Rubber adhesives offer high initial strength and are adequate for short term, non-critical applications. They have limited chemical, temperature and ultra violet light resistance. Silicone adhesives are used for high temperature and bond well to silicone keypad applications. The primary advantages of acrylic adhesives are: long life, ultimate adhesion, great for outdoor and high performance, adhere well to most surfaces, outstanding chemical, solvent, and ultra violet resistance. Based on the overall superior performance characteristics of acrylic PSAs, this module will focus on acrylic.
