New advances in these products are allowing formulators to improve performance in areas traditionally dominated by solventborne coatings.Īdvances in the performance of waterborne coatings also contribute to their use in a wider range of applications.

In architectural applications, the lower odor levels of water-based paints are a big driver for their use as building occupants and industry operators become more concerned about solvent odors, according to Steven Reinstadtler, infrastructure marketing manager for Covestro LLC.
In China, the use of waterborne coatings has led to reduced waste-removal costs because the waste streams for waterborne are lower than those for dangerous solvent-containing wastes, adds David Vanaken, global technology director of Versatics at Hexion. For industrial applications, reducing explosion risk and lowering insurance fees is an important factor, according to Dan Weinmann, market development manager for Epoxy Specialties with Hexion. “Transitioning to the circular economy means finding alternative sources of biobased and renewable raw materials, as well as extending the functionality of the materials in paints and coatings after their use and promoting the recycling of waste paints.”īeyond the environmental advantages, there are additional benefits of waterborne coatings that create incentives for switching from solvent-based systems. “The finite supply of petroleum and titanium ore, and the increased carbon footprint associated with processing them into polymers and white pigments for use in paints and coatings, is an environmental issue that needs to be solved by all members of the industry’s value chain,” says Melanie Bauer, global marketing director for Coatings at Michelman. On a more granular level, consumers are more aware of the long-term impact that products are having on the environment, which is driving the coatings industry to develop more sustainable paints and coatings from partially or wholly biobased and renewable raw materials. “Initiatives to help create safer and more sustainable products are an industry responsibility and always at the forefront of innovation,” agrees Marc Chan, regional marketing manager for Industrial Applications with Clariant.
For example, there is movement in China today as the government introduces stricter regulations, but ultimately, the overarching driver is the desire to improve human health and air quality by reducing emissions-all without compromising on the desired protection that a coating should deliver, explains Monet Talesara, global segment leader for GIF/PC at Dow Coating Materials.
“What started as regionally limited projects with the aim of reducing emissions in living spaces, has since become a global movement that has spread out to virtually all areas of application,” says Petra Lenz, technical support manager for Paint Additives at BYK. The overall rising interest in sustainability, which manifests in the form of stricter environmental regulations and growing customer/consumer demand for more environmentally friendly products, is the key driver for adoption of waterborne paints and coatings and advancement of resin, additive, and pigment technologies used in their formulation. The global waterborne coatings market was valued at $73.19 billion in 2017 and predicted to expand at a compound annual growth rate of 5.0% from 2018 to 2026, according to Transparency Market Research.
