Henkel Loctite has announced a major breakthrough in adhesive technology with the launch of two new Light Curing Instant adhesives.

The new range comprises Loctite® 4304 low viscosity, and Loctite® 4305 high viscosity adhesives. These clear, one-part, solvent-free systems offer a rapid cure of the exposed adhesive using UV light, whilst achieving an instant adhesive bond without the use of activator or the need for racks to cure products over a long period.

Supplied as 28g or 454g packs, the new adhesives are suitable for use up to 80°C and have a fixture time of less than 5 sec under UV light or 30 to 45 seconds in non UV flashed bondlines when used to bond steel and only 5 to 10 seconds for bonding ABS. Excess of product is cured rapidly in 20 to 60 secs by UV light achieving an excellent cosmetic appearance.

The unique combination of extremely high bond strength together with a rapid and complete cure, provides an ideal means of improving both the output and performance of many industrial bonding operations.

Suitable for a wide range of applications including the bonding of polycarbonate windows to ABS housings, tamper proofing and loudspeaker assemblies, their excellent cosmetic appearance makes them perfect for the bonding of logos and plastic parts in a wide range of industries wherever the adhesive is visible. They are also ideal for the manufacture of medical equipment and are biologically tested and approved to ISO 10993, for use in medical devices.

Henkel Loctite's new Light Curing instant adhesives couple the rapid light cure of an acrylic adhesive with a secondary cyanoacrylate cure, effectively combining the adhesion and shadow cure of standard instant adhesives in thin bondlines with the depth of cure and excess curing characteristics of UVs.

With the introduction of Light Curing Instant Adhesives, Henkel Loctite has provided a new range of options for the bonding of many types of materials in a wide variety of engineering applications.
