Nippon Paint developed a paint with less environmental load for outdoor iron structures. The company used water in place of organic solvents like thinner and succeeded in reducing the emissions of volatile organic compounds by 90%. The new paint is heavy-duty coating for such outdoor iron structures as bridge, plant, and tank. The newly developed technology prills epoxy resin and makes it easily dissolved in water, and dilutes it with water after reacting it with a substance like a surface-active agent.
The new paint is suitable for paint application in residential streets and crowded areas because it does not contain organic solvent. It reduces emissions of volatile organic compounds that cause air contamination and petrochemical smog considerably. It halves the term of works to two days. In addition, it is excluded from the list of dangerous substances specified by the Fire Defense Law, and it is not subject to the limit on the stockable quantity specified by the Fire Defense Law. The new paint is 30% higher in price than the conventional products.
The new heavy duty coating for outdoor iron structure like bridge developed by Nippon Paint scarcely emits volatile organic compounds that cause air contamination and petrochemical smog.
