What is ocr optical resin?

OCR optical transparent resin is a special adhesive for bonding transparent optical elements. It can fill the gap between the panel, the transparent protective layer and the liquid crystal module to improve the contrast of the display. Compared with the traditional method using air gap, this optical resin can suppress light scattering caused by external illumination and backlight. The optically transparent resin formed by rapid reaction under ultraviolet irradiation has a refractive index and light transmittance similar to that of glass, is resistant to yellowing and soft, and can withstand the expansion and contraction of various substrates, thus resisting the problems caused by high and low temperature changes during bonding. This product is suitable for bonding and assembling touch screens, large-size glass substrates or other soft and hard boards.

Characteristics of OCR optical resin products

◇ Curing mode: UV curing combining point light source and surface light source;

◇ chemical system: acid-free colloid, compatible with ITO;

Ease of use: you can choose dispensing or other corresponding coating methods;

◇ Repairability: characterized by rework before it is completely cured;

◇ Optical characteristics: high light penetration characteristics, refractive index matching;

Other characteristics: low hardness, low shrinkage and low haze.

Especially suitable for bonding large-size glass substrates or other hard plates, characterized by ITO compatibility and rework. Curing method: UV curing is acid-free colloid with ITO compatibility, machinability and ease of use: it can be coated by dispensing or other coating methods with high light penetration characteristics, which can improve the impact resistance of glass substrate.
