Loctite 237129 Two-part Epoxy 200 Ml Cartridge E-120HP

Product Description

The LOCTITE 237129 is a two-part epoxy adhesive supplied in a 200 mL cartridge, designed for high-strength structural bonding in demanding trade and industrial applications. Formulated under the E-120HP series, it delivers a working time of 120 minutes, allowing adequate open time for complex assemblies and large bonding surfaces. The 2:1 mixing ratio is dispensed directly from the cartridge, and the amber-colored mix confirms proper blending. Full cure is reached in 24 hours. Licensed technicians, fabricators, and maintenance professionals working with ceramics, metals, and plastics rely on this adhesive where mechanical fasteners are impractical or insufficient.

The LOCTITE 237129 is suited for repair, assembly, and maintenance work across HVAC, plumbing, electrical, and general mechanical trade applications. The 120-minute working time makes it appropriate for large surface areas or multi-component assemblies where fast-setting epoxies would be impractical. It bonds to ceramic, metal, and plastic substrates, covering the range of materials commonly encountered in equipment repair and component fabrication. The cartridge format is compatible with standard dual-cartridge dispensing guns, reducing waste and ensuring consistent mix ratios on the job.

Key Features

• 120-minute working time supports large-area or complex bonding work
• 4,800 psi shear strength for high-load structural bonds
• Bonds to ceramic, metal, and plastic substrates
• 2:1 mix ratio dispensed from a 200 mL dual cartridge
• Amber color confirms proper mixing at dispense
• 24-hour full cure time under standard conditions

Compatibility

Designed for bonding ceramic, metal, and plastic substrates in structural and maintenance applications where a long working time and high shear strength are required.

Installation Notes

Application is performed using a standard dual-cartridge dispensing gun with an appropriate static mixing nozzle — do not mix manually, as improper ratios will reduce final strength. Clean and degrease bonding surfaces before application to achieve rated shear strength. Avoid disturbing the bond during the working time window and allow a full 24-hour cure before loading the joint. Consult the product safety data sheet for ventilation requirements and skin-contact precautions.
