Henkel (Düsseldorf, Germany) reported at JEC Europe 2013 that it has worked with machinery manufacturer KraussMaffei (Munich, Germany) to reduce the cure time of its Loctite MAX 2 polyurethane matrix resin to just one minute in a resin transfer molding (RTM) process. The resin system and process are targeted to automotive composites manufacturing. Henkel claims that due to its low viscosity, Loctite MAX 2 penetrates and impregnates fiber material more easily and less harshly than competitors’ solutions, enabling very short injection times. The Henkel/KraussMaffei RTM process includes fabric preforming, one-minute injection and cure, postcure and finished part surface preparation. Henkel said at the show that it is seeking applications and partners to further test and assess the process.
