IMSIL®
IMSIL®
IMSIL® microcrystalline silica fillers are produced from an inert, naturally occurring alpha quartz with a unique grape-like morphology. Easily wetted and dispersed in either solvent or water-based systems, IMSIL® is selected for its excellent tint retention, durability over prolonged exposure, and resistance to dirt and weathering.
Interior architectural paints formulated with IMSIL® will exhibit strengthened film integrity, increased stain resistance, more uniform sheen control, and excellent “touch-up” characteristics. Low oil absorption, regardless of particle size, enables formulators to increase loading without adversely affecting critical film properties. Exterior coatings containing IMSIL® will better resist weathering, chalking, and under eave frosting. When used in primers, this product also provides the “tooth” which is necessary for better intercoat adhesion and greater durability in abrasive or corrosive environments.
IMSIL® has proven effective in trade sales paints, OEM finishes, marine and industrial coatings, and potting compounds. Finer, micronized grades are useful in formulating higher gloss, and systems requiring controlled mineral top size, such as thin coatings and inks. Coarser grades offer texture, traction properties, gloss control, and abrasion resistance in coatings, grouts, sealants, and related building products.
