Sterling Chemicals manufactures Microtec Colloidal Silica—precision-grade, high-volume, and customizable to exact process specifications.
PrimaryIndustrial Pillars
Engineered colloidal silica solutions tailored for paper, coatings, and construction applications. Enhancing performance, durability, and process efficiency across critical industrial operations.
Paper & Pulp: Retention and Drainage
Trusted by global leaders like Solenis and Buckman, Microtec is engineered to optimize the wet-end chemistry of modern papermaking.
Our silica acts as a high-efficiency retention aid, improving fibre and filler retention while accelerating drainage on the wire.
We control the particle size distribution to ensure maximum surface area activity, leading to better formation and reduced chemical costs.
Enhances surface strength and ink receptivity for specialty and high-quality coated papers.
Paints & Specialty Coatings
In the coatings industry, Microtec is the "invisible" ingredient that transforms durability and aesthetics.
Increases the mechanical strength of coatings without compromising transparency.
Creates a high-energy surface that repels dust and environmental pollutants, keeping architectural coatings cleaner for longer.
Improves the bond between the coating and difficult substrates, including metal and glass.
High-Performance Construction
For the construction industry, we offer Microtec as a high-activity pozzolanic agent for next-generation concrete.
Microtec reacts with Calcium Hydroxide to create additional C-S-H gel, filling capillary pores and drastically reducing permeability.
Ideal for liquid floor hardeners and concrete polishing, providing a dust-proof, high-gloss finish.
Enhances early-age strength development in high-performance and ultra-high-performance concrete (UHPC) mixes.
