New Adhesive from DELO Cures at Temperatures as Low as 60°C

An application area where many temperature-sensitive materials are used is optical packaging. In this industry, components are bonded to mini-cameras, actuators and infrared, image or motion sensors for consumer electronics. The micro-optics of these assemblies are often covered by anti-reflection or filter coatings. Unlike most plastic lenses, these coatings are very sensitive and get damaged at elevated temperatures. The new DELOMONOPOX LT204 epoxy resin now makes it possible to bond these materials without any problems.

Easy and economical processing

This multi-purpose, one component adhesive can be processed within 48 hours at room temperature and has excellent adhesion to many plastics, including LCP, PA and PPS, as well as to metals and FR4 composites. It can be dispensed through needles with a diameter as small as 200 µm, which are common in consumer electronics and enable finest structures. Curing is possible from 60 °C, minimizing the thermal stress and resulting in reduced warpage of the components bonded and fewer tensions within the package. In addition, DELO''s new adhesive helps the bonding process excel through low energy consumption and high profitability.
