How does the FS 90 Laminex coating compare to that used by other companies?
The Laminex coating is a specialized thermally fused epoxy coating designed as a shedding / non-stick surface. Contegra tested dozens of coatings, including several Teflon formulations, and found Laminex to be an excellent non-stick coating. US Filter/Control Systems uses a Teflon formulation called Silverstone (both trademarks of Dupont). The two advantages of Teflon are 1) it is chemically inert, and 2) when used in cooking applications the Silverstone stains less than Laminex (reference www.silverstone.com for further information on Silverstone’s cooking applications.). The Laminex epoxy coating is also chemically resistant and has shown a superior ability to shed materials fast.
