9002GA(9600Q)/9002GB(9600Q)Filled Heat Cure Epoxy Casting Resin System
for automotive ignition coil

Description

l  9002GA(9600Q)/9002GB(9600Q) is a filled, heat cure two part epoxy casting resin system.

l  9002GA(9600Q)/9002GB(9600Q) is recommended for casting of ignition coil for automobile.

l  9002GA(9600Q)/9002GB(9600Q) offers low filler sedimentation and good thermal resistance.

l  Excellent and electrical properties.

Application

(Mix)     Prior to mix, agitate homogeneously each materials, 9002GA(9600Q) and 9002GB(9600Q)B, in the container.

 Then mix 9002GA(9600Q) and 9002GB(9600Q) completely at proper mix ratio.

 

(Cure)    Recommended cure:

2.5 hours at 90℃ plus 2.5 hours at 130℃

Storage and handling

 

Keep each materials in closed package in cool and dark place.

9002GA(9600Q)/9002GB(9600Q) resin system may cause skin irritation, void skin contract.

If contract occurs, wash with soap and water at first opportunity.
