Descripción
1K elastic PU foam, which expands and hardens with the humidity of the air and the support. It is characterized by having a high degree of elasticity greater than 35% and a low post-expansion index, which greatly reduces the pressure exerted on the supports. It is a professional quality expanding foam, suitable for all construction supports: concrete, masonry, stone, plaster, wood, cement and mineral fibers, polystyrene, polyester, rigid PVC.
USE
- FM330 is especially indicated for joints that may have expansion, particularly in the construction of wooden structures. It is used for all sealing and insulation applications of frames, doors and windows, roller shutter boxes, partitions, insulating panels, corrugated sheets, attics, pipes, ducts.
- FM330 is a one-component, fast-curing, wet-curing, spray-applied, expandable polyurethane foam with excellent elasticity, airtightness and acoustic properties. Excellent adhesion to bricks, blocks, stone, plaster and cementitious materials, as well as wood, metal and a wide variety of plastics. Low back expansion facilitates greater control during application.
BENEFITS
- The spray has a "2 in 1" application system: it can be applied using a gun or manually using a conical nozzle
- It can be applied in 360º using the conical cannula
- Low post-expansion index: it does not create pressure, thus avoiding deformation of the supports
- Up to 50% elasticity, guaranteeing sealing even in case of movements
- Can be applied at low temperatures (down to -3°C)
- Easy to cut after polymerization
- can be painted
- Up to 63 dB of sound insulation
