Resins help eliminate paint for
furniture makers
A family of widely used conductive resins grades originally developed for European automotive manufacturers, are becoming equally successful in a new industry - office furniture.
GE's Noryl GTX resins, a family of widely used conductive grades originally developed for European automotive manufacturers, are becoming equally successful in a new industry - office furniture Specifically, Noryl GTX conductive resin is being used in powder-coated moulded plastics furniture, providing a host of design, aesthetic, environmental, and cost benefits compared to moulded-in colour, wet-painted parts, and even powder-coated metal

Thermoformable composite replaces steel in bonnet
A major UK automotive molder will be replacing the steel with a low-pressure thermoformable composite in the bonnet/hood of a high-powered sports vehicle.
Among these are greater design freedom that helps enable part consolidation, lower weight than metal, and the elimination of paint solvents that can negatively impact the environment.
The two key properties required for successful powder coating are conductivity and high heat performance, both of which are features of Noryl GTX resins - a blend of polyamide (PA) reinforced with modified polyphenylene ether (MPPE) polymer technology.
In the powder coating process, a fine, dry electrically charged powder is sprayed on the plastics part surface, which holds an opposite charge.

Team to advance polycarbonate automotive glazing
The cooperation of a leading automotive equipment supplier and the leading international polycarbonate glazing specialist heralds a new era in automotive design.
The attraction between the charged powder and part results in an even coating.
The coated part is then cured at a high temperature to create a durable finish.
* Finishing process that supports the environment - one of the most valuable benefits of GE's Noryl GTX resin for powder-coating applications is that it helps eliminate conventional wet-paint systems, which typically have a high solvent content.
The powder-coating paint system contains no solvents that can cause harmful volatile organic compounds (VOCs) to be released into the environment.
Noryl GTX resin may also reduce costs by eliminating secondary operations, such as applying a conductive primer to non-conductive plastics parts.
Furthermore, companies can potentially avoid capital costs for VOC recovery systems which may be required with solvent-based paint systems.
* Greater design freedom - another important advantage from using powder-coated plastics for furniture is design flexibility that far surpasses that of metal.
Used for furniture components, GE's Noryl GTX resins can be moulded into unique shapes that are highly conductive, providing exceptional coating adherence.
The powder coating process also yields exceptional colour depth, quality, and richness for a competitive differentiation.
Finally, plastics parts can now be powder-coated in the same process and with the same colour as metal parts for improved aesthetics avoiding the colour mismatch often seen between powder-coated metal and injection-moulded plastics.
"Our customers are achieving great results by using Noryl GTX resins to elevate utilitarian office furniture into beautiful designs," said Kristi Dolan, product market leader, Noryl resin, Europe, GE Advanced Materials.
"This versatile resin helps designers to achieve the same finish as on metal parts, but with the design freedom that plastics has to offer." * High Performance - GE's Noryl GTX resins offer a number of outstanding performance characteristics, including high-temperature resistance that enables it to withstand the curing process, which requires temperatures from 180 deg C-200 deg C.
They also exhibit excellent chemical and impact resistance.
In addition to office furniture such as chairs and cabinets, applications for Noryl GTX conductive resins include lighting fixtures, appliances, and parts for vehicles including motorcycles and scooters.
Their use continues to expand in the global automotive industry, as well.
