3M™ Scotch-Weld™ Polyurethane Reactive (PUR) Adhesives are one-component, moisture-curing urethane adhesives. They are applied warm and quickly form strong, durable bonds on a wide variety of substrates.
Key Features:
100% solids, one-component system
Rapid strength build-up with variable set times
High strength and highly plasticizer-resistant
Broad substrate adhesion (wood, plastics, FRP, metal, glass)
Suitable for bonding heat-sensitive materials
Variants:
TE031 – Extrudable grade, fast set, ideal for plastics (e.g., polystyrene, polyacrylic)
TE040 – Low viscosity, fast set, for wood, plastics, metals, and glass
TS115 HGS – Standard grade, bonds wood, FRP, plastics, metals, glass
TS230 – Sprayable/extrudable, long set time, ideal for large-area plastics, aluminum, glass
Bonding wood, FRP, and engineering plastics (polystyrene, polyacrylic, ABS, PVC, polycarbonate)
Joining plastics to metal and glass (not recommended for metal-to-metal or glass-to-glass)
Assembly in furniture, automotive, construction, and composites industries
Large surface bonding where controlled set time (fast or extended) is required
