Superior Adhesion with Interplastic's New Line of Vinyl Ester Resins

Published on 2009-07-29. Author : SpecialChem

St. Paul, MN -- Interplastic Corporation announced its new line of vinyl ester resins for acrylic adhesion applications. The CORVE8132LH series are low HAP (hazardous air pollutant) vinyl ester resins designed for superior adhesion to acrylic in a wide range of conditions and applications. It is a high strength MACT compliant product for open mold applications such as tub/shower, whirlpool spa and hot tubs.

For manufacturers the temperature of the mold, resin and air during an application all play an important part in the adhesion of resin to the acrylic substrate. Interplastics CORVE8132LH series resins were specially designed for composite manufacturers to use in open molding applications as low as 13°C (55°F). Selection of the proper resin is crucial to getting the proper adhesion to provide strength and hardness to the finished product. A typical application would be using this new resin as a skin coat behind a thermoformed acrylic sheet to promote adhesion between the acrylic and the structural laminate. As the industry converts to vinyl ester resins with lower HAP levels, costly bonding failures due to cooler shop conditions can be reduced using CORVE8132LH series resins.

Interplastic Corporation is a specialty chemical company with its headquarters in St. Paul, Minnesota. Its Thermoset Resins Division focuses on the production and distribution of unsaturated polyester, vinyl ester resins, gel coats, and colorants for the composites and cast polymer industries. The Molding Products Division is a leader in the production of sheet molding compounds and other thermoset molding materials. Interplastics North American Composites division is a national, full-service supplier to these same industries.
