Enhanced Flexible Hard Coat with UV Blocking Description FleXHC-UV is a siloxane polymer solution designed for plastic substrates. It is a truly flexible hard coat which is highly effective at blocking ultraviolet (UV) radiation. FleXHC-UV combines excellent optical and mechanical properties with great resistance to various chemicals. FleXHC-UV is recommended for outdoor applications where UV exposure typically causes yellowing, print fade and overall material degradation. As a film, FleXHC-UV can be applied to windows where it can block 99% of harmful UV light, making it ideal for shops, museums and other display areas. Key features of FleXHC-UV - Scratch resistant - Easy-to-clean - smudge resistant - Retention of UV blocking capability for at least 5 years in outdoor applications - Superior durability in outdoor applications - Excellent visual outlook - Truly flexible and bendable - Glass-like surface - Provides superior abrasion, humidity and solvent resistance 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 stable coating performance achieved. R2R processing enables coating in high volumes whereas sheet processing is easily setup for small series production and R&D purposes. Solution properties, storage and handling When purchased as a solution, the solution should be stored in a well-ventilated place. Keep containers tightly closed and protected from sources of heat and light. For working safety, consult product Material Safety Data Sheet. Coated products We also provide coated PET rolls with Optitune Flex-materials, see information contacts below.
