(July 29, 2026)The green transformation of coatings and ink industry accelerates, and special modified silica ushers in structural demand growth. As domestic VOC control policies are continuously implemented, waterborne coatings, UV-curable coatings and powder coatings are gradually replacing traditional solvent-based products. Silica performs multiple functions in the system including matting, rheology control & anti-sagging, anti-settling, wear resistance and reinforcement. As end users continuously raise requirements on film transparency, matte texture and storage stability, general powder is gradually replaced by segmented special grades. The coatings sector has become the core growth segment of silica outside the rubber industry.
For a long time, the application of silica in the coatings industry presents obvious hierarchical differences. Low-end architectural coatings widely adopt economical precipitated silica merely to meet basic anti-settling requirements. High-end wood varnish, industrial anti-corrosion coatings, printing inks and leather finishing systems impose strict standards on powder particle size distribution, dispersibility and impurity content. Ordinary silica is prone to agglomeration, leading to increased haze, uneven gloss and storage delamination of coating films. Ultra-fine silicon dioxide with directional surface modification can disperse evenly in various resin systems such as waterborne, solvent-borne and UV resins. It can accurately adjust matte effect, balance film transparency and friction resistance, improve coating workability and avoid sagging during spraying.
In the second half of 2026, rising home renovation demand and recovering industrial manufacturing push up the operating rate of coating factories. Leading coating enterprises accelerate the waterborne upgrading of product lines and expand production capacity of eco-friendly coatings. Orders for export-oriented inks and coil coatings pick up steadily. Overseas customers carry out stricter inspections on raw materials concerning carbon footprint, heavy metal limits and REACH compliance certificates. Many silica manufacturers adjust product layout and boost the R&D and mass production of modified silica dedicated to matting agents and rheology additives. Differentiated products are developed for wood coatings, automotive coatings and digital printing inks. Some enterprises carry out joint formula testing with coating research institutes, adjust surface functional groups of powder according to resin polarity, and provide customized filler solutions for downstream clients.
Diverse coating systems generate differentiated indicator requirements. Waterborne architectural coatings prioritize hydrophilic modified silica with outstanding dispersion stability and scrub resistance; high-end wood varnish requires narrow-particle-size matting silica featuring low haze and delicate matte texture; UV-curable printing inks set strict limits on powder moisture content and reaction activity; heavy-duty anti-corrosion industrial coatings adopt nano silica to enhance coating compactness and water vapor barrier performance. A single universal grade can hardly adapt to various resin systems, pushing enterprises to build diversified product portfolios and abandon homogeneous low-price competition. Downstream coating enterprises continuously raise supplier screening thresholds. Apart from physical and chemical indicators, tests on long-term storage stability and weathering aging are added, extending the certification cycle for new products.
The track boasts considerable growth potential while market competition conflicts become prominent. The production of ultra-fine modified silica for high-end coatings requires precise process control, and purification & modification procedures bring relatively high costs. Overseas brands have long occupied supply chains of high-end varnishes and imported inks. A large number of small and medium-sized domestic manufacturers focus on general precipitated silica and seize low-end markets via low prices, disturbing the price system. Meanwhile, cyclical price fluctuations of upstream raw materials such as water glass and sulfuric acid continuously squeeze profit margins of small and medium powder manufacturers.
The supply-demand differentiation pattern keeps emerging. Leading enterprises equipped with fine modification processes, complete testing laboratories and formula technical support achieve steady growth of high-end orders. Manufacturers only capable of producing ordinary powder without application R&D capacity can only compete in low-margin low-end markets. The coatings industry accelerates concentration, and orders continuously converge to raw material suppliers with stable quality control and complete compliance certificates.
Industrial research institutes analyze that the penetration rate of eco-friendly coatings will keep rising within the next three years, and demand for functional silica in coatings and inks will maintain steady growth. Compared with the fiercely competitive tire track, special silica for high-end coatings delivers higher added value, serving as an important direction for enterprises to optimize revenue structure.
In the long run, deploying modified silica dedicated to coatings and inks helps expand downstream market boundaries and mitigate operational risks caused by cyclical fluctuations of the single rubber industry. Domestic silica enterprises shall continuously deepen core technologies of particle size regulation and surface modification, segment product series for different coating scenarios and complete various domestic and international environmental compliance certifications. Strengthen upstream and downstream collaborative R&D with coatings and ink manufacturers, accelerate import substitution of silicon dioxide for high-end coatings, and consolidate the competitive advantages of China’s silicon-based powder in the field of fine chemical new materials.
