The epoxy system is a polymer formed by the reaction between epoxy resin and polyamine hardener. In the field of composite materials, epoxy resin systems are widely regarded as superior to all other systems in terms of both mechanical strength and the degree of surface finish they provide. Since epoxy resins do not contain any solvents, they are not very aggressive towards the materials to which they are applied. Also worth mentioning is their very high adhesive strength, mechanical resistance and resistance to the hydrolysis reaction, capable of protecting a hull from the normal osmosis process. Making the same mould in epoxy will result in perfect release, practically zero elongation, even when moulded at high temperatures, and a very long service life.
A selection of room temperature epoxy layering systems with low viscosity and a wide application spectrum. Excellent for laminating glass fibre, carbon fibre, aramid and polyethylene reinforced articles. For use at room temperature or moderate to high temperatures in hand lay-up, injection or vacuum bag moulding and surface infusion. Can also be used for press and autoclave moulding.
In-film resins allow the production of impregnated fibre-reinforced laminates through a simple increase in temperature and pressure on the dry fabric pre-positioned inside the mould; the best alternative to pre-impregnated fabrics, which are widely used materials but at the same time complex to handle. Thanks to this innovative product family, a new production process commonly referred to as RFI – resin film infusion – has been gaining ground for a few years now; during handling, production and polymerisation, there is no release of hazardous vapours, and the film is very easy to handle.
