Definition - What does Solventless Coating mean?
A solventless coating is a type of fluid that is applied to a substrate's surface to prevent corrosion. A solventless coating has an impermeable preventative layer with low or no moisture content, which helps reduce an electrolytic attack on the metal's surface.
Corrosionpedia explains Solventless Coating
Solventless coatings are widely used in the pharmaceutical, food and mineral processing industries to reduce or eliminate reactivity between processing pipes or vessels and the final product. These coatings facilitate the following desirable properties:
- Superior aesthetic product quality and a timed release of key active ingredients in pharmaceuticals
- Reduced interactivity with solvents
- Reduced processing time and cost
- Environmentally sustainable processes that do not require heat input
- Low emission rates of volatile organic compounds (VOCs) and a high solid content
