G-83CM PREPREG SYSTEM
G-83CM resin system provides a quick cure (290°F for 20min) or a low temperature cure (185°F for 6 hours) with thecapability to achieve class “A” surface finish. This system works
well for both autoclave and fast cycle press mold processes.
Quick cure cycles are used where high-cycle applications arerequired; lower temperature cure applications would be used
where mold material is heat sensitive. G-83CM is a provensystem in the automotive industry due to its fast cure and highquality Class A capability. This system works well in a varietyof other applications such as industrial and aircraft gradeHigh Heat Tolerance
High Tg allows for high temperaturepart demolding reducing cycle
time. Material works well with hightemperature paint curing cycles.

Easy Layup
Product allows complex part layupwith minimal cuts or ridge lines.
It maintains a comparable class A
finish through post-cure, minimizing
sanding and finishing times.

Readily Available
Product is in stock and ready to ship.

Flexible Cure Methods
Cutting methods include autoclave,oven cure, or press molding. Productcan be cured with or without using adwell.

Availability:
G-83CM resin is available with numerous types of unidirectional carbon fibers and woven and glass fabrics
with Fiber Areal Weight (FAW) ranging from 70 g/m2 to 300 g/m2 and Resin Content, (RC%) by weight percent,ranging from 24% to 44%.
