Fridolfing, Germany-headquartered Otto Chemie has released Novasil S 651, a silicone pottant for the filling and potting of PV junction boxes.

The proper function of junction boxes is essential for optimal PV installation performance, the company says. Critical points, such as electrical contacts inside junction boxes, need to be securely protected from moisture and dust during long-term exposure to weathering and wearing conditions.

Novasil S 651 is a two-component alcoxy-silicone pottant that combines low viscosity with high mechanical strength, according to Otto. Its composition ensures that all sensitive contacts can be embedded properly. Novasil S 651 also meets flame-classification V0 and offers strong performance under damp-heat conditions.

The product is expected to be available worldwide in the third quarter.
