New Universal Structural Bonders for dissimilar substratesHenkel is launching a range of Loctite Universal Structural Bonders whose many attributes have been achieved through new, patented hybrid technology. Henkel describes this launch as another milestone for its Loctite brand. The innovative technology substantially extends the application scope of these adhesives, which also afford improved health and safety benefits.

Loctite Universal Structural Bonders combine the qualities of different adhesives to achieve bond strength, cure speed and durability, providing improved performance on a variety of substrates and the versatility to solve many more design and assembly challenges. New additions will soon be launched for carrying out repairs.

Structural bonding has transformed the way products are designed and manufactured. It enables materials to be selected for their respective performance qualities rather than their compatibility with the joining method; plastics, metals and composites can be freely combined.

The adhesive also creates uniform distribution of loads over the entire bond face, resulting in a very positive effect on static and dynamic stress, and contributing to the durability and reliability of the end-product. Moreover, as the join is relatively invisible, the aesthetics of the product are considerably enhanced.

Fast fixturing

Henkel's hybrid technology combines these attributes with the fixturing and cure speed of an instant adhesive. The new Loctite HY 4090 is a good example of what these qualities mean to design engineers and the potential of the range to improve assembly applications, streamline process steps and bond materials in applications with difficult requirements.

Loctite HY 4090 provides exceptional adhesion and strength on plastic/metal combinations and on rubber materials. Fast fixturing reduces assembly time and a robust cure is quickly achieved, even at low temperature and when there is relatively large gaps between substrates.

This Universal Structural Bonder offers good impact, vibration, moisture and temperature resistance and, as it able to withstand chemical attack, it is suitable for production lines that include a chemical process. The enhanced safety credentials of this adhesive - and the others in this range - also contribute to its wider scope of application.

The well-balanced properties of Loctite HY 4090 make it suitable for general assembly applications involving mixed substrates – especially moulded plastic/rubber or poorly fitting parts – in a high-volume, semi-automated or manual assembly line. Typical applications would be wire harness and gasket bonding, sealing and bonding LED lighting fixtures, motors and loudspeakers. The product is available in easy-to-use 50ml syringes and 400ml cartridges.
