EP254

EP254 is a low temperature curing, toughened epoxy that cures in the 235ºF to 275ºF range.  Glass prepregs can co-laminate to carbon/epoxy prepregs without shear failure.  EP254 is the most post formable composite prepreg system available today. 

EP255

EP255 is a low temperature curing toughened epoxy that cures in the 235ºF to 275ºF range.  It is self-adhesive to aramid honeycomb and can be used for a wide variety of structural applications.  It is self-extinguishing, passing the 60 second vertical ignition test listed in FAR 25.853. 

EP255N

EP255N is a variant of the EP255 system with increased mechanical performance over EP255. EP255N is a modified epoxy that is cured in the 235 to 275ºF temperature range. It is self-adhesive to aramid and aluminum honeycomb. EP255N exhibits excellent strength properties and can be used for a wide variety of structural and aerospace applications. EP255N meets the requirements of MIL-R-9300B, type 1. EP255N has excellent resistance to ethylene glycol, hydrocarbon fluids and oils, Skydrol@ and water.

EP255 Film Adhesive

Based on the EP255 epoxy prepreg resin system, this supported film adhesive is designed for use in a variety of bonding applications such as metal to metal, composite to core or metal to core.  Sandwich constructions include aramid, aluminum and various foams.

EF5A

EF5A is a 350ºF curing epoxy resin system formulated to produce laminates with good mechanical and electrical properties at elevated service temperatures.  This system is flame retardant and exhibits good hot/wet properties.  EF5 is a variant of EF5A specifically designed for use in radomes.

EL314

EL314 is a 350ºF curing epoxy that is used in high temperature electrical and structural applications.

FM-2

FM-2 polyester prepregs are designed for low pressure laminating at 250ºF to 325ºF.  Developed to render precise and controlled flow, these light to medium tack prepregs provide excellent flexural strength characteristics and structural integrity.

FM-5

FM5 is a toughened polyester system designed for table rolling applications such as fishing rods,
antennae radomes and kayak paddle shafts. It offers precisely controlled flow, excellent resistance
to bending set and extremely high flexural strength making it ideal for dynamic, low frequency applications.

LC173

LC173 polyester prepregs are designed for low pressure laminating at 265ºf to 325ºF.  LC173 prepregs provide high fire resistance properties.
