MicroPhase manufactures a line of hydrophobic coatings that can be used on glass, stainless steel, and aluminum. On glass, the contact angles are 108 to 120 degrees depending on the application method. The coatings have excellent chemical resistance (pH of 0.5 to 13.5) and abrasion resistance. The products are used on shower glass, building glass, and car windshields to improve visibility and reduce water spotting and hard water build up.
