Description
UV LOCA TP-2500F (Liquid Optical Clear Adhesive) Glue (50 g) it's high quality of LOCA glue dedicated for LCD and Touch screen connetion. Higher resolution and greater contrast ratio is required in modern TP-LCD application such mobile phones and flat panel computers. The traditional OCA tape cannot fulfill the needs now due to the refractive index of OCA tape didn't quite match the TP and LCD glass, and therefore reduce the viewability under sunlight as the light reflected and the durability of OCA tape is poor. Solution it's LOCA !
Advantages of LOCA: - LOCA offer suitable refractive index (1.51) and can greatly increase the brightness and contrast ratio compare to OCA tape. - The application is a fast and reliable process compare to OCA tape. - It is UV curable and it provide excellent weatherability and hydrolytic stability, and this increase the lifetime of TP-LCD. - The process is fully automatic and the field is very high.
