SCA Optical Glue Optical Performance and Tint Meter

SCA optical glue is simply a thermosetting glue. The characteristic of this kind of glue is that it will be cured under the condition of continuous heating. It has excellent light transmittance, clarity and adhesion. However, such products generally require high light transmittance, UV blocking and high infrared blocking characteristics. Tint meter is recommended to measure the visible light transmittance, UV rejection rate and IR rejection rate.

SCA optical adhesives are widely used, they can be applied to industries such as smart home, medical electronic applications, automotive military, full-fit applications, outdoor product applications and education applications. Therefore, they have different requirements on the visible light transmittance, the UV and IR rejection rate. SCA optical glue is widely used in outdoor products and education products.

The biggest feature of outdoor products is the aging, anti-vibration and explosion-proof performance of electronic components. So it is generally suitable to use SCA-TR optical glue. The use environment determines the characteristics of this glue are high light transmittance, high UV rejection rate and infrared rejection rate. Generally, the UV rejection rate and the infrared rejection rate is 55%-75% measured with a tint meter.

As educational products are generally used by students, SCA-AL optical glue is generally recommended. This kind of optical glue generally requires high light transmittance and high UV rejection rate and good anti-blue light effect. Generally, the blue light rejection rate is 50%-85%. The blue light blocking wavelength is 400nm-440nm. The UV rejection rate is greater than 90% and the blocking wavelength is 360nm-400nm.
