What is RTV?
RTV is a type of silicone adhesive used to bond and seals various components of the solar panel, including the junction box and the frame to the laminated cells.
RTV stands for Room Temperature Vulcanizing. It refers to a type of silicone adhesive that cures at room temperature without additional heat or pressure. RTV silicone adhesives are widely used in various industries, including photovoltaic (PV) solar panel manufacturing.
RTV is the adhesive/sealant of choice because it sets at room temperature, which makes it more convenient and cost-effective to use than other adhesives. It is also highly resistant to moisture and other environmental contaminants, which helps ensure the solar panel's long-term reliability and performance.
Its durable bonding can withstand various environmental stresses, including temperature changes, humidity, and UV exposure.
