3M™ Fastener Adhesives 2353 (blue) and 2353Y (yellow) are microencapsulated, room-temperature curing adhesives that enhance the anchorage of threaded fasteners. The adhesives are designed to be coated on the fasteners and dried; 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 are fasteners for the engine compartment or safety-related parts.
This is a normal temp formula that is designed for applications where the service temperature will not exceed 116°C (240°F).
Fasteners with these products can be reused a few times, provided the fasteners are not wire brushed or cleaned with toluene or a similar solvent.
