Scott Bader (Wollaston, Northamptonshire, U.K.) is launching Crestabond M1-04, adding a “rapid bond” grade to the range of primerless methacrylate structural adhesives, with a fixture time of only 8 to 10 minutes. Crestabond M1-04 offers assemblers a reduction of more than 40 percent in the maximum fixture time when compared to the existing Crestabond M1-05 grade, with no loss of bonding performance properties. Crestabond M1-04 has been developed to increase production efficiencies for high-volume parts assembly. With no requirement for a substrate primer and a working time of only 3 to 4 minutes, assembled parts bonded with Crestabond M1-04 can be moved on to the next stage of production in as little as 8 minutes. According to Scott Bader test data, Crestabond M1-04 will effectively bond composites, plastics, ABS, aluminum, stainless steel and many other substrates commonly used in industrial applications. This new Crestabond grade is expected to be of particular interest to automotive OEMs and Tier 1 and Tier 2 suppliers due to its high elongation and toughness, its productivity benefits and its reliable long-term adhesion performance.
Also featured will be the Scott Bader-ATC range of POLY-FAIR modified polyester tooling compounds, now available in Europe for pattern and moldmaking. (POLY-FAIR was the trademark of ATC Formulated Polymers Inc., prior to the acquisition made by Scott Bader in 2013.) The extrusion and the spray grades of POLY-FAIR tooling compound will be showcased for the first time by Scott Bader in Europe, and a variety of tooling parts will be on the Scott Bader JEC stand in Paris; both versions are established in North America. POLY-FAIR T28 is the extrudable tooling compound, designed for milling of small and large plugs or direct limited production molds using Computer Numerical Control (CNC) multiple axis machines. POLY-FAIR T27 is the sprayable version, which is also fully CNC-machinable, designed for milling patterns and large plugs with dimensions of 10m to 25m (30 ft to 75 ft) or direct limited production molds. POLY-FAIR T27 can be sprayed with several passes up to a thickness of approximately 25 mm/1 inch.
Finally, Scott Bader will emphasize Crestapol high-performance urethane acrylate-based acrylic resins, which offer strong fire, smoke and toxicity (FST) performance. Products include Crestapol 1212 and Crestapol 1250LV, developed for closed molding of lightweight motorsports and transportation parts with woven fabrics made from glass, carbon and aramid fibres. A carbon fiber-reinforced Crestapol 1250LV front bumper from a Suzuki S1600 rally car will be exhibited on the stand.
