This grey premium sealant is an acetate-free agent with fantastic oil resistance that has been specially developed for oil sumps and crankcases, among other things. It has been tested at Porsche, among other places. It is also suitable as a replacement gasket on engine parts such as transmission covers, valve covers, differential gears and water pumps. Thanks to its heat resistance up to 250 °C and superb adhesion properties, it is perfect for many different surfaces, even without a primer, such as aluminum, most other metals, polymer-free plastics such as carbonate plastic, polyester, hard styrene plastic, ABS plastic and most hard PVC plastics. A Pressure Pack makes it easy to get the right amount of sealant. After application, the silicone reacts with the humidity in the air and creates a durable rubber. MPM Premium Gasket Sealant cannot be painted over and is also not suitable for surfaces made of ethylene plastic (polyethylene), Teflon or polypropylene.
