Durable Easy Clean Hard Coat for Plastic Surfaces

From foldable touch screens to autonomous driving sensors; FleXHC provides the highest levels of light transmission, abrasion resistance, flexibility, optical clarity and cleanability. FleXHC is a siloxane polymer solution designed for plastic substrates. FleXHC is available as a coated PET-film, and as a liquid ready-to-coat solution. FleXHC forms highly transparent, optically clear and flexible hard coating on substrates like PET films. The coating is scratch resistant, easy to clean and has excellent optical properties. FleXHC is ideal for touch screen applications.

Technical Background

Plastics are everywhere due to their light weight and design flexibility. However, most of the commonly used plastics tend to scratch very easily and are susceptible to degrading by various chemicals. Optitune’s flexible hard coats can vastly improve these issues observed in plastics without sacrificing their flexibility or optical properties.

How to Apply

The solution is applied as a single-layer coating by using roll-to-roll (R2R) or sheet coating process followed by thermal and UV curing steps. Coating can be carried out using slot/die, gravure, reverse gravure, bar or other means of coating. After final curing, a stabile coating performance is achieved. R2R processing enables coating in high volumes whereas sheet processing is easily set up for small series production and R&D purposes.
