1 Bonding electrical and Araldite electronic adhesives components Build, structure, assemble a circuit board Encapsulate, insulate and bond electrical/electronic components

2 Bonding electrical and Araldite electronic adhesives components adhesives are high-strength materials formulated for use in a broad range of applications. Many of the adhesives are UL-recognized for high-temperature use and exhibit good dielectric characteristics as well as excellent chemical and moisture resistance. In addition, the products are easy to handle with a range of work lives and the ability to cure at room and elevated temperatures. The durable adhesives are sag resistant, resist shrinkage and are easy to apply from dualbarrel cartridges or via automated mixing/dispensing equipment. Broad range of work lives and cure schedules UL-recognized for high-temperature applications Good mechanical, environmental and dielectric properties
