The HMMAT 300 Series is our OEM bulk-supply line of specially modified silica matting agents for downstream industrial-coating and UV-coating manufacturers running heavy-DFT systems. Identical chemistry to the GMATT 300 retail line, but supplied under contract terms with 25 MT FCL minimums and private-label packaging — built for downstream OEMs who run multi-FCL annual programs.
Key Features
- Contract-Grade Suspension: Special surface treatment delivers superior long-term suspension in low-viscosity systems — critical for downstream tank-storage tolerance.
- Audit-Traceable Special Treatment: Each FCL ships with mother-batch COA confirming the proprietary modification — no substitution risk for downstream brand consistency.
- Excellent Recoatability: Unlike standard wax treatments, the special formulation guarantees zero loss of inter-coat adhesion in multi-layer downstream systems.
- Extreme Efficiency: High internal pore volume (≥1.8 ml/g) delivers maximum gloss reduction at minimum downstream dosage.
OEM Capabilities
- Private-Label Packaging: Your brand on 20 kg bags or 500 kg bulk bags
- Custom MOQ: 1 FCL (20 MT) entry to multi-FCL contracts (150+ MT/year)
- Audit-Ready: ISO 9001 + REACH + 21 CFR 175.300 dossier
- Just-In-Time Program: Quarterly call-off scheduling with locked annual pricing
- Multi-Port Shipping: Shanghai, Ningbo, Tianjin FOB; CIF terms negotiable
Applications
Trusted by leading downstream OEMs across:
- 100% UV-Curable Coatings
- Premium Solvent-based Wood Finishes
- High-end Industrial & Coil Coatings
- Leather and Thick-film Plastics Coatings
HMMAT 300 Series: Grade Selector
The HMMAT 300 Series is optimized for medium-to-heavy DFT systems. Match the grade to your downstream Dry Film Thickness (DFT) target.
| Grade | Spec | Recommended DFT | Notes |
|---|---|---|---|
| HMMAT 375 | d50 7.5 – 8.0 µm | 25 – 35 µm (Medium) | General-purpose grade for high-end wood and coil coatings. Perfect balance of matting efficiency, clarity, and smooth touch. |
| HMMAT 390 | d50 9.0 – 9.5 µm | > 35 µm (Thick) | Designed for high-build primers, heavy-duty industrial coatings, and thick leather finishes. Maximum matting power and scratch resistance. |

OEM Procurement Workflow
- Spec & Volume Brief: Submit target DFT range, downstream resin system (UV / solvent / hybrid), and annual or per-FCL volume.
- Sample Match: 1 kg lab match shipped within 5 days; downstream QC sign-off triggers contract drafting.
- First FCL Contract: 25 MT pilot shipment under your private label, full COA chain, ISO + REACH + 21 CFR dossier delivered.
- Repeat Replenishment: Scheduled call-off (quarterly typical for 300-series volumes) with locked-in annual pricing.

Frequently Asked Questions
Common questions from OEM procurement teams running 300-series volumes.
+Can HMMAT 300's special treatment be private-labeled while protecting the formulation IP?
Yes. The special-treatment chemistry is our IP and remains undisclosed; your brand appears on the packaging, and the COA discloses only the property values your downstream customers need (pore volume, oil absorption, d50). Full process IP stays at our plant.
+What is the minimum FCL order and lead time?
Minimum is 1 × 20-foot FCL (~20 MT of specially-treated 300-series silica). Lead time is 30-40 days for a first private-label run (special-treatment grades require longer mother-batch staging); 20-25 days for repeat orders under an active contract.
+Do you support audits and process documentation for our downstream brand customers running UV systems?
Yes. UV-coating brands (especially in flooring and furniture) increasingly require full process traceability. We provide a complete process-flow dossier, special-treatment confirmation per batch, and host downstream brand audits at our Shanghai plant under NDA.
+Lead time for first private-label run vs repeat orders?
First private-label run: 30-40 days including artwork approval and special-treatment mother-batch staging. Repeat orders under an active contract: 20-25 days from call-off PO. VMI options available for downstream OEMs running 100+ MT/year.
