Jotun Paints Inc. (Houston, Texas, USA) recently introduced its Jotacote Universal S120 with groundbreaking COVALLOX technology. The solvent-free epoxy can protect structural steel and equipment in refineries, power plants, and other industries from corrosion for 20 to 30 years.
The technology utilizes Covalent chemical bonding between the paint and the substrate, which the company says is 10 times stronger than the typical hydrogen bond used in previous epoxy chemistries. This formulation uses bonds that chemically anchor the epoxy to the steel while preventing water from replacing the Covalent anchors.
By contrast, the original hydrogen bonds that have long been used in epoxies are quickly breached and replaced by water and other contaminates. In the field, Jotun has found no rust creepage or delamination after the coating is damaged.
The low-odor product, which can be applied by air, roller, or brush methods, has almost no volatile organic compound (VOC) emissions, and it also does not have hazardous air pollutants (HAPs) or crystalline silica.
