PRF Composite Materials RS-M135 is an ultra low viscosity laminating system formulated for use in the manufacture of composite components from glass, carbon and aramid fibers. The system is suitable for components requiring high static and fatigue strength properties using injectin molding (e.g. RTM), vacuum infusion and pultrusion processes. At 25°C the mixed viscosity is approximately 200 mPa s and may be lowered further to a value of 100 - 150 mPa s by warming the resin (see page 5), thus even complicated parts with long flow paths can be injected without difficulty. With a mold temperature of around 30°C, the temperature rise with hardener RS-MH137 remains very slight, allowing thicker parts to be built at elevated temperatures.

PRF Composite Materials RS-L135 exhibits good mechanical properties after curing at room temperature. If high temperature strength is not required, finished products made with the selection of hardeners up to RS-H136 may be used without further heat treatment. Post curing (heat treatment) will further enhance the mechanical properties and will also increase the heat resistance.

PRF Composite Materials RS-L285 has very low mixed viscosity, ensuring a fast and complete impregnation of reinforcement fibers without drainage on vertical surfaces. The addition of fillers such as colloidal silica, microballoons, metal powder etc., is also acceptable to obtain special properties. The RS-L285 epoxy resin system exhibits good mechanical properties after curing at room temperature. If high temperature strength (≥ +60°C) or aircraft approval is not required, finished products made with the selection of hardener RS-H285 may be used without further heat treatment. Post curing (heat treatment) will further enhance the mechanical properties and will also increase the high temperature strength, up to 100°C being achievable depending on the selected hardener and post cure cycle used. The properties indicated in this document may only be achieved by curing/post-curing above 50°C.
