Why Release Agents?
Whether release agents are incorporated into the resin matrix or applied externally to the mould surface, correct selection can optimise not only cycle time, but also consistency of surface finish maintaining detail, minimising post mould operation prior to painting or bonding, even helping with fibre wet out. To work well a release agent must fit within the scope of the overall process and be cost effective. Application must be simple with clearly defined steps, drying times should be short and cure time if any must not delay the process. The product must not contain any ingredients which will affect the final product properties or post mould treatments. Finally release must be smooth and clean with no pre-release prior to cure. Qualification costs are high and CRC ensure their products and chemical pre-cursors are available long term, anticipating changes in legislation and using safe ingredients whenever possible.
