The Dow Corning® brand silicone adhesives and sealants offer installers and integrators a cost-effective solution to mount solar modules while producing more durable rail bonding, lowering the installed cost per megawatt hour.

The silicone technology also provides ease of installation compared to processes that incorporate mounting hardware, such as brackets, clips and screws, while reducing materials and installation costs. In addition, these silicone sealants and adhesives can minimize theft and module damage.

Dow Corning® brand rail bonding solutions incorporate a silicone sealant or adhesive to structurally attach glass, metal or other PV module materials to the supporting structure (frame, rail or pad).

"Because rail bonding is a high-performance application, not all sealants are suitable," said Axel Giesecke, Dow Corning global marketing manager of PV module assembly and system installation. "Silicone sealants, such as those from Dow Corning, have been developed and tested specifically for structural bonding applications for the photovoltaic industry. Using structural silicone adhesives as an alternative to mounting hardware can help reduce costs and breakage."

The Dow Corning® brand structural sealants recommended for frame or rail bonding include Dow Corning® PV-8301 Fast Cure Sealant, Dow Corning® PV-8303 Ultra Fast Cure Sealant, and Dow Corning® PV-8030 Adhesive.

 Overall, Dow Corning rail bonding solutions provide proven performance as well as a more efficient way to install PV modules, including:

• Protection from moisture, environmental attack, thermal and mechanical shock, breakage and vibration
  
• UV stability
  
• Added durability and structural strength
  
• Adherence to glass and metal rails
  
• Combined with equipment solution, provides an easy-to-use total process
  
• Reduced cost of ownership
  
• Quick cure time – for ease of use
  
• Multiple application options
  
• Warranties available with proper application
