Sherwin-Williams’ New Zinc Clad DOT - Inorganic Zinc-Rich Coating for Steel Bridges
Unique HAPS-free formulation is listed on NEPCOAT Qualified Product List A
CLEVELAND (September X, 2011)Steel fabricators increasingly need primers that meet EPA content restrictions on hazardous air pollutants (HAPS) while also offering protection on structural steel bridges, where coatings are subject to extreme corrosion due to weather and road salts. Sherwin-Williams today introduced Zinc Clad DOT, an inorganic zinc rich primer that is highly resistant to corrosion, high heat, humidity and salt fog, and is HAPS-free as supplied. This new fast drying primer has a smooth finish that requires less labor and sanding between coats than other zinc-rich coatings.
Sherwin-Williams is at the forefront of coating technologies that are safer for the environment and for applicators to use, and offer durable performance in harsh conditions, said Narsi Bodapati, Vice President of Marketing for Sherwin-Williams Protective & Marine Coatings. Zinc Clad DOT saves fabricators time and money by eliminating HAPS and minimizing the sanding required while providing a hard-working, reliable coating for bridge and highway use.
For use over prepared steel, Zinc Clad DOT can be applied in the shop or field. In addition, the new coating forms an inorganic barrier to moisture and solvents and meets Class B requirements for slip and creep resistance (0.65).
Zinc Clad DOT can be used as a one-coat maintenance coating or a permanent primer for severe corrosive environments and is a qualified product per Northeast Protective Coating Committee (NEPCOAT) requirements for new and existing steel bridges. It is also ideal for application at low temperatures or service at high temperatures and/or humidity.
