Solar thermal potting
ITW Solar has released the Insulcast RTVS 400 series of thermal potting for the solar industry. This new line of primerless, silicone potting is ideal for solar applications due to its combination of low durometer and high thermal conductivity. This leads to less stress on components during periods of thermal cycle and mechanical shock. The RTVS 400 series is comprised of the Insulcast RTVS 400, 440, and 480. Each product has a unique combination of flexibility and thermal conductivity with the ability to minimize solder joint fatigue, as well as the stress on components for micro-inverters, power optimizers, and charge controllers. The RTVS 400 series are also low in viscosity, which helps the silicone flow more easily to cover the components that it protects. The products are easy to mix and apply because of their one-to-one ratio, and they fully meet the flammability requirements of UL 94V-0.
