thermal bridges.

• Installing aerated concrete blocks and other non-load-bearing construction elements.

• Fixing plasterboard panels to walls and frameworks.

• Installing furniture panels and interior fittings.

• Installing window sills.

• Securing electrical installation boxes.

Application Instructions

Shake the can vigorously for at least 30 seconds. Apply adhesive beads to a clean, stable surface. Join the components after approximately two minutes, before skin formation. Support vertical bonding for around ten minutes if necessary.

The ambient temperature should be between -5°C and +30°C. The product temperature should be between +5°C and +25°C, ideally around +20°C. Lightly misting the surface can help promote curing.
