Henkel has developed a polyurethane-based composite matrix resin that they say cures faster than the traditional epoxy resins.
According to Henkel, composites based on carbon fibre or glass fibre are gaining momentum in various application areas due to the opportunity for enormous weight savings over traditional part construction, with no loss in mechanical performance. They say that new manufacturing methods like resin transfer moulding enable economic processes that are suited for high volume automotive production.
For the resin transfer moulding process, Henkel has developed a new composite matrix resin based on polyurethane which enables improved economics and throughput in processing. Henkel say that compared to standard epoxy matrix resins, the new Loctite MAX2 cures significantly faster, and during injection, it also enables more efficient impregnation without stressing the fibres due to the lower viscosity of the resin.
The composite properties of Loctite MAX2 were specially developed to provide more flexibility as well as much higher impact resistance than traditional epoxy resins. Henkel is confident that this new generation of polyurethane matrix resins deliver significant benefits for fast and efficient manufacturing.
