Poly Epoxy is a true high-performance epoxy resin with unmatched tensile, compressive, and flex strengths. It also has unbeatable peel, shear, and fatigue resistance, as well as impact strength and fracture behavior. Its great for wings, canards, fuselages, tail feathers, and landing gear.
Use it in molds or
moldless construction. It parts easily and works beautifully in vacuum
bagging. (Avoid silicone-treated peel ply.) It has TWO cure phases, while
all other resins-epoxy, polyester, or vinylester-have just one. The two
phases occur all by themselves during the curing process. The resulting
bond is tougher and stronger than any other. |
