Interplastic Makes a Splash with Sun Fiberglass

Sun Fiberglass Pools in Brooksville, Florida, have used Interplastic’s products since the company produced its first pool in 1995.

“I became familiar with Interplastic while working for a previous manufacturer, and regarded them as a high-quality supplier,” says Curt Prystupa, founder of Sun Fiberglass Pools. “I consulted with them and enlisted their technical expertise to determine the best way to integrate their products into the manufacture of our one-piece fiberglass swimming pools.”

Sun Fiberglass Pools feature CoRezyn 8100 series vinyl ester resin at the core of their pool skins. This epoxy vinyl ester product is designed to strengthen the surface, giving the pool body flexibility and resistance to osmotic blistering, fatigue, moisture, and chemicals. With low hazardous air pollutants (HAP) ratings, they meet the latest EPA standards and volatile organic compound (VOC) requirements of Southern California’s South Coast Air Quality Management District’s Rule 1162 for High Strength Resin.

Sun Fiberglass Pools also use two other Interplastic products — Integrity high-performance gel coat and the primary laminating resin. The first product applied to the pool mould to begin the fabrication process is gel coat, which provides a smooth interior finish on the pool. The gel coat has a gloss finish with rich colours, and provides bacteria, water and crack resistance to prevent penetration to the other layers.

After the gel coat is applied to the mold to form the pool skin, layers of fabric and CoRezyn (COR61-AA-531) laminating resin is applied. COR61-AA-531 is designed to minimize shrinkage and exothermic reaction during the curing process, resulting in a superior surface quality. Reinforcing materials are then applied to strengthen the side walls. After the layers are applied to the pool mold, the new pool skin is removed from the mold, then cured, trimmed and transported to the customer.

“Vinyl ester resin was an innovation and a driving force in our industry. It eliminated problems in pool manufacture, including bleedthrough on the pool surface and body inflexibility,” says Prystupa. “Even if another company offered products similar to those from Interplastic, its technical experience and customer service are superior. We have easy access to and support from Interplastic’s technical staff.”

Prystupa’s work with Interplastic’s technical support extends to product development. “In the last year, we worked closely with them to develop a special-effects gel coat — a variation of the product we have used for years,” he says. “A blue polyester flake is added to the gel coat to provide an aggregate look and give customers more choices.”

CoRezyn vinyl ester resin was the focus of the company’s 15-year immersion study, which analyzed the effects of water immersion on laminate panels constructed with 100 percent CoRezyn vinyl ester resin or a vinyl concluded that the vinyl ester resin created a barrier impervious to water, preventing osmotic blistering. The panels also retained their original physical properties, including flexural strength and modulus and Izod impact strength.

“I grew up in the pool business. My family sold above-ground pool kits in New England,” says Prystupa. “The industry has always lacked research and development. Today, Interplastic addresses the needs of the industry by developing products to meet them.”
