Shin-Etsu KE-4898 is a single-component, room-temperature curing, thixotropic silicone adhesive that forms a tough and durable elastomer. It is low odor, neutral cure, non-corrosive, and adheres strongly to metals, plastics, glass, and ceramics without primer. The formulation is stripped of low molecular weight siloxane and requires cold storage for stability.
