Industries We Serve.

Automotive OEM topcoats demand consistent gloss at 30–40 GU with zero surface defects across high-speed spray lines. GMATT 200 Series (d50 = 5–7 µm) delivers the narrow particle distribution needed to avoid orange peel in 2K PU clearcoats cured at 80–140°C. For refinish markets, where batch-to-batch color matching is critical, the low oil absorption (≤220 mL/100g) minimizes impact on TiO₂ loading and recoat adhesion. Interior trim coatings targeting soft-touch matte finishes below 10 GU rely on GMATT 300 Series at 3–5% loading. See full automotive specs →

Furniture manufacturers specify matte and satin finishes (10–25 GU at 60°) that must survive daily abrasion without burnishing. GMATT 100 Series gel-type silica at 3–6% w/w in UV-curable and acid-catalyzed lacquers provides anti-burnish performance rated >500 cycles (DIN 68861-2). The 6–8 µm median particle size avoids the hazy appearance that finer grades produce on dark wood stains. For waterborne furniture systems gaining share in EU markets under VOC Directive 2004/42/EC, GMATT WB Series maintains dispersion stability at pH 7.5–9.0 without thickener reformulation.### Architectural & Construction Coatings

Architectural coatings cover the largest volume segment — exterior facades, interior wall paints, and floor coatings all requiring controlled sheen at competitive cost. GMATT 600 Series precipitated silica (d50 = 8–12 µm, oil absorption 180–250 mL/100g) is the workhorse here, achieving 20–40 GU in acrylic emulsions at 1.5–4% loading. For premium interior flat paints below 5 GU, GMATT 100 Series at higher loading (5–8%) delivers dead-matte without the chalky surface feel that diatomaceous earth alternatives produce. Scrub resistance exceeds 10,000 cycles (ASTM D2486).### Industrial Maintenance, Marine & Packaging

Industrial maintenance coatings for chemical plants and offshore structures face UV exposure, salt spray, and thermal cycling from −30°C to 200°C. GMATT 200 Series in epoxy-polyamide primers maintains 25–35 GU after 3,000 hours salt spray (ASTM B117) without silica settling. Marine antifouling topcoats use coarser GMATT grades (10–12 µm) to avoid interference with biocide release kinetics. In packaging coatings — can linings, flexible film overprint varnishes — the low heavy-metal content (<10 ppm Pb) and FDA-compliant grades meet food-contact requirements under 21 CFR 175.300.

China's furniture export sector relies on NC, PU, and UV lacquers that must achieve 10–25 GU satin and matte finishes under GB 18581-2020 VOC compliance requirements. GMATT 200 and 300 Series at 3–6% w/w provide reliable anti-burnish performance across both solventborne and waterborne systems, maintaining gloss stability after 1,000+ abrasion cycles without silica settlement. The d50 = 5–8 µm particle range ensures compatibility with high-build UV topcoats and spray-applied PU sealers used in automated furniture finishing lines. See full furniture specs →

Thin-film overprint varnishes (OPV) and flexible packaging coatings demand ultra-fine matting agents that do not disrupt print clarity or ink adhesion. GMATT 100–240/245 with d50 ≤5 µm achieves 5–15 GU in flexible packaging substrates at 1.5–3% loading while maintaining FDA 21 CFR 175.300 food-contact compliance with heavy metals below 10 ppm Pb. The narrow particle distribution prevents clogging in gravure and flexo coating heads at line speeds above 200 m/min. See full packaging specs →

Matte varnish overcoats and gravure/flexo/digital ink systems require dual-function additives that control gloss while managing rheology. GMATT 100 Series at 2–4% loading targets 10–30 GU in matte varnish topcoats, while SEMISIL H100 fumed silica at 0.5–1.5% simultaneously builds thixotropic structure that prevents ink bleed and sagging on non-absorbent substrates. In lamination varnishes, GMATT 100's treated surface chemistry provides anti-blocking properties critical for roll-to-roll processing without adhesion loss at the lamination bond line.

Military and commercial aerospace topcoats formulated to MIL-PRF-85285 require matting agents that withstand extreme thermal cycling from −55°C to 200°C without gloss shift or particle delamination. GMATT 200 Series in chemical-resistant polyurethane topcoats delivers consistent 25–35 GU after 3,000 hours salt spray (ASTM B117) and retains appearance after fluid immersion in hydraulic fluids, Skydrol, and jet fuel. The low oil absorption (≤220 mL/100g) preserves the high-solids formulation space required to meet aerospace VOC specifications. See full aerospace specs →

Epoxy and PU floor coating systems applied at 60–150 µm DFT demand matting agents that survive heavy forklift traffic, chemical spills, and daily cleaning without gloss degradation. GMATT 300 Series (grades 285/290, d50 = 9–11 µm) at 2–5% loading achieves controlled 20–40 GU satin finishes in solventborne and 100% solids epoxy systems, with particle morphology contributing to DIN 51130 R10–R11 anti-slip ratings in safety-critical zones. Chemical resistance to industrial cleaning agents and caustic solutions is maintained after 500 hours immersion per ISO 2812-1. See full floor coatings specs →

Luxury cosmetics packaging lacquers applied to glass, ABS, and PET substrates require flawless satin and matte finishes at 10–30 GU with zero particle protrusion, fisheyes, or surface defects at the 0.1 µm inspection level. GMATT 100–240/245 with d50 ≤5 µm delivers the ultra-smooth matting performance needed for high-gloss-to-matte transitions on premium skincare and fragrance bottles, fully compatible with ISO 22716 GMP cosmetic manufacturing requirements. Loading levels of 1–3% in UV-curable and solventborne packaging lacquers preserve color accuracy and DOI (distinctness of image) on metallized and pearlescent substrates. See full cosmetics packaging specs →

ISO 12944 C5-M and Im2 corrosion category topcoats for vessels, offshore platforms, and port structures demand matting agents that maintain structural integrity under continuous salt water immersion and UV weathering. GMATT 200 Series in epoxy and polyurethane marine topcoats sustains 25–35 GU after 3,000 hours ASTM B117 salt spray and 2,000 hours UV weathering (ASTM G154), with no silica agglomeration that would compromise coating barrier properties. Coarser GMATT grades contribute to deck non-slip surface texture while remaining compatible with antifouling biocide packages. See full marine specs →
