TYPICAL CURING PERFORMANCE

 

HEAT CURE 

Typical heat cure conditions consist of heating and maintaining bondline at a temperature given below

for the corresponding time specified. 

CP-7412 SR will commence curing upon exposure to temperatures above 80ºC. Adhesive volume,

heating temperature and duration will affect cure speed 

and adhesion. Optimum conditions for heat cure should be determined on the actual assemblies. 

 

Recommended Curing Conditions 

Bondline temperature, °C  : 125 

Heating duration, minutes  : 10 

Bondline temperature, °C  : 100 

Heating duration, minutes : 6.0
