| JG-880A/B epoxy resin embedding material
JG-880A/B epoxy resin is LED encapsulating epoxy resin with high
light transmission rate, better workmanship and electrical performance,
being an ideal for encapsulation of high light transmission substances.
- Features
Low viscosity and excellent deairing performance
Wide range of reaction temperature (110-150¡æ), applicable for application
of multiple workmanships;
Smooth prophase reaction, low stress of heat contraction, and high
reliability of encapsulated products;
Extremely good light transmission rate of encapsulated products.

Pre-heat JG-880A to 40-50¡æ prior to use and add in JG-880B as per
proportion. Stir uniformly after being mixed up.
The mixture(A+B)is to be vacuum deaired under the condition of 3
to or/40¡æ. Stop deairing when the liquid surface is seen settled
for 10-15min.
Dripping glue is recommend for embedment under vacuum condition.
