The coating process involves a 100% solid system. Coated products made out of this liquid rubber on SAE 1008 steel, have been tested for gasket applications.

In order to seal a fluid, it is necessary to design the rubber coating and the contact pressure with consideration of the surface roughness. In this study, leak tests are conducted with the softmetal, and the effects of contact conditions, such as surface roughness, load, rubber thickness and rubber material are investigated.

This paper discusses gasket technology to address the increasing demands of providing effective sealing solutions for exhaust systems. Increasingly, effectively sealed joints are required in exhaust systems to meet environmental and emissions regulations. These applications are especially demanding for sealing. With low load joints, significant flange movement, and temperatures in excess of 850°C (1550°F), it is difficult for traditional gaskets to provide an effective seal, typically degrading or creeping at operating temperatures. Utilizing multi-layer steel gasket technology, this paper details a solution to these problems. Temperature stability and sealing data is presented demonstrating the superior performance of this material. Also presented is information from recent field experience.

Sealing these various hardware surface finishes is accomplished via a rubber on the surface. The coating's ability to conform to various surface irregularities while withstanding high temperatures, long term coolant and oil exposure, and joint shearing forces is paramount to long term sealing. ...This paper will explore the sealing capabilities of a highly conformable flouro-polymer rubber coating developed specifically to seal rougher surface finishes.

This paper introduces a coating that has both excellent temperature stability and good compliance, thus forming an excellent sealing enhancement for metallic layers in exhaust system gaskets.
