Synergy Glass Coating is a super hydrophobic nano ceramic coating specifically designed for glass. This high tech coating creates an extremely hard, slick, clear barrier of protection on exterior glass surfaces. Synergy chemically bonds by penetrating the top surface of the glass, increasing the contact angle of the glass surface and water. This super hydrophobic surface increases water repellency, causing water to bead and easily sheet off the glass. Available in 50ml size. VOC COMPLIANT.
