Mould Release & Surface Prep

Guidance on mould release agent selection, mould preparation and surface chemistry for composite tooling. Articles cover the differences between conventional solvent-based waxes, semi-permanent release systems and water-based release agents — including when each is appropriate, how to apply them correctly and how to diagnose and resolve release failure. Mould preparation topics include sealing, priming and cleaning procedures for new and in-service composite tooling. Content addresses polyester, vinyl ester and epoxy resin systems across the marine, construction, wind energy, aerospace and leisure sectors. Articles are written for process engineers, tooling managers and production supervisors responsible for mould release performance at UK and Irish composite facilities.
