Henkel’s launches LOCTITE® 402, an instant adhesive for the assembly of small components in high-speed production applications as well as quick, on-the-go repairs. LOCTITE® 402 expands the LOCTITE® Instant Component Bonding range.
LOCTITE® 402 is an instant, high-strength adhesive whose features and benefits are designed to help address industry challenges such as productivity, reliability, and design diversification.
Upgraded Health & Safety Credentials
The LOCTITE® Instant Component Bonding range addresses many of the design and assembly challenges faced by manufacturers in their quest to pioneer new products that are innovative, reliable and profitable.
LOCTITE® 402 builds on this foundation with even faster fixture speed, superior heat performance and a unique, patented formula with upgraded health and safety credentials (formulated without the addition of traditional stabilizers such as HQ and MMBP).
Fast Fixturing & High Strength
LOCTITE® 402 handles strength twice as fast on most substrates by comparison with select other assembly solutions (3 – 10 seconds), it meets the demands of modern manufacturing. This fast fixture speed, achieved at room temperature, helps increase throughput and reduces work-in-progress (WIP) for both manual and automated assembly.
Productivity can be increased further with a comprehensive range of LOCTITE® manual, semi-automated to fully automated dispensing equipment that is easily integrated into most production lines.
LOCTITE® 402 is a single-component instant adhesive that bonds most metals, plastics and elastomers as well as hard-to-bond materials with the use of a primer. It provides a single solution for multiple materials and components which helps reduce assembly costs, process complexity and WIP.
With an ever-growing demand for more feature-rich yet smaller components in end-markets such as urban mobility, home automation and power tools, LOCTITE® 402 helps manufacturers to have more options on aesthetics, performance, and design.
Performs in High-temperature Performance
Even in extreme conditions, LOCTITE® 402 delivers more reliable performance compared to many traditional instant adhesives. It demonstrates strength retention on most metals up to 135°C - both tested at temperature ("hot strength") and room temperature ("heat aging") - a big benefit.
For example, for end-products whose power supply and connectivity generate a lot of heat. Improved impact resistance is another feature of this adhesive compared with traditional instant adhesives.
LOCTITE® 402 also sets an important new health and safety milestone for instant adhesives. Its patented formula contains alternate raw materials that support the enhancement of worker and workplace safety.
Several instant adhesive ingredients have come under greater regulatory scrutiny in select regions of the world. Two of these are hydroquinone (HQ) and 2.2’-methylenebis (4-methyl-6-tert-butylphenol) – also known as MMBP - whose primary role is to ensure the adhesive remains liquid in the bottle for the duration of its shelf life.
In response to regulatory change requirements and industry demand for safer assembly solutions, Henkel has exchanged certain raw materials in selected products in its LOCTITE® range of Instant Adhesives.
No HQ and MMBP
Although these raw materials were present in very small amounts in the original formulations, Henkel developed a novel stabilizer package that has allowed HQ and MMBP to be removed from the formulas for the most widely used Instant Adhesive products.
This health and safety breakthrough, in combination with the other technical advancements, make LOCTITE® 402 a desirable alternative to other fastening methods in an even greater number of manufacturing environments.
LOCTITE® 402 incorporates properties from the industry’s top-performing instant adhesives to give those involved in the design and manufacture of innovative products a significant competitive edge.
