Heat-curing adhesives are used in many applications that require high strength and permanent resistance to environmental influences. In order to achieve these properties, the adhesive is cured at temperatures between 100 °C and 150 °C in most cases. DELO Industrial Adhesives has developed a special adhesive for temperature-sensitive parts that gives full strength even at a curing temperature 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.
DELO is a leading manufacturer of industrial adhesives with its headquarters in Windach near Munich, Germany, and subsidiaries in the USA, China and Singapore. In the fiscal year 2014, 400 employees generated sales revenues of nearly EUR 60 million. The company supplies customized special adhesives and associated technology for high-tech industries such as automotive, aviation, optoelectronics, and electronics. DELO’s customers include Bosch, Daimler, Festo, Infineon, Knowles and Siemens. DELO won the German Industry’s Innovation Award 2014.
