Semiconductor Processing

The composite manufacturing specialists of RL Industries use Vipel corrosion-resistant resin technology and service from AOC to support the growing worldwide demand for personal computers.

RL Industries’ connection to the computer industry includes their expertise in special dual-laminate tank construction. For a recent expansion, a major U.S. semiconductor manufacturer needed seven dual-laminate tanks. Two tanks are for storing high purity sulfuric acid, which is used in a variety of semiconductor manufacturing processes. Heil Process
Equipment came up with a scrubber system that protects the environment if ammonia accidentally leaked from the refrigeration system into the production room.

For all vessels, the structural laminate that supports the liner is made of E-glass fibers in a resin matrix of Vipel F010 bisphenol A epoxy vinyl ester.

RL Industries’ craftsmen use spray-up to produce the tank shell and hand lay-up to produce the tank top and bottom and nozzle flanges. The composite manufacturing specialists of RL Industries use Vipel® corrosion-resistant resin technology and service from AOC to support the growing worldwide demand for personal computers. “In addition to providing the required physical properties, the Vipel resin processes well in both the spray-up and hand lay-up processes,” comments Brian Linnemann, Engineering Manager, RL Industries. “The resin has good wetting
characteristics for all the laminate reinforcements as well as a carbon veil that backs the thermoplastic to
meet requirements for high voltage spark testing.” The E-glass reinforcements for the application are 1.5 and 0.75-ounce (458 and 229 gram) chopped strand mat, woven roving and gun roving. Linnemann points out that there was more to the AOC resin purchase than material performance and processability. “AOC delivered on time through their
designated distribution channels,” he says. “AOC technical personnel were very responsive in providing base line resin chemistry and cure information to incorporate Vipel F010 into the fabrication processes.”
