3M Polyurethane Construction Sealant 525 is a single-component, moisture-curing, gap-filling elastomeric sealant that creates permanently elastic seals and bonds well to concrete. Skin time in 90-150 minutes.
Creates Flexible Seals on Expansion Joints3M Polyurethane Construction Sealant 525 is a single-component, moisture-curing polyurethane sealant used to seal construction expansion joints. It can seal a wide variety of materials, including plastics, fiberglass reinforced plastic (FRP), sheet molding compound (SMC), aluminum, steel, coated metal and wood. It creates a strong, permanent elastic bond with elongation of over 800%. It will seal a wide selection of materials, including concrete, wood, PVC and metal. This adhesive will perform in temperatures ranging from -22°F/-40°C to 176°F/80°C. Once skin has formed, this sealant can be painted to improve the final finish. Available in cartridges, sausage packs and bulk format to meet your application needs.
Recommended Applications- Sealing expansion joints
