Designed for superior sealing and gasketing applications, it offers excellent adhesion and flexibility. This 100ml tube provides robust resistance to engine oils, coolants, and transmission fluids, making it ideal for sealing oil pans, valve covers, timing gear covers, and differential covers. It withstands continuous temperatures from -55°C to +200°C (with intermittent exposure up to +250°C) and cures by moisture exposure to form a durable, flexible seal.
