Coatings

Fiber-type laminates are often coated with an anti-stick coating to improve both fluid sealing and the release properties from the flanges upon teardown of the joint. MTI offers our TechCoat product line for this purpose. These water-based coatings can be applied to sheets or finished parts and are specially designed to accept a silicone bead in these types of applications.
