Epotec Systems for Wind Energy Applications
Tooling Resin SystemsEpotec® Tooling Systems allow manufacturing of customized tools for specific uses and include systems suitable for hand lamination as well as infusion process. Low curing shrinkage enables manufacturing of precise composite tools in most com-plex shapes quickly and easily. The tools offer low thermal expansion and provide excellent strength to weight ratio.
Versatile to di�erent processes and blade designs.Provide optimum combination of properties under static & dynamic loading conditions. Robust systems Designed to manage process and environmental variations.
Epotec® Resin for Infusion/ VARTM provide low initial viscosity and reactivity varying from few minutes to several hours at ambient temperature. The choice can be made depending on process conditions, geometry of the component and end use requirements. The systems can be used in combination with variety of reinforcements and core materials to make high strength structural components for sporting goods, marine, aeronautics, automobiles, wind energy applications.
Resin Systems for PrepegsEpotec® Prepreg Resin systems are solvent free systems which provide long shelf life at room temperature. These systems are suitable for wide variety of reinforcements and components of different dimensions

Hand-Lay up Resin Systems
Epotec® Resin and Curing Agent System for Hand - Lay Up Resins are designed to provide optimum initial mix viscosity which enables good wetting and fibre impregnation with minimal dripping on vertical & inclined surfaces. The choice of system can be made depending on the application and curing conditions. Faster curing hardners are preferred for repair applications.
