Two new release agents for FRP applications

The global leader in the development and production of highly effective release agents, purging compounds, and other ancillary moulding products, Chem-trend, has launched two new release agents for FRP applications - Chemlease 5127 and Chemlease 5128. The two silicone-free, solvent-based universal release agents combine proven technologies with ease of use.


Chemlease 5127 and Chemlease 5128 are silicone-free sacrificial release agents that offer a high level of quality at predictable cost in the production of components from fibre-reinforced plastics. Chemlease 5127 is particularly suitable for the manufacture of components with epoxy resins, while Chemlease 5128 is the product of choice for moulding polyester components and manufacturing parts with and without gelcoats.


Both products are universal liquid waxes: Chemlease 5127 is softer and Chemlease 5128 is harder. They can each be used in a variety of ways in the field of fibre-reinforced plastic and are particularly suitable for small-lot production. Possible applications include in the manufacture of components for products such as boats, pools, bathtubs, and shower trays. The field of architecture is another potential application area, where the two products can be used in the production of large-scale parts such as facade panels.


When manufacturing parts with gelcoats, Chemlease 5127 and Chemlease 5128 enhance wet adhesion. This prevents pre-release and the formation of fish eyes. Chemlease 5128 is especially suitable for achieving a high gloss mould finish. The two products are available now throughout Europe.
