Torque Retention Isolation
Torque Retention Isolation Sealing Solutions
TRI-Seal™ introduces rigid spheres into expandable sealant materials which are used to seal interfaces where faster load retention and/or separation of dissimilar materials are important.
What is TRI-Seal?
The unique solutions for torque retention, isolation and sealing all at the same time
Torque Retention Isolation Sealing Solutions (TRI-Seal™) is engineered to provide torque retention and isolation at interfaces where load retention and/or separation of dissimilar materials is important, and robust sealing against water, air and dust intrusion is required.
TRI-Seal™ is made up of non-conductive Alumina rigid spheres dispersed into L&L’s sealant materials. There are two different forms: dry-to-the touch and tacky. TRI-Seal™ dry-to-the-touch requires heat to activate the expandable sealant material. TRI-Seal™ tacky does not require heat and self-adheres to a mating surface. Torque retention is achieved by the clamp force between substrates being supported by the rigid Alumina spheres. The result, a unique product that is capable of torque retention, isolation, and sealing all at the same time.
The robust and lightweight sealing solution with maximum sealing coverage and anti-corrosion features.
In order to meet specific application requirements, we offer both dry and tacky solutions. For the dry to touch seal, the sealing material is thinner than the spheres to ensure the contact with the metal. For the tacky seal, a thicker seal can be achieved so that the material can flow under clamp load to ensure maximum sealing coverage.
