10 LBS Assay Silica Flour/Sand 400 Mesh
Assay Silica Flour is engineered for ultra-fine consistency in coatings and industrial formulations. The 10 LBS Assay Silica Flour/Sand 400 Mesh delivers exceptional fineness and uniformity, featuring a 40-micron particle size and a bright white, low-moisture SiO2 blend that remains inert across applications. This makes it ideal for precision work in coatings, polymers, sealants, and specialty composites.
This premium silica flour is at least 99.2% SiO2, providing reliable, non-reactive performance in paints, coatings, sealants, ceramics, and composites. Its 400-mesh sizing ensures even dispersion and minimal sedimentation, helping you achieve smoother finishes and consistent color in every batch. The bright white tone helps minimize tinting in clear or light-colored formulations, while the low moisture content improves shelf life and processing stability.
