Advantages of TAC-ON™ coating for glass lens mold

Nanofilm have already established themselves for quite a few years in the glass and plastic lens mold coating industry with our TAC-ON™ protective films, with many well-known lens manufacturers gradually applying this type of coating to their product. This gradually replaced traditional DLC coating and precious metal coatings that were previously in use. It is especially obvious in the manufacturing of large scale, wide-angle professional glass lens molds for professional cameras. The 100nm TAC-ON™ film have been widely promoted and accepted by customers with positive reviews.

◾ Excellent anti-corrosion properties

◾ Thin but strong film with low wear rate and coefficient of friction

◾ Remarkable adhesion properties

◾ Excellent anti-stick properties, molded product easy to remove

◾ Hydrogen free, suitable for applications under elevated working temperatures with no oxygen present

◾ Pure carbon coating film does without any form of oxide or metal. TAC-ON™ film can be easily de-coated and re-coated, and the newly coated mold can be reused

◾ Guaranteed long-term production usage with dimensional accuracy

◾ Increased lifespan, as compared to DLC coating:

 For small diameter and small radius-of-curvature molds, TAC-ON™ is capable of increasing the lifespan by 3 times or above. For large diameter and large radius-of-curvature molds, TAC-ON™ is capable of increasing the lifespan by 5 times or above.
