DELO brings light to the dark side 27 July 2016

DELO Industrial Adhesives LLC has introduced black adhesives, including the DELO-DUALBOND® GE4949, which are light curable and suitable for use in many applications.

For light curing processes adhesive needs to be translucent so that photoinitiators in the entire adhesive layer can decompose and start the crosslinking reaction. Because black absorbs the majority of light, the amount that is transmitted becomes naturally lower as the layer gets thicker.
However, the black dyed DELO-DUALBOND® GE4949 acrylate can be used for thicknesses of up to 500μm. In addition to its light curing component, it also contains a small humidity curing portion, which triggers crosslinking even in small shadowed areas.
The acrylate is medium viscous, has very good tension equalising characteristics — thanks to a high elongation at tear, and achieves high strength on various plastics. It is particularly suitable for sealing and bonding for black components. This includes sealing wires, covering lettering, bonding clips or emblems, as well as sealing connecting terminals.
