Abstract
A resin for making abrasion and scratch resistant UV blocking glass coating. The resin can include an inorganic polysiloxane polymer matrix formed from water-based colloidal silica and tetraethylorthosilicate (TEOS). The resin also can include a bi-functional silanol coupling agent coupled to the inorganic polysiloxane polymer matrix. The resin further can include a UV absorber conjugated to the bi-functional silanol coupling agent. The resin also can include a solvent that is compatible with the colloidal silica, TEOS, bi-functional silanol agent, and UV absorber.
