Low-Pressure Mounting Foam Bisan 750 ml for Gun — 750ml canister, gun-applied, low-expansion

Low-pressure mounting foam Bisan 750 ml for Gun is a low-expansion polyurethane assembly foam supplied in a 750 ml canister designed for use with a foam gun. It is formulated for controlled, low-pressure application to reduce overspill and ensure even fill in joints and cavities. The product is intended for sealing, filling and providing thermal and acoustic insulation around windows, doors and other building openings where precise dosing and minimal expansion are required.

Advantages

The gun-compatible packaging enables accurate, incremental application and improved control over bead size compared with straw-dispensed foams. Low-expansion properties minimize deformation of frames and fixtures during curing and reduce the need for trimming. The foam provides good adhesion to common building substrates and cures to a stable closed-cell structure that contributes to thermal insulation and sound reduction. Using a gun reduces product waste and makes application in narrow gaps and overhead work easier.

Suitable for

• Sealing perimeter joints around window and door frames
• Filling gaps and cavities in wall and ceiling constructions
• Thermal insulation of cold bridges and small voids
• Acoustic sealing of service penetrations and partition connections
• Installation tasks that require precise dosing and limited expansion

Key specifications

• Volume: 750 ml canister for gun application
• Foam type: low-expansion polyurethane assembly foam
• Application method: foam gun (gun-applied)
• Functional properties: sealing, filling, thermal and acoustic insulation
• Expansion behaviour: low-expansion for minimal stress on frames

How to use

Attach the canister to a compatible foam gun according to the gun manufacturer’s instructions. Shake the canister gently before mounting. Apply foam from the bottom of the joint upward, filling cavities incrementally to allow for controlled expansion and curing. Avoid overfilling — leave space for the foam to expand where specified by installation requirements. After skin formation, excess cured foam can be trimmed and finished with appropriate sealants or coverings. Follow ventilation guidelines and allow the foam to cure fully before exposing it to finishing work.

Usage recommendations

Use personal protective equipment such as gloves and eye protection during application. Store canisters upright in a cool, dry place and keep them away from open flames and temperatures outside the manufacturer’s recommended range. For best results, use a compatible low-pressure foam gun and apply at recommended substrate and ambient temperatures; consult technical data for exact conditions.
