The HMMAT 200 Series is our flagship OEM bulk-supply line of wax-treated silica matting agents for downstream wood-coating and coil-coating brands. With identical chemistry to the GMATT 200 retail family but supplied exclusively under contract terms with 25 MT FCL minimums, HMMAT 200 is built for downstream OEMs who need predictable monthly tonnage with their own brand on the bag.
Key Features
- Contract-Grade Consistency: Locked d50 window (±0.2 µm) across FCL lots — qualified for downstream automated dispersion lines.
- Audit-Traceable Lots: Every drum stamped with mother-batch ID, single ISO 9001 plant of origin.
- High Clarity: Optimized refractive index; no hazing on dark finishes.
- Anti-Settling: Advanced wax-treated surface prevents hard caking — critical for 90-day downstream warehouse holding.
OEM Capabilities
- Private-Label Packaging: Your brand sleeve on 20 kg bags or 500 kg bulk bags
- Custom MOQ: 1 FCL (20 MT) entry to multi-FCL annual contracts (200+ MT/year)
- Audit-Ready: ISO 9001 + 21 CFR 175.300 (wax-treated grade approved) + REACH dossier
- Just-In-Time Program: Monthly call-off scheduling with locked pricing
- Multi-Port Shipping: Shanghai, Ningbo, Tianjin FOB; CIF terms negotiable
Applications
Trusted by major OEMs across:
- Premium Solvent-based Wood Coatings (Clear & Pigmented)
- Coil Coatings
- General Industrial Baking Enamels
- Leather Finishes
HMMAT 200 Series: Grade Selector
Match the grade to your downstream customer's Dry Film Thickness (DFT) target. Gradient particle sizes (4.0–9.5 µm) cover thin to thick-film systems.
| Grade | Spec | Recommended DFT | Notes |
|---|---|---|---|
| HMMAT 240/245 | d50 4.0 – 5.0 µm | < 15 µm (Ultra-thin) | For leather and thin-film coatings. Provides a silky smooth touch. |
| HMMAT 255/260 | d50 5.0 – 6.5 µm | 15 – 25 µm (Thin) | Premium wood clear coats & 3C coatings. High transparency, zero hazing. |
| HMMAT 270 | d50 7.0 – 7.5 µm | 25 – 35 µm (Medium) | General industrial & coil coatings. Best overall matting efficiency. |
| HMMAT 285/290 | d50 8.5 – 9.5 µm | > 35 µm (Thick) | Heavy-duty, floor & thick wood primers. Maximum matting & recoatability. |

OEM Procurement Workflow
- Spec & Volume Brief: Submit target d50, oil absorption window, packaging preference, and annual or per-FCL volume forecast.
- 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 (monthly/quarterly) or VMI program with locked-in annual pricing.

Frequently Asked Questions
Common questions from OEM procurement teams and downstream brand customers.
+Can HMMAT 200 be private-labeled with our brand?
Yes. Full private-label packaging is standard for HMMAT contracts — your brand, your grade name, your regulatory text. We retain only the country-of-origin and CAS-number labeling required by export regulation.
+What is the minimum FCL order and lead time?
Minimum is 1 × 20-foot FCL (~20 MT of wax-treated 200-series silica). Lead time is 25-35 days for a first private-label run (includes packaging artwork approval); 15-20 days for repeat orders under an active contract.
+Do you support audits from our downstream brand customers (e.g., automotive OEMs, furniture majors)?
Yes. Our Shanghai and Mingguang plants are ISO 9001 certified and routinely host audits from European, North American, and Japanese coating customers including audits by their downstream automotive and furniture OEMs. Full process documentation available under NDA.
+What lead time should we plan for repeat orders under a contract?
Active-contract repeat orders typically ship 15-20 days from call-off PO. With a VMI program, we can hold safety stock at our Shanghai bonded warehouse for 7-day pull lead times.
