120 C curing epoxy matrix Product Data Description ® HexPly M10R is a formulated epoxy resin which is suitable for low pressure moulding processes. ® HexPly M10R is very versatile and allows a range of processing temperature from 85°C up to 150°C. HexPly M10R can be used for very large industrial components subjected to several environmental conditions and exhibits a very long shelf life at room temperature. ® HexPly M10R is used extensively for structural marine applications, recreational markets and a wide variety of industrial applications. ® HexPly M10R fulfils REACH compliance. Benefits and Features ■ Versatile cure cycles 85 - 150°C ■ Good tack life (up to 60 days) ■ High flow matrix ■ Good surface finish (using pressure) ■ Translucent resin after curing ■ Suitable for thick laminates ■ Available on large reinforcements range ■ Adapted to low pressure processing: suitable for a range of pressure 0.9 – 5 bar Resin Matrix Properties ■ Glass transition temperature* (TG onset) : 120°C * DMA Onset Tg after nominal cure cycle (60min at 120°C, at 5 bar pressure and -0.95 bar vacuum)

Product Data The nominal cure cycle for HexPly M10R is 60min at 120°C, heat up rate 3°C/min, 5 bar pressure and -0.95 bar vacuum. Time (minutes) Temperature (°C) HexPly M10R is a flexible curing system and can be cured at temperatures from 85 to 150°C, at pressure between 0.9 to 5 bar. Heat up rate can be also adapted (from 0.5 up to 10°C/min) depending the part design. Cure Temperature Time Curing Conditions What is the best cure cycle for vacuum process components? To ensure a minimum void content in the component, it is recommended to incorporate an intermediate dwell and a controlled heat...
