Loctite 4062 Yellow Quick Set Rubber-Toughened Instant Adhesive – 113g for Impact-Resistant Bonding

Loctite 4062 is a rubber-toughened, yellow-tinted quick-set cyanoacrylate (CA) instant adhesive from Henkel, designed for high-volume production and MRO bonding applications requiring fast cure combined with enhanced impact and peel resistance not available in standard cyanoacrylate formulations. The rubber toughening agents incorporated into the CA formulation significantly improve the fracture toughness of the cured adhesive, making it suitable for dynamically loaded joints that would cause brittle failure in standard CA adhesives.

The 113g bottle provides a large, economical supply of Loctite 4062 for production operations, high-consumption MRO facilities, and bonding applications where frequent reordering of smaller bottles creates supply disruption. The precision dispensing tip provides controlled drop application for consistent adhesive dose on each bonding application.

Like all cyanoacrylate adhesives, Loctite 4062 cures by anionic polymerization initiated by surface moisture and weak base on the substrate. Cure is virtually instantaneous on close-fitting joints, providing immediate handling strength without fixturing. The yellow tint aids visual identification of the product and applied adhesive coverage on bonded surfaces.

Technical Information

Loctite 4062’s rubber toughening is achieved through the incorporation of elastomeric rubber particles distributed throughout the cyanoacrylate matrix. When a crack forms in the cured adhesive under impact or peel loading, the rubber particles bridge the crack faces and absorb energy, preventing rapid brittle crack propagation through the adhesive. This toughening mechanism dramatically increases the energy required to fracture the bond compared to untoughened CA adhesives, providing a significant improvement in impact drop tests and dynamic loading scenarios.

The quick-set characteristic means the adhesive builds handling strength within seconds of joining the adhesive-coated surfaces — faster than standard CA grades due to the optimized photoinitiator and accelerator system. This fast fixture time enables very short cycle times in production bonding operations where many small joints are bonded in sequence.

For maximum bond strength with Loctite 4062, surfaces should be clean and free of oil, grease, and loose contamination. Very smooth, close-fitting surfaces cure fastest and strongest with CA adhesives. Rough or porous surfaces slow cure due to the larger adhesive mass that must be reacted by the limited available surface base and moisture. A CA activator (primer) can be used to accelerate cure on slow-curing substrates.

Frequently Asked Questions

Q: What makes Loctite 4062 different from standard CA adhesives?
A: Loctite 4062 is rubber-toughened, providing significantly higher impact resistance and peel strength than standard cyanoacrylate adhesives while maintaining the fast cure speed CA is known for.

Q: What is the MPN for Loctite 4062 113g bottle?
A: MPN is 234044. Product: Henkel 46548 LOCTITE 4062.

Q: What is the cure time for Loctite 4062?
A: Loctite 4062 is a quick-set instant adhesive providing handling strength in seconds. Full strength develops over several minutes to hours depending on substrate and gap.

Q: What substrates does Loctite 4062 bond?
A: Loctite 4062 bonds metal, plastic, rubber, and ceramic substrates. Clean surfaces for maximum bond strength.

Q: Can an activator be used with Loctite 4062?
A: Yes. A Loctite CA activator/primer can be used on slow-curing substrates to accelerate cure. However, activator use may reduce final bond strength on some substrates — refer to Henkel’s guidance for your specific application.
