49 CompositesWorld.com » THERMOPLASTIC RESINS & ADHESIVE SYSTEMS Light-cure adhesive for engineered plastics A new light-curing adhesive, Vitralit UV 4802, has been developed by Panacol (Steinbach, Germany) for the purpose of bonding high- temperature-resistant thermoplastics, such as polyetheretherketone (PEEK), with other, noncompatible materials. Vitralit UV 4802 is based on acrylate resin, which reportedly demonstrates excellent adhesion to many thermoplastics, including PEEK, polyethylene naphthalate (PEN) and thermoplastic polyurethane (TPU), which are typically difficult to bond using conventional adhesives. It also is said to adhere very well to ceramics and glass. Vitralit UV 4802 is highly resistant to heat: tests have shown that it remains soft and flexible even after exposure to temperatures of 150°C for seven days. Due to its high flexibility, the adhesive is reportedly well suited for bonding thin and bendable materials. The adhesive is pink in color and cures within seconds under either a UV or visible light source. Both gas discharge lamps and LEDs are suitable for curing. When cured, the adhesive fluoresces, which enables inspection of the bond line under black light. Vitralit UV 4802 is being launched in the UK by Techsil (Bidford-on-Avon, UK), Panacol's authorized distributor. panacol.com | techsil.co.uk » ADDITIVE MANUFACTURING EQUIPMENT & MATERIALS 3D printing filaments based on PEKK and PVDF Arkema Inc. (King of Prussia, PA, US) announced that new Kynar PVDF and Kepstan PEKK-based filaments are now available in 1.75-mm and 2.85-mm diameters from 3DXTech (Byron Center, MI, US) and are marketed under the Firewire trademark. Kynar PVDF, used for decades in demanding industrial applications, reportedly exhibits resistance to a wide range of aggressive chemi- cals. PVDF exhibits high thermal stability up to 150°C and extreme durability in direct sunlight exposure. Kepstan PEKK is said to be an extreme performance thermoplastic with a highly stable chemical backbone. Its semi-crystalline structure offers a combination of mechanical and thermal strength together with chemical and fire resistance. The Kepstan PEKK filaments, says the company, offer both ease of printability and the highest performance of any thermoplastic material currently available. arkema-americas.com EnableX™, from Norplex-Micarta, allows conƟnuous fiber pre-preg to be co-cured in a single step, mulƟ-material, molding system to produce near net shapes.
