Christopher Associates Offers Complete Line of Sealing and Bonding Adhesives for the Solar Industry

The company carries Tonsan's complete line of sealants and potting compounds for solar module assembly.

November 2010 ― Christopher Associates now offers Tonsan's complete line of sealants and potting compounds for solar module assembly. Tonsan is recognized as a global leader in solar module manufacturing technology. Many of the largest manufacturers in the industry already are using the Tonsan's sealants and potting compounds.

As a key supplier of adhesives and sealants for photovoltaic applications, Tonsan has a staff of more than 100 materials scientists and engineers working in a state-of-the-art facility. The company's qualifications include ISO/TS 16949, ISO14001, ISO18001, UL, IEC 61215 and IEC 61730.

Tonsan's 1527 Silicone Sealant was developed specifically for photovoltaic applications, especially module assembly. 1527 exhibits excellent adhesion to back sheet materials including TPT, PVDF and PET. The material performs especially well in heat/humidity testing. The elastic and bonding properties make it ideal for PV module structures where mechanical load caused by wind, snow, hail and rain can cause localized stress. 1527 is a low odor sealant that meets the Ultraviolet Light Exposure Test as required by UL 746C Sections 25 & 57.

Tonsan's silicone potting material is used to pot junction boxes to provide reliable sealing for diodes and connectors. Tonsan 1521 is a two-part, room temperature cure silicone system that provides excellent adhesion to PPO, TPT, brass and tin-plated leads. Tonsan 1521 features excellent aging and heat resistance in tough weather conditions and is ideal for use in automatic dispensing systems.
