Low-Expansion Mounting Foam Quantec PMPL-750 750 ml — can for installation and sealing

Quantec PMPL-750 low-expansion mounting foam is supplied in a 750 ml aerosol can for installation, sealing and insulation tasks. Formulated to deliver controlled, low expansion, this foam is intended for precise application around window and door frames, in joints and gaps where limited swelling and accurate dosing are required. It bonds to common building materials and provides thermal and acoustic sealing while reducing the need for mechanical fasteners in many mounting applications.

Advantages

The low-expansion formula reduces pressure on frames and minimizes deformation of adjacent components. The 750 ml can provides sufficient volume for multiple medium-sized installations while maintaining ease of handling. Controlled flow and curing characteristics enable neat application and predictable foam yield, and compatibility with common substrates ensures good adhesion for durable sealing and insulation.

Suitable for

• Installing and sealing window and door frames
• Filling gaps and joints in walls and around penetrations
• Thermal and acoustic insulation of cavities
• Mounting tasks that require minimal expansion to avoid frame distortion

Key specifications

• Volume: 750 ml aerosol can
• Expansion: low-expansion formula for controlled swelling
• Application: handheld spray/applicator for gap filling and mounting
• Curing: foam cures to a stable, closed-cell structure suitable for insulation and sealing
• Adhesion: compatible with common building substrates such as wood, concrete, brick and certain plastics

How to use

Shake the can thoroughly before use and attach the applicator nozzle according to the manufacturer's instructions. Apply the foam from the bottom of the gap upwards, filling no more than approximately 40–60% of the joint volume to allow for expansion. Maintain a consistent, steady pressure on the valve for even flow. After partial curing, excess foam can be trimmed with a knife and finished with sealant or trim as required. Follow safety and ventilation recommendations during application and curing.

Usage recommendations

Use on clean, dust-free and slightly damp substrates for optimal adhesion. Protect adjacent surfaces from overspray and allow full cure before subjecting the sealed area to load or finishing. Store the can upright in a cool, dry place and avoid exposure to temperatures outside the labeled storage range.
