Title: The Innovations of William C. Harbison
Introduction
William C. Harbison is a notable inventor based in Lake Forest, California. He has made significant contributions to the field of materials science, particularly in the development of impact-resistant laminates and abrasion-resistant coatings. With a total of three patents to his name, Harbison's work showcases his innovative approach to solving complex engineering challenges.
Latest Patents
One of Harbison's latest patents is for an impact-resistant laminate. This laminate features a transparent design that includes a special urethane-modified acrylic sheet. This sheet contains a vinyl-functional polyurethane elastomer, which is a polymerization product of an aliphatic diisocyanate, hydroxyl-functional polyether or polyester prepolymers, and a hydroxyl or amine-functional vinyl monomer. In a three-ply embodiment, the urethane-modified acrylic sheet serves as the back ply, while a hard plastic sheet, such as cast acrylic, forms the front ply. An intermediate ply made of a thin, high-elongation material like polyurethane is also included. In a more complex five-ply embodiment, the laminate incorporates an additional thin sheet with high elongation behind the urethane-modified acrylic ply, along with a ductile plastic sheet made of polycarbonate as the back ply.
Another significant patent by Harbison is for a coated substrate comprising a cured transparent abrasion-resistant coating. This coating is applied to at least one surface of a substrate and consists of a colloidal dispersion containing colloidal antimony oxide and colloidal silica in a weight ratio of less than or equal to about 30:70. The coating is formulated in a water-alcohol solution of the partial condensate of R(Si(OH).sub.3), where R represents an organic radical.
