Coating composition for panels with stability in various temperatures
A recently filed patent (Publication Number: US20230279257A1) describes a coating composition for building panels. The composition includes several key ingredients such as calcium carbonate, titanium dioxide, an opacity pigment composite, calcined diatomaceous earth, calcium chloride, aluminum hydroxide, and vinyl acrylic polymer. The patent provides specific weight ranges for each ingredient, allowing for flexibility in formulation. For example, the calcium carbonate can be present in amounts ranging from about 20% to about 40% of the dry weight of the composition. Similarly, the titanium dioxide can range from about 10% to about 40%, and the opacity pigment composite can range from about 8% to about 30%. The patent also mentions the inclusion of a hydrophobic polymer emulsion, a wetting and dispersing additive, and an ethoxylated acetylenic gemini surfactant in smaller amounts.
The coating composition is intended for use on building panels, which can be coated on one or both surfaces. The method for applying the composition involves mixing the ingredients with a solvent, applying the mixture to the panel surface, and then heating the panel to evaporate the solvent and create a dry coating. The heating process can be done at temperatures ranging from 25°C to about 85°C.
Overall, this patent provides a detailed description of a coating composition for building panels, offering specific weight ranges for each ingredient and a method for application. The composition aims to provide a heat-stable coating that can enhance the appearance and durability of building panels.
