Dynatex® Blue RTV Silicone Gasket Maker is a paste-like, one-component material, which cures to a tough, rubbery solid upon exposure to moisture in the air. It has a good resistance to weathering, vibration, moisture, ozone and extreme temperatures. It also, resists oil, water, anti-freeze and transmission fluid while withstanding the harsh conditions of gear oil, especially with differentials and transfer cases.
