Critical Marine Components Bonded Together With Araldite

10 July 2008

Marström Composite has been working with Huntsman Advanced Materials and their distributors in Sweden to build the largest catamaran in the world for the famous Polish yachtsman Roman Paszke.

The boat will be used to try and establish a new speed record around the world in the Jules Verne Trophy competition.

The catamaran is approximately 30m long and 15m wide with a deck area of 405m2. The boat is extremely light as it is made from epoxy prepregs and honeycomb, so weighs only 8 tons. To achieve the levels of component endurance and performance required in one of the world’s toughest yacht races, Marström Composite’s engineers used a range of Araldite® products to complete the boat.

Araldite 420, a two component epoxy adhesive which is particularly moisture resistant, has been used as a primer to get better adhesion with the laminating system, Araldite LY 5052/Aradur 5052, which has been used to bond the deck to the hull body. The high performance structural adhesives, Araldite 2014 and Araldite 2015 have been used to bond many other details on the boat and Araldite 204 epoxy has been used to fill up and reinforce the honeycomb cells.

“We use Araldite for such a wide range of applications because we have always had very good results from these products,” said Per Wärn, CEO of Marström Composites AB.

“All the materials we used have to meet very tough criteria. Not only do they have to obviously be waterproof– and salt water resistant too –but temperature is always an issue for us. Many black carbon fibre parts reach very high temperatures in the sun. Component and joint strength are also critical – the stress in joints often reaches maximum levels due to bending or shear strength.”

“Most of our marine components are used at the highest levels in competitive sports – the Olympics and World Championships,” said Per Wärn. “and we have been producing these using Araldite® products since 1985. They are able to meet these very demanding environments and now we have invested in new mixing and dispensing equipment, we have been able to improve processing times as well.”
