Superior Class A for Trucks
AOC's Atryl® resin has established the standard for Class A surface excellence for cars, light truck and medium- and heavy-duty trucks. Atryl technology incorporates a proprietary toughness that results in a dramatic decrease or elimination of “paint pop” defects on the surface of painted SMC parts.
With the revolutionary resin from AOC, truck OEMS are getting the best that sheet molding composite (SMC) has to offer. The material system’s lower weight, low tooling investment, parts integration, design freedom and corrosion resistance are combined with a high quality surface finish that has become an essential element of new truck marketing.
Leading the market for Atryl use in medium- and heavy-duty trucks is Meridian Automotive-produced hood-fender assemblies on Freightliner Century Class S/T and Columbia models and fenders on the Sterling Acterra. These were the first production parts to be molded of a Atryl formulation that can be compression-molded at lower pressure.
For large fleets as well as owner operators, appearance plays a decisive role in the purchase of a medium- or heavy-duty truck,” stated Mike Dettre, Business Manager - Closed Mold for AOC. “To satisfy the need for superior aesthetics and durability, more truck body engineers are discovering howAtryl resin has radically elevated the surface quality of SMC.”
Best Composites in Trucking
Truck parts for Atryl resin are compression molded of 28% fiberglass-reinforced SMC in the Salisbury, NC, plant of Meridian Automotive Systems. Bob Moore, Manufacturing Engineering, Manager, Heavy Truck, for the Salisbury, NC, plant, said Atryl offers distinct advantages. “Compared to other SMCresins, Atryl is more user friendly, molds better and holds dimensions better,” said Moore. “And with this resin, we can mold at 20 percent lower pressure which is easier on the presses.” The parts use an in-mold coating in conjunction with Atryl to achieve the ultimate in Class A finishes. After the hood and two fenders are molded, the components are adhesive-bonded together into hood-fender assemblies. The 95-inch wide by 72-inch long by 48-inch high (241- by 183- by 122-centimeter) assembly for the Columbia was the first Atryl application of this size.
