Automotive radar potting sealant solution
Automotive radar sensors belong to a class of high grade precision sensors. They work in very harsh environments and need to meet the requirements of waterproof, seismic and high temperature resistance. The automotive radar potting sealant produced by BTL is a two-component and formed liquid potting silicone rubber, which has the characteristics of fast curing speed, equal artware flow, good adhesion to PC and nylon material, and shows excellent weather resistance in practical application.
