Increase Solar Module Reliability and Protection

Applying potting agent to junction box

PV junction box potting agents 

Look to  Dow Corning® brand potting agents for a unique combination of reliable performance and durability for photovoltaic junction box applications.

Potting agents from Dow Corning improve the durability of PV modules even under the demanding outdoor exposures typical of photovoltaic applications. Pottants provide long-lasting protection to withstand the elements. Dow Corning pottants provide:
•Fire resistance
• Excellent electrical insulation of components
• Stability and flexibility over a wide temperature range
A range of globally available product options enhances manufacturing options:
•Room-temperature or heat-cure mechanisms
• Translucent or opaque product formulations
• Automated dispensing widely available

Effective thermal management solutions

Thermal management challenges can now be overcome even using smaller junction box designs. High thermally conductive index pottants from Dow Corning provide temperature management for effective diode protection. Less material for box construction and reduced pottant requirements mean lower total costs for you.
