Finished Adhesives and Sealants

UV LED curing refers to a technique that uses “energy” output from the light emitting diodes (LEDs) in the ultraviolet (UV) spectrum to treat coatings, adhesives, inks and other UV-curable materials.

Fourteen tubes of polyurethane sealant and an older suburban Western Pennsylvania home made for a perfect fit to seal in noteworthy energy savings.

 One never gets a full 100% cure of these thermoset systems at relatively low temperatures because molecular mobility goes down dramatically as the adhesive increases in viscosity during curing.
