Online application – just one step away. When producing sealing profiles for door seals or trunks containing butyl, the butyl is often added in an offline, separate production step. The VarioProof® product innovation developed by SaarGummi Automotive saves this additional step because the permanently elastic sealant is added to the sealing profile during extrusion process. It adapts to small changes of the body in white, is odorless and can be used in a temperature range typically requested.
