Optics Coating Applications

We offer optically clear thermal and UV-cure hard coatings with premium abrasion resistance for optics.

Our solutions are UV resistant; they will not haze or discolor with exposure to sunlight. And they help conserve energy, as protection from ultraviolet rays results in lower temperature variances required for heating and cooling.

They are also resistant to oil, dirt, and corrosion and are easy to clean and maintain with common household ammonia-free glass cleaners.

Our subsidiary COTEC GmbH also offers coatings with easy to clean properties for precision optics; as well as hydrophobic and weather resistant protective features for special optics applications used for a variety of industries such as medical imaging, heads up displays for aerospace/defense and automotive, to commercial and industrial security motion cameras. Additionally, COTEC supplies standard coating materials for optics applications industries such as high purity optical filter materials.

Our solutions support the most demanding optical applications.
