Coating filtration can be one of the most complicated liquid-particle separations because the base product is mixed using various components, while others must be removed. This applies to paints, lacquers, inks, varnishes, finishes and sealants.
While creating top-quality coatings begin with using the best raw materials, filtration is still key to its end quality - even a single fibre or speck of dust can cause poor quality end products. That's because even the raw materials (water, oil, emulsions, resins, additives) need to undergo filtration before they are added to the mix.
Other impurities can also be trapped or created throughout the production process. For example, some ingredients when left along in certain temperatures can produce a layer of skin or film that will form lumps if mixed with the rest of the product. Liquid filtration ensures the removal of large particles, dust, film, sediments, and left over pigments. This helps to reduce haze and improve product clarity, produce consistent textures, and maintain good adherence when applied.
