ClearSignal® for Long Term Biofouling Protection

ClearSignal® for Long Term Biofouling Protection

High levels of adhesion and greater hardness then other foul release coatings

ClearSignal® is a silicone hybrid foul release system developed to meet the need for a foul release coating that with the lifespan of the subsea equipment to which it is applied.
The design goal for ClearSignal® is a 30-year lifespan. The product is now approximately 10-years old and has achieved very high levels of success. Several case studies of long-term deployments where periodic inspections show excellent biofouling resistance and no deterioration of the coating system after long term immersion.
The longest deployments to date are of the order of 8-years. The ClearSignal® developer, Severn Marine Technologies conducts a continuously expanding systematic testing series of ClearSignal® coated test panels using of all of the various substrates that can be coated. The test plates are subjected to high levels of UV exposure in order to stress the coating and are then immersed in seawater. The samples are periodically tested for adhesion to the substrate and overall coating condition with longest immersions for this ongoing testing now at 9-years.
The Severn Marine Technologies systematic series of testing described is very effective and has been shown to have a high correlation to the real-world use of ClearSignal®. Representative user deployments provide strong indications that ClearSignal® is suitable as a biofouling control system that has a 30-year lifespan. Customers selecting ClearSignal® for biofouling protection of subsea structures, devices and instruments can have confidence that ClearSignal® will be effective for the life of the deployment.
