Latest Patents

Koev's latest patents include a dip coating process for optical elements. This innovative process provides a coating on the surfaces of an optical element with more consistent coating thickness. The method involves holding the coated optical element in a way that creates a meniscus between the element and the coating solution. This positioning allows the capillary force generated by the meniscus to drain excessive coating, resulting in a uniform thickness across the surface. Another significant patent is for controlled tintability on mar-resistant coatings. This invention addresses the challenge of providing abrasion-resistant coatings that maintain good coatability and optical clarity while allowing for tinting after application. The coating composition includes a solvent, an epoxy resin composition, and an aminosilane, which together form a durable and tintable abrasion-resistant coating.
