IMSIL
Microcrystalline Silica
IMSIL microcrystalline silica fillers are produced from an inert, naturally occurring alpha quartz with a unique grape-like morphology. We produce several grades of IMSIL, which impart different properties to paints and coatings. Finer micronized grades are useful in formulating higher gloss paints and systems requiring controlled particle top size, such as industrial OEM topcoat coats and non-conductive inks. Intermediate size grades offer ideal and uniform gloss control for topcoats, coil coats and increased inter-coat adhesion between primers and topcoats. Coarser grades offer high solids loading with low viscosity, texture, anti-skid and abrasion resistance in industrial floor coatings and exterior deck coatings.
Product Highlight
IMSIL is made from alpha quartz, the most common of the silica polymorphs and the most stable form of solid silicon dioxide at room temperature. It is highly inert to strong acids and bases, and when microcrystalline quartz is used as a functional filler, this property gives paints and coatings chemical resistance. Alpha quartz crystals resemble grape-like clusters that are easily dispersed in water- and solvent-based formulations. The crystals’ consistent surface area allows uniform oil absorption. Microcrystalline silica fillers and extenders also add resistance to abrasion to coatings and are useful in industrial applications.

Attain outstanding adhesion between primers and topcoats with IMSIL.
IMSIL enhances color and gloss retention, even over prolonged exosure to environmental factors, ensuring a vibrant and glossy appearance over time.
Interior decorative paints
IMSIL adds many valuable qualities when used as a paint filler for interior blends. These include ease of tinting for deep bases, scrub and stain resistance, gloss control and burnish and blocking resistance.
Exterior decorative paints
In exterior decorative paints, IMSIL grades can be used to improve UV resistance, ease of tinting and resistance to yellowing, efflorescence and rain marking. Finely micronized grades of IMSIL are useful in formulating high gloss paints, ensuring a lasting and beautiful finish.
Industrial/Marine exterior applications
IMSIL is a valuable addition to industrial and marine protective coatings, offering outstanding chemical resistance for enhanced durability and corrosion protection. It enhances protection from abrasion, UV damage and chemical damage.
Roof coatings
Incorporating IMSIL microcrystalline silica filler into roof coatings not only enhances UV resistance but also significantly boosts the reflectivity of the surface, effectively reducing heat absorption and extending the lifespan of the roof.
Floor coatings
When used in floor coatings, IMSIL provides a dual benefit by greatly enhancing both abrasion and scratch resistance, as well as chemical resistance, ensuring long-lasting durability and protection for high-traffic areas.
Wood coatings
In wood coatings, IMSIL delivers improved chemical resistance, clarity, gloss control, and superior stain resistance, enhancing the finish quality and longevity of wood surfaces.
Road markings
With high abrasion resistance and UV and chemical resistance, ISMIL is an excellent choice for road-marking paints.
Sealants and adhesives
In sealants and adhesives, the integration of IMSIL microcrystalline silica filler greatly improves resistance to chemicals, offering enhanced durability.
