Loctite 237103 Two-part Epoxy Adhesive 200 Ml Cartridge

Product Description

The LOCTITE 237103 is a two-part epoxy adhesive supplied in a 200 mL dual-cartridge format from the E-40FL series. It delivers a 40-minute working time after mixing, giving installers and technicians adequate open time for precise part alignment before the bond sets. The 1:1 mix ratio simplifies dispensing when used with a standard dual-cartridge gun. Once applied, the adhesive reaches full cure in 4 to 12 hours. The cured bond is gray in color and achieves a shear strength of 3,750 psi. It is used across trade and industrial applications where a structural, high-strength bond is required on a variety of substrate types.

This adhesive is suited for use in mechanical, HVAC, plumbing, electrical, and general industrial maintenance applications. The 40-minute working time makes it practical for larger bonding jobs or multi-step assemblies where fast-cure epoxies would be too restrictive. It bonds to ceramic, glass, masonry, metal, plastic, rubber, and wood, making it a versatile option for mixed-substrate repairs and fabrication tasks encountered in the field or shop. The cartridge format reduces mixing errors compared to manual two-part systems.

Installation Notes

Dispense using a dual-cartridge gun to ensure proper 1:1 ratio delivery. Clean and dry all bonding surfaces before application to achieve rated shear strength. Allow full cure of 4 to 12 hours before applying load to the bonded assembly. Follow applicable safety data sheet guidelines for ventilation and skin contact when handling uncured epoxy components.
