## Long description

Soudal PIA 870 SOU is a pistol-applied polyurethane assembly and sealing foam supplied in a cartridge format for use with a foam gun. It is formulated for filling gaps, providing thermal and acoustic insulation, and sealing joints in building works. The product adheres to common construction substrates such as masonry, concrete, wood, metal and many plastics, making it suitable for window and door installation, sealing around pipe penetrations and general insulation tasks in new build and renovation projects.
Advantages
Soudal PIA 870 SOU cures to a resilient cellular structure that provides consistent thermal insulation and sound reduction. The foam offers good adhesion to a wide range of substrates and expands to fill irregular cavities while resisting shrinkage. Easy application with a compatible pistol ensures controlled bead placement and reduced waste. The cured foam can be trimmed, sanded and painted or covered with appropriate finishes to integrate with surrounding materials.
Suitable for
 Sealing and insulating gaps around windows and doors
 Filling cavities and voids in walls and floors
 Sealing pipe and cable penetrations
 Thermal and acoustic insulation in renovation and new construction
Key specifications
 Packaging format: cartridge for pistol/foam gun application
 Foam type: one-component polyurethane
 Application method: pistol/foam gun for controlled dispensing
 Curing: forms a closed-cell to semi-open-cell resilient foam after polymerisation
 Performance: provides thermal insulation and sound dampening properties
 Workability: can be cut, sanded and coated after curing
 Substrate compatibility: adheres to masonry, concrete, wood, metal and many plastics
How to use
Use a compatible foam gun and follow safety instructions on the cartridge. Surfaces should be clean, free of dust, oil and loose particles; lightly pre-wetting porous substrates can improve yield and adhesion. Attach the cartridge to the foam gun, shake if indicated by the manufacturer, and apply with steady pressure to fill gaps incrementally to allow controlled expansion. After polymerisation, excess foam can be trimmed with a knife and the surface finished as required. Observe recommended ambient and substrate temperature ranges for proper curing.
Usage recommendations
For optimal results, use Soudal PIA 870 SOU with a compatible pistol designed for cartridge application, provide adequate ventilation during application, and wear suitable personal protective equipment. Store cartridges upright in a cool, dry place and follow disposal guidelines for empty containers.
