PRF Composite Materials RS-M135
- Chemical Family
- Epoxy & Epoxy Derivatives
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.

- Storage
The hardeners can be stored for a minimum of 12 month in original, sealed containers at 15 - 25°C. Crystallization of these materials may occur at temperatures below 15°C and is visible as a clouding or solidification of the liquid within the container. Before processing, the crystallization must be removed. This can be done, without any degradation to the product, by slowly warming the material to approximately 50 - 60°C in a water bath or oven and stirring or mixing until the liquid becomes clear.
- Introduction
There are 2 hardeners varying in reactivity, with pot lives from 20 -30 minutes up to 4 hours. The individual hardeners can be inter-mixed in any ratio, enabling users to optimize the pot life of the system to meet their individual requirements. Cured parts can be worked and demoulded after curing at room temperature. Due to the low vapor pressure of the raw materials, this system can be processed at the elevated temperatures (80 - 100°C) using vacuum processes for example, vacuum assisted RTM. However the maximum temperature will depend on the layer thickness and the geometry of the component part. Adding an internal parting agent, e.g. zinc stearate, has proven useful for pultrusion processes where profiles with good surface finishes have been produced. Depending on the profile geometry, mold temperatures in the range of 180 - 230°C are possible, thus permitting higher drawing speeds. It is not expected that there should be compatibility problems with fully cured, dry UP gelcoats or various paint systems (e.g. PUR-based), etc. However, comprehensive tests should be carried out first to confirm this. The resin and hardeners in this system contain neither solvents nor fillers. Careful selection of raw materials has ensured this system is low in odor and has good physiological properties, minimizing skin irritation and allergy problems. However, the appropriate safety advice regarding contact with, and processing of, epoxy resin system should be followed.
