MEKP Catalyst for polyester resin topcoat & gelcoat systems. MEKP Catalyst is typically used as a polyester resin catalyst, fibreglass catalyst or vinylester resin systems at a ratio of between 1 and 3%, according to the pot-life and cure speed required and the ambient temperature. Always follow the guidelines that accompany your specific resin system. We of course have tested this hardener on the polyester resin systems we sell, It will work with other polyester systems we advise to do a sample test before undertaking a larger project. I would expect it to work with other polyester resins and topcoats that use the similar liquid MEKP hardener . IMPORTANT - We cannot guarantee this hardener will work with resins purchased elsewhere so it is critical to do a test beforehand before undertaking a larger project. The hardener is not compatible with ISOPON resin products that use a RED paste type of Hardener. NOTE - All resins are not the same -the two more common resins are either POLYESTER or EPOXY . This MEKP catalyst WILL NOT work with Epoxy resin . If you are using this hardener with a 3rd party resin, it is essential to do a sample test first. Safety Information MEKP is a powerful oxidiser and corrosive. Please observe the health and safety data.
