Sherwin-Williams Protective & Marine Coatings Introduces Sher-Release Silicone Fouling Release Coating System

A solution that works with nature; causes marine organisms to be released from hull surfaces at slow speeds and light water pressure

CLEVELAND, Ohio (April 30, 2009) – Sherwin-Williams Protective and Marine Coatings announces new Sher-Release Silicone Fouling Release Coating System, an effective, nontoxic alternative to conventional antifouling coatings.  A U.S. Navy patented solution, Sher-Release combines durability, longevity, clean-ability and cost-effectiveness.

It is an ideal coating for hull applications to a wide range of ships, helping to prevent fouling of the underwater hull by barnacles, mussels and other marine organisms. The system’s foulant release technology combines an epoxy anti-corrosive system and a tough, protective silicone surface coat interlocked by a unique elastomeric formula.  The Sher-Release system’s “extra tough” surface provides steady long-term performance that is less prone to mechanical damages, not available in “softer” silicone systems.

Non-toxic Sher-Release contains no heavy metals or biocides.  It is effective at speeds as low as 10 knots and offers effective service for 60 months dry-dock interval.  Estimates show that Sher-Release can reduce fuel consumption by six to ten percent thereby reducing CO2 emission significantly 

“Sher-Release is a cost-effective method of providing superior biofouling protection for a wide variety of marine applications,” said Michael Bentkjaer, Sherwin-Williams Protective & Marine Coatings Market Director, Marine & Offshore.

Another environmental advantage of Sher-Release is its low level of Volatile Organic Compounds (VOCs).  It is easily applied by airless spray equipment and significantly reduces the maintenance and downtime of vessels.

Sherwin-Williams Protective & Marine Coatings delivers smarter asset protection to the Americas with a broad line of high-performance coatings, comprehensive technical service and the industry’s largest distribution system.  Relying on more than 140 years of experience in formulating protective coatings, Sherwin-Williams provides environmentally responsible and cost-effective coatings solutions for applications where extreme corrosion, abrasion and chemical attack are present.
