Describes a polyamide resin matrix generation

Through the development of its new polyurethane matrix resin Loctite (Loctite) MAX 3, Henkel (Henkel) composite components to the automotive industry fully automated mass production has taken an important step. Global market leader in adhesives, sealants and surface treatment technologies by hand in Germany Henkel Krauss-Maffei (KraussMaffei), has been developed based on the component manufacturing process of glass fiber or carbon fiber , the use of high-pressure RTM (HP- RTM) technology to create high-quality automotive body exterior surface .

Roof section Roding Roadster R1 models is the use of this light- weight, high -strength carbon fiber material model , the innovative production processes will be unveiled on held October 16 to 23 in Dusseldorf, Germany, plastics and rubber industries the world's most important trade fairs (K exhibition ) .

Lightweight construction techniques become increasingly important in the automotive industry, because these technologies help to reduce vehicle weight of the car. In response to the strict exhaust emissions requirements faced and as a way to reduce fuel consumption and lower CO2 emissions , lightweight construction technology is increasingly becoming a necessity. Based carbon fiber or glass fiber composite materials will combine light weight and high strength , provides a safe and superior performance is closely related crash .

Until now , the use of lightweight components are also subject to certain restrictions . These components are subject to the automotive industry and the level of automation and cycle requirements related restrictions. Especially after the necessary follow-up spraying surface treatment process is too time-consuming and must be done manually , so rarely used in composite materials for external components production vehicles. Provide for the plastics manufacturing and processing machinery and equipment leading manufacturer Krauss-Maffei , joint matrix resin Henkel experts with global independent developer active in polyurethane systems Rühl Puromer GmbH, has successfully rely on a fully automated process to produce a surface quality suitable for direct painting the composite components .

Three -component polyurethane matrix resin system developed this result benefited from Henkel Loctite MAX 3 - which includes not only the resin and hardener , also includes a high-performance internal self- shedding polyurethane varnish with Rühl Puromer GmbH matches release agent. Therefore , Henkel - along with Germany Dieffenbacher (Dieffenbacher), United States Zoltek (Zoltek), Chomarat, Rühl Puromer, Alpex, Mühlmeier and Roding Automotive - Krauss-Maffei has become a professional network of partners in a member , committed to building a mature and reliable production chain, including fiber and matrix materials and finished parts .

Enhance the heat resistance immediately after ejection

Compared to RTM ( resin transfer molding ) process often used in epoxy resins , polyurethane-based resin technology developed by Henkel substantially increase the cure speed. Due to the low viscosity of the polyurethane base resin of the resin into the fiber material more easily , splitting of less generated , thus shortening the injection time, thus shortening the production cycle time.

Loctite MAX superior toughness 3 is also conducive for optimum component structures. Henkel also improves the heat resistance of polyurethane resin , so that the Loctite MAX 3 upgrade on this particular property to be comparable epoxy height. High temperature performance fiber-reinforced composite materials can mean more rapidly stripping. Internal mold release agent to ensure that the component from the mold easily , so that the surface quality of the synthesized material is excellent enough to achieve coating and the adhesive immediately . This accelerates the production process , and to ensure that the production of the externally visible components with excellent surface quality .

Flexible integration within an integrated conceptual framework

Especially for the automotive industry is concerned , can be integrated into an overall plan for the complete set of application-ready technology is essential . Therefore , Henkel offers adhesives self -made , designed to ensure that the joint process within the conceptual framework of advanced composite materials to achieve reliable the different components of the material. If these binders to give full play to their potential role in a variety of different elements need to ensure perfect coordination.

Henkel (. Henkel AG & Co KGaA) Frank Deutschländer , global automotive marketing manager , said: " Loctite MAX 3 now so that we have such a matrix resin system, which can further enhance the use of composite materials manufacturing automotive components brought feasibility and attractiveness through close cooperation with Krauss-Maffei , we have to optimize the performance of the resin , so the paint coatings and adhesives can be applied to the synthesis of composite material surface , without any pretreatment. " Henkel adhesive product portfolio provides a complete system solution , ensuring the production of synthetic materials with integrated automotive components.

Henkel experts will attend the October 16 to 23 organized by the "K 2013" exhibition, and Krauss-Maffei booth (B27/C24/C27/D24 booth ) answering questions at the 15th exhibition , against the company 's composite material produce product solutions provide insights and information.
