3M™ Fastener Adhesives 2353/2353Y

Epoxy adhesives best suited for normal and high-temperature environments with high-torque installations

3M™ Fastener Adhesives 2353 (blue) and 2353Y (yellow) are micro-encapsulated, room-temperature curing adhesives that enhance the anchorage of threaded fasteners. They remain dormant until the shearing action of engaging the fastener into a nut or threaded cavity breaks the capsules and allows the adhesive to cure. Typical applications include fasteners for the engine compartment or safety-related parts.

Plastics prone to stress-cracking should not be used in proximity to 3M Fastener Adhesives.

This is a normal temp formula that is designed for applications where the service temperature will not exceed 116°C (240°F). 3M 2353 Product Sheet

 

Advantages
  • High torque values on coated fasteners
  • Environmental resistance to heat, automotive fluids, vibration, thermal and mechanical shock
  • Extended shelf life (bulk adhesive and coated fasteners)
  • Controlled re-activity (adhesive activates and cures upon insertion)
  • Re-usability (additional capsules break with each re-insertion)
  • Allows controlled application to fasteners (viscosity can be adjusted to achieve target coating weights)
  • Penetrates oil coatings
  • Fast drying
  • Bonds to a broad range of fastener finishes
