What is High Solids Coatings?
Imagine a world where paint isn’t just paint but a thick, robust guardian of every surface it adorns. That’s the realm of high solids coatings. High solids coatings may also be called high solids formulations. High solids coatings are defined as one- or two-component coatings, a paint that is formulated with a higher resin concentration and lower volatile organic compound (VOC) concentration. Of course, high-solids paints can be solvent-based or water-based. , but its formulation has a higher concentration (at least 65%) of solid components (base, pigments and additives) than traditional coatings and maintains satisfactory effects or application performance.
Please note: While there are no requirements for solids content in coatings, higher solids content generally means lower solvent content, resulting in reduced VOC emissions. In contrast, solvent-based coatings are often cited as a major source of harmful VOCs. High solids products are being developed by coating manufacturers in response to stricter environmental regulations. This is despite lowering the percentage of volatile organic compounds (VOCs) to accommodate modern and increasingly stringent regulations.

What the Difference Between High Solids and Low and Midium Solids Coatings?
In the vibrant world of coatings, where every shade and sheen has its own secret story, a particularly interesting story unfolds between high-solids coatings and less concentrated low- and medium-solids coatings. These paints differ not only in color, but also in the essence of their existence. Next, let us understand the differences between them in terms of solid content, drying process and thickness difference.
- Solids content:
These are the heroes of our story. High solids generally refers to coatings formulated with higher resin concentrations and lower volatile organic compound (VOC) concentrations. High-solids paints are composed of at least 65% solids, with some of the top high-solids paints having as much as 100% solids content. These solid ingredients include base materials, pigments and additives. High solids content means less solvent is required, making these coatings guardians of efficiency and environmental stewardship.
Low and midium solids coatings, on the other hand, are specially formulated to contain more solvents. This increased solvent concentration makes the construction process easier and cheaper to manufacture. Typically, low solids means less than 30% solids; medium solids ranges from 30% to 65% solids.
- Drying process:
Because High solids coatings have lower solvent content, less evaporation occurs, which not only speeds up the curing process but also reduces volatile organic compound (VOC) emissions. It’s like an eco-magic trick, the coating transforms quickly while being kind to the environment (our environment).
And low solids and medium solids coatings: These coatings require a longer description of their drying and curing process. The drying process is a gradual process, unfolding layer by layer as more solvent evaporates. This slower rate of evaporation is similar to traveling a long distance, taking time to reach your destination (fully dry and hard) and emitting more emissions along the way. - Thickness variation:
The difference between the initial application and the thickness of the coating after curing is called the wet thickness (WT) and dry thickness (DT) of the coating. Since solvent coatings evaporate more components after application, the coverage thickness of the coating is significantly less than that of high solids coatings. An example will give you the idea: For a 40% medium solids coating it will take 2 coats to achieve the same level of thickness as a cured coat of an 80% high solids coating.
High solids and low to medium solids coatings both have their place in the coatings world, and each has its own advantages and challenges. Whether you are pursuing environmental protection or convenience, the coating field can meet your various needs.
Why is a High Solids Coatings a Good thing?
Now, let’s summarize the benefits of choosing high solids coatings. See if its product advantages match your project needs.
- Environmental Friendliness: The main advantage of high solids coatings is their ability to meet environmental standards for solvent-based paints. To address worsening air quality, the Environmental Protection Agency (EPA) in the United States has implemented a law limiting the amount of volatile organic compounds (VOCs) or diluents/solvents emitted into the atmosphere. High solids coatings are a new type of paint that complies with EPA emission regulations.
- Ease of Application:In situations where water-based coatings are inconvenient, high solids coatings offer the convenience of solvent-based coatings while meeting environmental requirements.
- Thickness Control: As mentioned earlier, high solids coatings have significantly lower evaporation losses after curing compared to low and medium solids coatings. Thanks to their increased solids content, high solids offer some important benefits:Less evaporation during the drying process, making the finish brighter and more opaque. Better coating coverage. Low coating consumption. Therefore, during application, high solids coatings are easier to reach the target coverage thickness.
- Convenience of Application:A major advantage of high solids coatings is that they do not require multi-step pre-treatment cleaning and painting processes. Of course, proper surface treatment is still necessary to ensure the long-term success of metal coatings.
How to Spray High Solids Coating?
Spraying is the primary application technique for high solids coatings once the surface of the object to be coated has been pretreated. Due to the high viscosity of these products, spraying can pose some challenges. The higher the solids content, the more difficult it is to apply the right amount of coating.
Painters using high solids paints need to follow the correct process, as incorrect application can negatively impact the quality and appearance of the final product. There is a higher risk of improper film thickness or even unpainted spots when applying paint in one layer. Therefore, it is recommended to apply a stripe coat at weld seams, corners, and other problematic areas before applying the full coating.
You also need to ensure that the spraying equipment and air supply are clean and free of contaminants. You can use higher air pressure to achieve the correct atomization effect for high solids coatings.
Step-by-Step Guide to Spraying High Solids Coating:
- Prepare the Surface: Ensure that the surface to be coated is clean, dry, and free of any contaminants. Sanding or chemical cleaning may be necessary to achieve the desired surface condition.
