excellent electrical performance

KJR series are polyimide silicones, which stabilize the PN junction surface, minimize leakage current, have good electrical properties over a wide frequency range, and provide a stable electrical environment for LED devices.

High heat resistance

the series has excellent heat resistance, such as models such as the KJR-651, which can maintain stable performance in temperatures ranging from -50°C to 300°C, and can withstand the high temperatures generated by LED operation, ensuring that the device operates properly in high-temperature environments.

good optical performance

LPS series in Shin-Etsu's KJR series is a highly transparent silicon encapsulation material with high transparency that meets the requirements such as high refractive indexing required for LED applications, contributing to improving the light output efficiency and optical performance of LEDs.

high adhesion

KJR series has high adhesion to a wide range of substrates and is able to adhere securely to the surface of LED devices, ensuring a reliable connection between the coating and the device that does not fall off easily, thereby improving device reliability.

low ionic impurities

KJR series products have very low ionic impurity content and high material purity, which can provide excellent stability for various semiconductor devices and reduce performance degradation or failure problems caused by impurities.

this series of products is available in a variety of hardness and modulus, such as Shore A 80 for the KJR9080 series, Shore A 30 for KJR9080S-12 hardness, and Shore D 6 for KJR9086-2X hardness, etc., which can meet the requirements of different application scenarios for material mechanical properties.
