Scott Bader at China Composites Expo: to Display Urethane Acrylate-based Acrylic Resins and more

Published on 2013-09-05. Author : SpecialChem

Scott Bader Asia Pacific is exhibiting at the 19th China Composites Expo 2013, which runs from 11-13 September at the China International Exhibition Center, Beijing. This year on the Scott Bader stand (BK41) several new specialty resin, tooling and adhesive products will be shown for the first time in China.

The extended Scott Bader product range has a number of new products with particular application and production benefits for mass transport and vehicle component manufacturers. New products being shown includes: Crystic® Gelcoat 15PA, a new vinyl ester (VE) spray tooling gelcoat; Crestapol® 1250 LVE a new longer shelf life 'Export' grade; plus a number of ATC products, which have now been added to Scott Bader Asia Pacific's range following the acquisition of ATC Formulated Polymers Inc. by Scott Bader back in February of this year.

Crystic Gelcoat 15PA is a new vinyl ester (VE) spray tooling gelcoat which Scott Bader first launched back in March at JEC Europe 2013. This high performance tooling gelcoat offers superior gloss retention and surface finish. Crystic Gelcoat 15PA spray tooling gelcoat is a key addition to the Scott Bader Crystic 'matched tooling' system, which offers mould makers a brush tooling gelcoat if preferred, along with a VE skincoat and a choice of standard or rapid tooling back up resins.

Additionally for tooling moulds, plug and pattern production, two POLY-FAIR® modified polyester tooling compounds from ATC Scott Bader are also being showcased at China Composites; an extrudable and sprayable version. Poly-Fair T28 is the extrudable tooling compound, designed for milling of small and large plugs or direct limited production moulds using Computer Numerical Control (CNC) multiple axis machines. Poly-Fair T27 is the sprayable version, which is also fully CNC machinable. It is designed for milling patterns and large plugs with dimensions of 10-25 meters (30-75ft) or direct limited production moulds. It can be sprayed with several passes up to a thickness of approximately 25mm (1"). Both Poly-Fair grades offer the benefits of low shrink, high toughness and dust free cutting to produce a highly accurate profile of the finished part.

Other ATC products being promoted on the Scott Bader Asia Pacific stand are the low-density polyester based POLY-BOND® displacement molding compounds (DMC), which are designed to fill the space within fiber reinforcement layers and cores when compression moulded. Sandwich construction parts can be very cost effectively manufactured in a single cycle using a low pressure, closed mould compression-type processes. Two DMC grades are offered, standard Poly-Bond B55 and B55LV, a low viscosity version.

As well as the new longer shelf life Crestapol 1250 LVE export grade, the full range of Crestapol urethane acrylate based acrylic resins will also be promoted during the expo. According to Scott Bader, Crestapol acrylic resins offer a real alternative to phenolics and epoxies for applications requiring exceptional fire, smoke and toxicity retardant (FST) properties. All Crestapol grades available can be heavily ATH filled, offering designers a combination of superior mechanical strength, toughness, outstanding FST and high temperature performance. Crestapol resins are suitable for many building, passenger rail and other land transportation applications. Crestapol 1250LVE will be of particular interest in China as it can be reinforced with carbon fibers as well as glass fibers; high performance parts can be moulded at room temperature by vacuum infusion or resin transfer moulding (RTM), with a good surface finish and minimal print through.

The Scott Bader stand will also feature an extended adhesives range, with the addition of the polyester based Poly-Bond structural adhesives for fiberglass bonding from ATC, alongside Scott Bader's Crestabond® range of 10:1 and 1:1 ratio primer-less methacrylate structural adhesives designed for rapidly bonding a wide variety of composites, metals and plastics commonly used in industrial applications. Crestabond adhesives require minimal surface preparation, have excellent fatigue and impact resistance, and can be applied using manual or pneumatic guns with automated dispensing machines. The combination of a fast cure with an ability to bond such a wide variety of different substrates has provided many manufacturers with significant shop floor advantages, cost savings and productivity benefits during assembly when they switch to Crestabond. These advantages have been proven in practice by a number of truck, bus and vehicle manufacturers around the world who have switched to using Crestabond.
