Solar Junction Box Potting Compound

Solar junction box potting compound is a specialized material used to encapsulate and protect the electrical components within solar junction boxes. Designed to withstand harsh environmental conditions, this compound typically comprises a resin-based formulation that adheres strongly to various substrates, providing excellent moisture resistance and mechanical protection. Its primary function is to safeguard sensitive electronic elements from water ingress, dust, and mechanical shocks, thereby enhancing the longevity and reliability of solar power systems. Our solar junction box potting compound is a platinum-catalyzed silicone that cures through a sulfidation process. However, it is important to note that the presence of nitrogen, sulfur, phosphorus, and organic tin compounds can inhibit this curing reaction. Therefore, when applying the encapsulant on circuit boards, it is advisable to thoroughly clean any residual flux. Additionally, using solder with low lead content is recommended to ensure optimal results.
