Coterill is a silicon based light absorber paint (absorbance ratio up to 98%) with high efficiency and reliability at high temperature(850°C). This allows a commercial Solar Receiver (used in Controlled Solar Power) to have high performances and reduce maintenance operation on site which leads to increase the availability and the electricity production of the power plant. Another advantage of this coating is its ability to be applied without curing which allows our customers to save money during the lifetime of the CSP plant and to avoid the risks of non-adequate curing to be performed on the top of the tower.

SiLight 850 is the next level in our development for these CSP coating applications. We have already developed and commercialized the predecessor of the SiLight 850 ( the Coterill 750 :
