Green Alternative For Conventional Solvent-Based DTM Coatings

Solvent-borne Direct-to-Metal (DTM) coatings are a type of industrial coating formulation designed to be applied directly onto metal surfaces without the need for a primer. These coatings contain solvents as a carrier medium, which facilitates the application process by providing the necessary viscosity for spraying or brushing. The solvents in these formulations evaporate during the drying process, leaving behind a protective and decorative coating on the metal substrate.

However, in the industrial coatings industry, the journey toward environmental sustainability has taken center stage. Conventional approaches often reliant on solvent-borne formulations for Direct-to-metal (DTM) coatings, have faced criticism due to their environmental and health implications. The release of volatile organic compounds (VOCs) during application contributes to air pollution, while the potential health hazards for workers and the community underscore the urgency of exploring more sustainable alternatives. 

Water-based Coatings For Industrial Applications

Water-based coatings for industrial applications have been available for many years. Despite significant advances in resin technology, their use remains limited in these markets compared to their adoption in the architectural coating sector. This can be attributed to perceptions of poorer performance and higher costs when compared to solvent-based solutions. The biggest driver for switching to water-based systems is the introduction of stricter VOC and other regulations around the globe, which can be met via the use of waterborne coatings.
