One example is AOC, a Collierville, Tenn.-based global supplier of resins, gel coats, colorants, additives and synergistic systems for composites and cast polymers. It recently developed its Vicast A830 polyester casting resins for cultured marble manufacturers that want to lower material costs by 10 percent or more. Users save money because the technology is designed to work when more filler and less resin is used to produce finished marble composite products such as vanity sinks, tubs, shower pans, fireplace surrounds and flat panels.
“It may seem unusual for a resin supplier to pioneer technology that lowers resin consumption per part,” said Fletcher Lindberg, AOC’s business manager of non-reinforced products, adding that Vicast resins reinforce AOC’s commitment to help customers become more profitable and competitive. AOC provides a material cost reduction calculator to clients who use the new resin technology.
Another resin supplier making advancements is Warwick, R.I.-based RBC Industries. Its research and development lab recently worked with B&G Shore Products to develop a special epoxy adhesive to create The Harpoon, a design-your-own-fishing-hook kit. B&G wanted to fabricate the kit so that fishing enthusiasts could design their own customized stem hook rigging system in the field, so the adhesive joining the harpoon barb and hook had to cure very quickly. The consistency of the adhesive needed to be formulated so that the material could be easily applied without drips or sags. RBC’s successful two-component adhesive cures in eight minutes and forms a tenacious bond.
“The overriding factor in resin development is the specific needs of clients—that’s the key focus,” Lindberg says.
