PV Rail Bonding Adhesives 

Enhance installation efficiency, cost savings and performance.

Rail bonding adhesives eliminate the need for mechanical fasteners

Durable, structural strength for cost-effective mounting of solar panels

Installers, integrators and module manufacturers can depend on the proven performance of Dow Corning® brand PV solar sealants and adhesives for cost-effective, durable mounting of solar panels. Rail bonding solutions from Dow Corning use a silicone adhesive to structurally attach glass, metal or other PV module material to the supporting structure (rail or pad).

Specifically designed and tested for structural application in the PV industry, silicone rail bonding technology from Dow Corning can:
•Enhance the mounting process, enabling a lower installed cost per MWp
• Enable on-site ease of installation compared to mechanical mounting hardware, such as brackets, clips and screws
• Reduce material and installation costs
• Reduce module damage from stress points caused by the mounting hardware

Silicone rail bond adhesives outperform typical PV tapes

In recent testing of Dow Corning® brand silicone rail bonding solutions against two well-known global brands of photovoltaic (PV) tape, Dow Corning® brand silicone products outperformed tapes in cohesive failure and shear strength tests.
