AssureCure™: When Confidence in Cure is Critical

A System to Quantifiably Measure the Degree of Cure of Adhesive Bonds

 

Henkel Corporation has introduced a revolutionary new technology designed to quantitatively and cost-effectively assess the degree of cure of light cure adhesives. A simple in-line process, the Loctite® AssureCure™ System includes new adhesive technology, fiber optic light sources, light detector unit, and software that ties into the user's PC or PLC.

Comparison to Existing Detection Methods 

Compared with alternative cure detection methods the AssureCure™ system provides the only reliable in-line, non-destructive method to confirm that the adhesive is cured.


Typical Applications:

Light cure adhesives are used to bond and seal devices in a wide range of industries from medical devices to electronic and optical components.

The advantages of very rapid cure rates, excellent adhesion to many materials and the ability to fill large gaps allows manufacturers to accelerate their production processes while producing aesthetically pleasing, clear bond lines.

How They Cure

All liquid light cure adhesives contain photoinitiators which are shown as double red spheres. When the liquid adhesive is exposed to light of an appropriate wavelength and intensity the photoinitiators absorb the light energy and fragment into reactive free radicals. These free radicals react with the monomers, shown as single white spheres, initiating an extremely rapid polymerization process.
