To fabricate its IMS 2001 World championship winning Sinergia 40 racing yachts, Spain's Sinergia Composites relies on a fast-setting, toughened methacrylate adhesive to bond thermoplastic, composite, and metal substrates. The methacrylate, called Araldite 2022, comes from Vantico Inc., Los Angeles. It replaces a conventional polyester-based system typically used for boat building. According to Jose Coello, manager of Sinergia Composites, the polyester-based material could not withstand the intensive strain put on the bonded joints during racing.
Araldite 2022 has a lap sheer strength of 3,600 psi, peel strength of 23 pli, and a service temperature of up to 212°F. It also has good resistance to the harsh environmental conditions encountered at sea. Its 1:1 mix ratio by volume permits packaging in 50 and 400-ml dual-barrel cartridges. This, says the company, provides precise resin/hardener mixing and clean, waste-free dispensing. The adhesive requires minimal surface preparation to reduce fabricating time and is gap filling up to 4-mm thick.
