HexPly® M19.1/M19.6 80 – 160 °C curing epoxy matrix Product Datasheet Description HexPly® M19.1/M19.6 is a formulated epoxy resin which is suitable for low pressure moulding processes. It is very versatile and allows a range of processing temperatures from 80 °C up to 160 °C. HexPly® M19.1/M19.6 can be used for very large industrial components subjected to severe environmental conditions. The HexPly® M19 range of prepregs are designed for Industrial applications where a greater control of adiabatic heat build up (exotherm) is required in order to reduce dwell phases during the cure cycle. HexPly® M19 overcomes this by providing a reduced exotherm matrix system which allows for higher temperature dwell phases to be used for a shorter length of time whilst at the same time limiting the maximum temperature observed during the exotherm. HexPly® M19.1/M19.6 has high fatigue resistance and gives a good surface finish. HexPly® M19.1/M19.6 exhibits a very long out life at room temperature. Several variations are available including: HexPly® M19.6 for medium tack HexPly® M19.1 for high tack Benefits and Features Very high flow matrix Excellent tack life Well adapted to low pressure processing Suitable for a range of pressures (0,5 to 5 bar) Versatile cure cycle 80 – 160 °C Good flexibility and handling of prepreg Suitable for thick laminates Good surface finish Low resin density Excellent fatigue resistance Translucent resin after curing Reduced exotherm
