3M™ Scotch-Weld™ Epoxy Adhesive 1838
The 3M™ Scotch-Weld™ Instant Adhesive Accelerator AC452 is a one-part, acetone-based activator designed to rapidly accelerate the curing of cyanoacrylate (instant) adhesives. It is particularly effective in applications involving thick bond lines, porous substrates, or situations where a quick bond is essential
Key Features
- Rapid Cure Acceleration: Significantly speeds up the curing process of cyanoacrylate adhesives, making it ideal for time-sensitive applications.
- Versatile Application: Suitable for use on various substrates, including metals, plastics, and rubbers.
- Acetone-Based Formula: Ensures quick drying and effective performance.
- One-Part System: Simplifies the application process without the need for mixing.
Applications
- Bonding thick or uneven surfaces where standard curing times are insufficient.
- Working with porous materials that may absorb adhesives, hindering proper bonding.
- Situations requiring immediate handling strength to expedite production processes.
