TECH LINE exhaust system coatings are designed to maintain adhesion at temperatures above the normal operating range of an exhaust system. Unless otherwise indicated, temperatures given refer to the base metal temperature that a coating can normally be expected to handle. Depending on the resin system, Tech Line’s coatings designed for exhaust systems, can handle base metal temperatures in excess of 2000°F. Color change can be expected at lower temperatures with many of the coatings. A color change does not necessarily reflect a failure of the coating, as color stability is secondary to the protective function. Several colors have maintained color stability to base metal temperatures in excess of 1600°F. The application of a base coat can raise the color stability of all exhaust system coatings.
