3M Scotch-Weld Acrylic Scotch Weld, 490 ml

This scotch weld is an acrylic adhesive formulated for joining metal and plastic components in industrial contexts. It is supplied in a bulk 490 ml package and is intended for applications where a robust, long-term bond is required across steel and stainless-steel substrates. The product operates effectively in low-temperature environments down to -40°C and is suitable for use in sectors such as automation, electronics, electrical and mechanical engineering.

• Acrylic chemistry provides structural bonding for mixed substrates
• 8 min setting time reduces fixture duration on assembly lines
• Viscosity 15,000–80,000 cP supports controlled gap filling
• Strong holding characteristic improves long-term joint integrity
• Specific gravity 1 enables predictable dosing and formulation consistency
• RoHS-exempt status clarifies regulatory classification for certain installations

• Suitable for bonding steel panels in automated assembly lines
• Ideal for joining stainless-steel parts in electrical enclosures
• Used for adhering plastic-to-metal assemblies in mechanical fixtures
• Can be used for structural repairs on metal frames in production equipment

Initial handling strength is achieved after the 8 min set period, with full cure reached at 24 h under typical conditions.

The 15,000–80,000 cP range provides thixotropic behaviour that resists sagging while allowing extrusion through dispensing systems.

The adhesive remains functional at service temperatures down to -40°C

Metallic substrates such as steel and stainless steel are specifically compatible and deliver optimum adhesion when surfaces are prepared correctly.
