Low viscosity for quick wet out of synthetic
composite fabrics; especially effective with Kevlar
and carbon fiber.
Medium speed hardenerprovides up to 150 minutes
of pot life at 72 F (22 C).
Fire retardant system contains high levels of
phosphorous to reduce flame spread and smoke
generation in a composite laminate when compared
to a standard resin system.
Optimizedfor hand wet out and machine
impregnation in contact molding, vacuum bagging and
filament winding applications.
Room temperature cure properties suitable for many
composite components and structures.
T
gas high as 138 F (59 C) with proper post cure
providing excellent temperature stability and great part

Store PRO-SET Epoxy resins and hardeners at room temperature in sealed containers until shortly before use. As with many
high-performance epoxy resins, repeated exposure to low temperatures during storage may cause the resin to crystallize. If this
occurs, warm the resin to 125 F and stir to dissolve crystals. Hardeners may form carbamation when exposed to CO
2 and
moisture in the atmosphere for extended periods of time. Prevent carbamation by protecting hardeners from exposure until
immediately prior to processing.

EPIKO and EPIKURE Curing Agent MGS RIMH
Application
Low viscous infusion resin system for processing of woven and non-crimp multiaxial fabrics of low to high areal weight. Due to its very good
mechanical properties, this system is suitable for the production of components featuring high static and dynamic loadability and high heat
resistance.
Infusion resin RIMR 935 is based on bisphenol AF resin. Hardener RIMH 936 and RIMH 937 are a modification of aliphatic and cycloaliphatic
amines. Pot life (100 g mixed at 30 *C/86 F) is approximately 2 hours for RIMH 936 and 3,5 h for RIMH 937. Optimum viscosities for infusion are
tealized at temperatures in the range of 25 – 35 C (77 – 95 F). Pot life is then between approx. 1h (RIMH 936 at 40 C/104 F) to 5 h (RIMH 937
at 25 C/77 F). Following initial curing at room temperature, the parts are still brittle and require heat treatment at a min. temperature of 50
*C/122 F before processing or demoulding. Direct curing at elevated temperatures (60 C-100 C/140 *F-212 F) is possible. The curing time can
be reduced to a few minutes by this.
Non-tacky, high-gloss surfaces are obtained even with unfavourable curing conditions, such as low temperatures or high relative humidity.
The infusion resin system does not contain any unreactive components. All raw materials and additives feature a very low vapor pressure,
therefore permitting processing of the material under vacuum even at elevated temperatures. Compatibility problems are not to be expected in
combination with suitable geicoats, various paints (e.g., PUR-based), etc., however comprehensive tests are indispensable
These products can be stored for at least 24 months in their carefully sealed original containers. Even though it is unlikely, these products may
crystallise at temperatures below +15 C. The crystallisation is visible as a clouding or solidification of the contents of the container. If
crystallisation of either component should be observed, it can removed by warming up. Slow warming up to approx. 50 C-60 C (122 *F-140 F) in
a water bath or oven and stirring or shaking will clarify the contents of the container without any loss of quality. Use only completely transparent
products. Before warming up, open containers slightly to permit equalization of pressure. Caution during warm-up! Do not warm up over an open
flame! While stirring up, use safety equipment (gloves, eyeglasses, respirator equipment).
The relevant industrial safety regulations for the handling of epoxy resins and hardeners and our instructions for safe processing are to be
observed.

DENSITY
Rev 2 /Dec 2015 Test specimens were neat epoxy (without fiber reinforcement).
Typical values, not to be construed as specification.
Low viscosity for good wet out of all
synthetic composite fabrics and core
materials.
Slow cure hardener provides approximately
160 minutes of working time at 72 F (22 C). A
typical laminate will gel in about 4 to 5 hours
at 72 F (22 C).
Optimized for hand wet out and machine
impregnation in contact molding, vacuum
bagging and filament winding applications.
Room temperature cure properties suitable
for many composite components and
structures.
T
g as high as 172 F (78 C) with proper post
cure providing excellent temperature stability
and great part cosmetics.
Cost effective, high performance epoxy
formulation for synthetic composite
manufacturing.
Quality-control tinting is available at no extra
charge; simply add “QC” after the product
code on your order.
Shelf life is 3 years for resin and 2 years for
hardener when properly stored

Store PRO-SET Epoxy resins and hardeners at room temperature in sealed containers until shortly before use. As with many high-performance
epoxy resins, repeated exposure to low temperatures during storage may cause the resin to crystallize. If this occurs, warm the resin to 125 F
and stir to dissolve crystals. Hardeners may form carbamation when exposed to CO
2 and moisture in the atmosphere for extended periods of time.
Prevent carbamation by protecting hardeners from exposure until immediately prior to processing.

EPIKO and EPIKURE Curing Agent MGS RIMH
Application
Low viscous infusion resin system for processing of woven and non-crimp multiaxial fabrics of low to high areal weight. Due to its very good
mechanical properties, this system is suitable for the production of components featuring high static and dynamic loadability and high heat
resistance.
Infusion resin RIMR 935 is based on bisphenol AF resin. Hardener RIMH 936 and RIMH 937 are a modification of aliphatic and cycloaliphatic
amines. Pot life (100 g mixed at 30 *C/86 F) is approximately 2 hours for RIMH 936 and 3,5 h for RIMH 937. Optimum viscosities for infusion are
tealized at temperatures in the range of 25 – 35 C (77 – 95 F). Pot life is then between approx. 1h (RIMH 936 at 40 C/104 F) to 5 h (RIMH 937
at 25 C/77 F). Following initial curing at room temperature, the parts are still brittle and require heat treatment at a min. temperature of 50
*C/122 F before processing or demoulding. Direct curing at elevated temperatures (60 C-100 C/140 *F-212 F) is possible. The curing time can
be reduced to a few minutes by this.
Non-tacky, high-gloss surfaces are obtained even with unfavourable curing conditions, such as low temperatures or high relative humidity.
The infusion resin system does not contain any unreactive components. All raw materials and additives feature a very low vapor pressure,
therefore permitting processing of the material under vacuum even at elevated temperatures. Compatibility problems are not to be expected in
combination with suitable geicoats, various paints (e.g., PUR-based), etc., however comprehensive tests are indispensable
These products can be stored for at least 24 months in their carefully sealed original containers. Even though it is unlikely, these products may
crystallise at temperatures below +15 C. The crystallisation is visible as a clouding or solidification of the contents of the container. If
crystallisation of either component should be observed, it can removed by warming up. Slow warming up to approx. 50 C-60 C (122 *F-140 F) in
a water bath or oven and stirring or shaking will clarify the contents of the container without any loss of quality. Use only completely transparent
products. Before warming up, open containers slightly to permit equalization of pressure. Caution during warm-up! Do not warm up over an open
flame! While stirring up, use safety equipment (gloves, eyeglasses, respirator equipment).
The relevant industrial safety regulations for the handling of epoxy resins and hardeners and our instructions for safe processing are to be
observed.
