High elastic and flame retardant electronic silicone sealant
for the potting in LED,
power modules,
electronic vigour pieces
KY-907 High elastic and flame retardant electronic silicone encapsulation
1. product introduction
KY-907 can be divied two components and three components, which is a condensation-type potting material cured under room-temperature specially designed for the potting in LED, power modules, electronic vigour pieces, screen, and other electronic products.
2.Properties
excellent resistance to high and low temperature change, anti-uv, anti-aging properties,flame retardant and matt sex; faster overall curing speed, low viscosity and good softness, more suitable for perfusion; It also has excellent adhesive sex, and therefore has better sealing effection. effective moistureproof, waterproof; Can be used between the temperature -60 ~ + 250°C
