G-85FR PREPREG SYSTEM
G-85FR is a new resin system developed specifically to meetthe needs of the automotive industry. A 30 minute curetime at 325°F makes it suitable for high throughput
processes, and its flame retardancy and high heat tolerance
make it ideal for racing applications. This system also offers
easy handleability, and the capability to achieve a class “A”
surface finish.

Flame Retardant
Flame retardant material without
filler allows for maximum
mechanical performance. Material iscompliant to SFI specification 56.1
flammability testing at single plythickness. Meets UL94 V-0.
High Heat Tolerance
High Tg allows for high temperaturepart demolding reducing cycle time.
Material works well with hightemperature paint curing cycles.

Readily Available
Product is in stock and ready to ship.

Resin Chemistry
A latency time of 0.5 to 3 minutes
allows resin to flow through a partwithout reaching the gel point.

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.
Flexible Cure Methods
Curing methods include autoclave,oven cure, or press molding.
Product can be cured from 250 °F to325 °F depending upon toolingcapability.

Availability:
G-85FR resin is available with numerous types of unidirectional carbon fibers, woven, Aramid and glass
fabrics with Fiber Areal Weight (FAW) ranging from 70 g/m2 to 665g/m2 and Resin Content, (RC%) by weightpercent, ranging from 24% to 44%.
