ITW Solar has released the Insulcast RTVS 400 series of thermal potting for solar applications. 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 in the RTVS 400 series family has a unique combination of flexibility and thermal conductivity for any product application needs that you might have. As a result, these silicones help to minimize the problem of solder joint fatigue and stress on components on micro-inverters, power optimizers, and charge controllers.
The RTVS 400 series are low in viscosity which helps the silicone flow easier to cover the components that it protects. The products are also very easy to mix and apply because of their one to one ratio. Additionally, a primer is not required to achieve good adhesion which saves time in production. They also fully meet the flammability requirements of UL 94V-0. The RTVS 400 series is currently available and being manufactured.
