DRI-LOC®

Dri-Loc® Pre-Applied Adhesive Chemical Additive Type

-65°F to +400°F

Reusability per IFI 125 and IFI 525 (Single Use Only)

Long-Lok is proud to offer Dri-Loc® adhesive coatings for standard fasteners and other threaded components. Dri-Loc adhesives (from Loctite Corporation), applied to threaded parts, form a unique coating that converts ordinary fasteners into self-locking fasteners. Dry to the touch, Dri-Loc adhesives become an integral part of the fastener and stay inert until parts are used. During the assembly process, Dri-Loc adhesive is activated by assembly forces, releasing anaerobic adhesive which locks parts securely.

SPECIFICATIONS

Dri-Loc adhesives are applied to the full circumference of the fastener. Resin fills all voids in the threads when installed, and cures to form an excellent seal to both liquids and gases. (For pre-applied non-locking thread sealant, see Vibra-Seal® information beginning on Page 42.)

Dri-Loc adhesives are designed for applications where specific shear strengths, temperature range and substrate types are necessary. All Dri-Loc adhesives harden in the absence of air on ferrous and nonferrous metals without primer, activators or heat.
They exhibit controlled lubricity, low on torque and are dry to touch for ease of assembly with automatic or hand tools.

For convenience, coatings are color coded to indicate strength range and for easy inspection. Bolts with diameters of 1/16” through 3/4” and with shank lengths of 3/8” to 6” can be coated with our specially developed equipment.
