Liquid silicone rubber of the ELASTOSIL LR 3078/40 US A/B is a paste-like, easilypigmentable two-component compound with extremely short curing times. 

The individual surface properties each substrate must be tested before mass production. If necessary, check the development of adhesive properties over time and/or in an environment relevant to the application.ELASTOSIL LR 3078/40 US A/B is noted for its’ ability to be molded into intricatelyshaped,precision parts. Very brief molding cycles for intricately-shaped and flashfree parts are possible.
