Resulting Properties
A major application area for this sealant formulation is the auto industry and other areas. It is used in applications where compound adhesion is critical and large amounts of plasticizer must be avoided.
Liquid natural rubber can be used because of its reactivity. Once cured, it will not migrate over time as typical oils do.
