Health and Safety instant adhesives

With successive introductions to its Loctite® Health and Safety range, Henkel has broken new ground. It has become the only manufacturer to offer a comprehensive range of non-hazardous engineering adhesives that cover the lion’s share of applications.

Now there is even more choice, however, as this unique range is complemented by three hazard-label-free cyanoacrylates, more commonly known as instant adhesives.

Clean and easy to apply, these adhesives are ideal where aesthetics are important. They are now the Loctite® front-line offering for very fast positioning and fixturing of parts. Classified non-irritant, these new additions provide even more benefits than their hazard-labelled forerunners.

Their ability to join a wide variety of dissimilar materials extends to the bonding of porous/acidic substrates such as wood, paper, leather and cork as well as plastics, rubber and metals. The resultant shear and tensile bond strength is excellent even on very small bond faces.

These new Health and Safety instant adhesives are colourless with low bloom and low odour. All have a typical fixture time of 5-20sec dependant on the substrates.

As with all Loctite® instant adhesives, these three new Health and Safety products are respectively optimised for specific application requirements. The most viscous is Loctite® 403, making it ideal for use where parts are not close fitting or where the product must not run or migrate.

Loctite® 408 has very low viscosity and comes into its own where capillary action is required. It can therefore be applied to a joint with an interference fit to create an instant seal. Loctite® 460 has a marginally higher viscosity.

All can be integrated into semi- or fully-automated production processes for which Henkel also markets a comprehensive range of dispensing equipment.

For applications where special application characteristics are required, Henkel can call on its wider range of instant adhesives. As well as products for difficult to bond rubbers and plastics such as PE, PP, PTFE and silicone, the choices include a new product for gap filling and a new series for high temperature applications.
