Marsh Industries has nine pneumatic bonding presses using a hot vulcanization process to provided bonded rings and custom gaskets from either standard or custom cross-sectional profiles. Marsh Industries uses catalyzed compound to bond the gaskets endless, which makes for a much more durable splice compared to standard RTV bonding.
The compound is typically the same color and compound that is used in the cross section. The result is a bond strength that exceed conventional bonding processes. Using the bonding process, Marsh Industries, Inc. is able to offer a cost-effective solution for sealing applications. In addition, not only does bonding the seals allow for the ability to have hollow profiles, but also offers a solution to the seals that cannot be molded.
