Product Description
3M Scotch-Weld Urethane Adhesive 604NS is a two-part, non-sag polyurethane adhesive for structural and semi-structural bonding where gap filling and vertical or overhead application are important. In the DP604NS Duo-Pak configuration, the 1:1 components dispense as a bubble-free non-sag paste with a typical 4-minute work life, 20-minute tack-free time, and 6-hour full cure at 25 deg C. The adhesive is used with concrete, ceramic, wood, glass, metals, plastics, and rubber in construction, maintenance, and assembly work. Its rapid setting profile and sag resistance suit bonded joints that must stay in place during cure.
Key features
- Non-sag gap filling: The mixed adhesive stays as a non-sag paste for vertical and overhead bonding while filling joint gaps.
- Rapid working and cure: DP604NS has a typical 4-minute work life, 20-minute tack-free time, and 6-hour full cure at 25 deg C.
- Multi-material structural bonding: The adhesive is used with concrete, ceramic, wood, glass, metals, plastics, and rubber in construction and assembly work.
Applications
Applications include structural and semi-structural bonding of concrete, ceramic, wood, plastics, rubber, metals, glass, and selected construction assemblies.
