Evonik meets SpeedFoilerTM
Evonik Industries manufactures a range of products that can be found in almost all components of fiber-reinforced composites. We supply core materials for sandwich construction, thermoplastic and thermosetting resin matrices, as well as the essential components for matrices such as crosslinkers, catalysts, impact strength modifiers or processing and process additives. Some of these products are used in sizings for glass or carbon fibers, and in adhesives for joining fiber-reinforced composites.
The combination of high quality products and process know how makes the new SpeedFoilerTM to a state-of-the-art catamaran. Most notably are the products VESTAMIN®, VESTANAT® and ROHACELL®.
Curing agents for epoxy resins systems, chain extender for PUR systems and raw material for polyamides
Aliphatic diamines from the VESTAMIN® range are industry-standard crosslinkers for high-performance epoxy systems. Typical applications include industrial floorings, marine and anticorrosive paints. Also, high-performance composites are a major field of application. All major processing field like Resin-Transfer-Molding (RTM), wet-pressing and also pultrusion are covered. Epoxy coatings are used as primers and intermediate layers because they offer outstanding mechanical and chemical resistance. They are extremely durable and have excellent adhesion to a variety of substrates.
Aliphatic and cycloaliphatic diisocyanate monomers for light stable PUR resins, elastomers and composites / Cycloaliphatic polyisocyanates for extremely durable coatings
VESTANAT® non-yellowing crosslinkers for 2K or 1K thermosetting PUR coatings improve performance in various applications and systems of all kind. They enable highly chemical resistant 2K and 1K systems and improve flexibility of PCM applications. Benefits are a high Tg and fast drying behavior to name but a few. VESTANAT® products can be used in solvent-borne, water-borne and solvent-free (e.g. powder coatings) systems. IPDI is characterized by its excellent compatibility for any kind of coating resin and comes with a low prepolymer viscosity. H12MDI for PUD and TPU applications exhibits high chemical resistance and excellent mechanical properties. TMDI shows also a superior compatibility and moreover an excellent performance in flexibilzation of UV resins.
The VESTANAT® M range is a new family of urethane-alkoxysilane binders and crosslinkers that provide excellent scratch resistance, especially for automotive OEM and repair coatings as well as wood coatings. This new technology is a versatile basis for high-performance isocyanate-free (NISO) technology used in both ambient-temperature-curing as well as thermosetting systems.
VESTANAT® PP is a matrix system for PUR prepregs based on aliphatic diisocyanates. It enables a completely new way of processing and an opportunity for automation on an industrial scale. Evonik’s new polyurethane prepreg offers very good overall properties with very high ductility combined with superior surface properties. Preforms can be made without addtional binder and laminates can be pressed without infusion times, resulting in a shorter overall cycle time.
Foam cores for composite sandwich structures
For more than 40 years, Evonik’s ROHACELL® structural foam has been offering the aerospace and automotive industries, medical technology, and other markets boundless possibilities for lightweight construction of parts or products made from high-performance composites. In such applications ROHACELL®, which is based on polymethacrylimide (PMI), is used as a core between, for example, CFRP facings.
Surface modified silica nanoparticles
Evonik is the leading manufacturer of surface modified silica nanoparticles in epoxy resins. Using NANOPOX® the performance of fiber-reinforced composites parts can be improved significantly: modulus, strength and compressive strength as well as toughness are increased. The fatigue performance is improved significantly. And due to the small particle size of 20 nm viscosity is not increased. Furthermore even close meshed fabrics are penetrated by the particles. This makes NANOPOX® suitable for all manufacturing processes like prepregging, filament winding, infusion or RTM.
