- 7,000 cP Warm-Application Viscosity
Product Description
3M Scotch-Weld PUR Adhesive TE040 is a one-component, 100% solids reactive polyurethane hot-melt adhesive supplied as a black extrudable solid. Typical viscosity is 7,000 cP at 121 deg C by Brookfield Thermosel, and typical open time is two minutes for a 3.2 mm bead on a nonmetallic surface. After bond formation, typical handling time is 40 seconds to support a 5 psi tensile load. Moisture curing subsequently develops the urethane bond, with typical cured Shore D hardness 35. The adhesive bonds wood, fiber-reinforced plastics, other plastics, metal, and glass for furniture, cabinetry, profile wrapping, and panel assembly.
Key features
- 7,000 cP application viscosity: The typical value for the black grade is measured at 121 deg C by Brookfield Thermosel.
- 40-second handling time: This typical minimum interval is the time for the bond to support a 5 psi tensile load, not full moisture cure.
- Reactive one-component PUR: The 100% solids hot melt combines initial handling strength with subsequent moisture-curing urethane bond development.
Applications
Wood or plastic bonding for furniture and cabinetry; profile wrapping for windows and doors; panel assembly.
