Filtration for Paints & Coatings

Paint filtration involves paints, oils, varnishes and lacquers that may be very thin and low-viscosity in nature, to very heavy, thixotropic liquids. The percent solids of a coating could vary from zero (when filtering solvents or water) to 100% solids, such as pure linseed oil. It is important to match the filter with the quality desired in the end product.


Have you also noticed that some paints peel or form craters after it dries, while others don't? That's because your paint might contain silicone. Silicone is a release agent and even minute amounts can make it less effective in sticking onto a surface.


Liquid filtration is essential to ensure that contaminants such as airborne particles, unmixed products or skins which have formed are removed. Unfortunately, using the wrong filter could cause silicone contamination. Threads on filter bags or fiber additives and dyes on filter media may contain silicones. Even lubricants on the filter media production equipment and cleaning materials may contain silicone.


We offer a series of depth, pleated, and specialty filters which are made for the paint and coating industries, where precautions are taken from the manufacturing stage to eliminate any sources of silicone. Click on the products below to download the data sheet.
