Henkel Loctite Adhesives Ltd announces 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 heat or the need for racks to cure products over a long period (Plate 5).

 Plate 5Loctite 4304 low viscosity, and Loctite 4305 high viscosity adhesives, are supplied as 28 g or 454 g packs

Supplied as 28 g or 454 g packs, the new adhesives are suitable for use up to 80°C and have a fixture time of 30-45 s when used to bond steel and only 5-10 s for bonding ABS.

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. 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 cure of standard instant adhesives with the depth of cure and surface 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.
