The HMMAT UV Series is our OEM bulk-supply line of non-wax silica matting agents engineered for downstream UV-curable coating and ink manufacturers. Identical chemistry to the GMATT UV retail line — the same proprietary non-wax surface treatment that prevents PE wax migration in 100%-solid systems — supplied under contract with 25 MT FCL minimums and private-label packaging. Built for downstream UV-coating OEMs serving wood, plastics, and 3C electronics markets.
Key Features
- Critical for Downstream UV OEMs: Non-wax chemistry eliminates the inter-coat adhesion risk that downgrades downstream UV brand reputation.
- Contract-Grade Consistency: Locked oil absorption window (130-200 g/100g) across FCL lots — downstream viscosity stability guaranteed run-to-run.
- Audit-Traceable Special Treatment: Each FCL ships with mother-batch COA confirming the proprietary non-wax modification.
- High Transparency: Optimized refractive index maintains the natural depth of wood substrates in downstream brand finishes.
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 annual contracts (100+ MT/year typical for UV-coating OEMs)
- Audit-Ready: ISO 9001 + REACH + 21 CFR 175.300 (for UV-cured food-contact coatings)
- Just-In-Time Program: Quarterly call-off with locked annual pricing
- Multi-Port Shipping: Shanghai, Ningbo, Tianjin FOB; CIF terms negotiable
Applications
Trusted by leading UV-coating downstream OEMs across:
- 100% Solid UV Wood Coatings (Roller & Spray)
- UV Curable Inks & Overprint Varnishes (OPV)
- UV Plastic Coatings (3C Electronics)
- Waterborne UV (WB-UV) Systems
HMMAT UV Series: Grade Selector
UV systems require precise particle size matching. Select the grade based on your downstream customer's Dry Film Thickness (DFT) and application method.
| Grade | Spec | Recommended DFT | Notes |
|---|---|---|---|
| HMMAT U700 | d50 7.0 – 7.5 µm | 15 – 25 µm (Thin/Medium Film) | Ideal for thin-film UV spray coatings and OPV. Delivers exceptional transparency and a smooth, refined touch. Minimal viscosity impact. |
| HMMAT U750 | d50 7.5 – 8.0 µm | 25 – 30 µm (Medium Film) | The versatile standard for UV wood coatings. Perfect balance between high matting efficiency and anti-settling performance. |
| HMMAT U800 | d50 8.0 – 8.5 µm | > 30 µm (Thick Film) | Designed for heavy-duty UV roller coatings and thick primers. Provides strong matting power, excellent scratch resistance, and robust suspension. |

OEM Procurement Workflow
- Spec & Volume Brief: Submit target d50, downstream UV system (wood / plastic / OPV / WB-UV), and annual or per-FCL volume.
- Sample Match: 1 kg lab match shipped within 5 days; downstream QC verifies non-wax behavior in your monomer system; sign-off triggers contract drafting.
- First FCL Contract: 25 MT pilot shipment under your private label, full COA chain + non-wax certification per batch, ISO + REACH + 21 CFR dossier delivered.
- Repeat Replenishment: Scheduled call-off (quarterly typical for UV-grade volumes) with locked-in annual pricing.

Frequently Asked Questions
Common questions from UV-coating OEM procurement teams.
+Can HMMAT UV be private-labeled while protecting the non-wax IP?
Yes. The non-wax surface-treatment chemistry is our IP; your brand appears on the packaging, and the COA discloses the property values your downstream brand customers and their formulators need (oil absorption, d50, pore volume) without revealing the underlying treatment chemistry.
+What is the minimum FCL order and lead time for UV-grade silica?
Minimum is 1 × 20-foot FCL (~20 MT non-wax UV-grade silica). Lead time is 30-40 days for a first private-label run (non-wax grades require dedicated mother-batch staging); 20-25 days for repeat orders under an active contract.
+Do you support audits from our downstream UV-coating brand customers serving food packaging?
Yes. UV-coating brands serving food-packaging applications (OPV, can coatings) routinely require 21 CFR 175.300 documentation. We provide full migration-test data and host downstream brand audits at our Shanghai plant under NDA.
+How is non-wax behavior verified per batch?
Every HMMAT UV FCL ships with a non-wax verification certificate from our QC lab, confirming the absence of free PE wax via DSC and migration testing. This is critical for downstream UV brands that have been burned by mislabeled "wax-free" alternatives.
