Superior Anti-Caking at High Loadings
Industrial coating formulations demand matting agents that perform at the extreme end of the loading curve. HMMAT 300 Series features a specially modified surface that prevents hard-cake formation and agglomeration even at 8–15 wt% loading in high-PVC industrial primers — eliminating the batch-to-batch gloss streaking that plagues conventional silica at heavy DFT.
Robust Performance in Epoxy and Polyurethane Systems
Anti-corrosion primers based on epoxy-amine and polyurethane-isocyanate binders are chemically aggressive toward conventional surface treatments. HMMAT 300's advanced modification is engineered to resist amine attack and isocyanate reactivity, maintaining particle integrity and matting efficiency through the full pot life of two-component industrial systems, from mixing through application to final cure.
Consistent Gloss Control at 40–100 µm DFT
Heavy protective coatings operate in a DFT range where most matting agents lose repeatability. HMMAT 300 delivers ±2 GU batch consistency at 60° gloss measurement across the 40–100 µm DFT window typical of steel structure, offshore, and industrial equipment coatings. OEM industrial paint brands achieve specification conformance on every production run without reformulation.
FCL Supply for Continuous Production Lines
Industrial paint manufacturers running anti-corrosion lines, maintenance product ranges, or protective topcoat systems cannot afford spot-supply volatility. SEMITECH delivers HMMAT 300 in locked-spec FCL orders with fixed particle size windows, private-label packaging, and multi-port FOB options — Shanghai, Ningbo, or Tianjin — ensuring your production schedule is never held hostage to supply unpredictability.

Grade Selector for Industrial Coatings
HMMAT 300 Series is the primary recommendation for heavy DFT industrial systems. HMMAT 200 covers thinner industrial topcoats where clarity is additionally required.
| Grade | d50 / Treatment | DFT Range | Application Fit |
|---|---|---|---|
| HMMAT 300 (std) | 6–8 µm / special mod | 40–80 µm | Epoxy primer, steel structure topcoat |
| HMMAT 300 (coarse) | 9–12 µm / special mod | 60–100 µm | Heavy maintenance, offshore topcoat |
| HMMAT 255 | 5.5 µm / wax | 20–40 µm | Thin industrial topcoat requiring clarity |
| HMMAT 270 | 7 µm / wax | 30–50 µm | Mid-build industrial finishes |
Technical FAQ
Heavy DFT industrial coating formulation challenges and HMMAT 300 performance answers.
+Why is anti-caking performance critical for heavy DFT industrial coating matting agents?
Heavy DFT industrial coatings typically run at high silica loadings (5–15 wt%) to achieve target gloss reduction in films 40–100 µm thick. At these loadings, conventional silica can form hard cakes during storage or agglomerate in the mixing vessel. HMMAT 300 Series features superior anti-caking modification that maintains free-flow handling and ensures homogeneous dispersion even at high pigment volume concentrations.
+How does HMMAT 300 perform in solvent-borne epoxy anti-corrosion primers?
HMMAT 300 Series is specifically modified to disperse cleanly in high-polarity epoxy systems with amine hardeners. The surface treatment is stable against amine attack, maintaining particle integrity and matting efficiency throughout the full pot life. Gloss control in epoxy primers at 60–100 µm DFT is reproducible within ±2 GU batch to batch.
+What gloss levels can be achieved with HMMAT 300 at typical heavy DFT loadings?
At 60° gloss measurement, HMMAT 300 Series achieves 10–30 GU at loadings of 5–10 wt% in a standard 60 µm DFT epoxy or polyurethane industrial topcoat. For deep matte finishes below 10 GU, loadings of 8–15 wt% are typical. The anti-caking modification ensures these high loadings disperse without agglomerate streaking.
+Is HMMAT 300 suitable for maintenance coatings applied by airless spray in the field?
Yes. HMMAT 300 is designed for robust performance under variable field application conditions. Its free-flowing powder form mixes readily in single-drum batch preparation, and the anti-caking modification tolerates the temperature and humidity fluctuations typical of on-site maintenance work. Airless spray atomisation is not adversely affected at standard application viscosities.
+What certifications and test documentation accompany HMMAT 300 FCL shipments?
Every HMMAT 300 FCL shipment includes a batch-specific CoA covering particle size, oil absorption, pH, moisture, and BET surface area; an SDS/MSDS; a REACH SVHC compliance declaration; and an ISO 9001 quality statement. Third-party test reports from SGS or Intertek can be arranged for first-shipment qualification audits.
