HY11H Indoor, Smoke-Free Physical Matting Agent

Overview

Matting agent HY11H is an internally balanced reactive matting agent (commonly known as a physical matting agent) that does not consume epoxy resin from the substrate matrix. It is suitable for hybrid polyester/epoxy systems in ratios of 5:5, 6:4, and 7:3, exhibits broad compatibility with polyesters, and requires low addition levels. The agent delivers excellent coating appearance quality, antiyellowing properties, and mechanical performance. Its fumefree characteristic meets the requirements of environmentally conscious customers.

Typical Properties

Grade: Industrial
Appearance: Milkywhite or lightyellow powder
Solid Content: ≥98%

Product Application

Add 1–3% (by total formulation weight) of the matting agent and blend it evenly with other raw materials before co‑extrusion. The powder can then be manufactured following standard production processes. The optimal dosage should be determined through practical testing.

Product Characteristics

• Compatible with polyester/epoxy powder coatings achieving a 60° gloss of 8 GU or higher.

• Delivers excellent performance, low dosage, reduced gloss, and outstanding cost-effectiveness.

• Provides a very fine, smooth coating surface with excellent yellowing resistance and mechanical properties.

• Does not consume epoxy, functions via physical matting, and offers broad applicability with wide compatibility across polyester resins.

Friendly Reminder

1．Process Control

Optimize powder production by ensuring fast extruder feeding and low extrusion temperatures to maintain consistent matting performance.

2. Raw Material Compatibility

Gloss levels may vary with fillers, polyesters, and dosage from different suppliers. The matting agent should be carefully matched with other formulation components.

3. Promoter Addition

Adding a moderate amount of curing promoter can improve impact strength but may increase gloss or affect leveling.

4. Dosage and Reactivity

Higher matting agent dosage increases reactivity, shortens burn time, lowers gloss, and may affect powder storage stability. Reactivity varies with polyester type; adjust formulation accordingly and verify storage performance. Conduct tests before scaling up.

5. Quality Assurance and Disclaimer

While the matting agent may deliver favorable results, variations in application conditions, polyester selection, production processes, and commercial factors require continuous quality control. Sample and test every 500 kg during continuous production. On‑site trials by end‑users are strongly recommended.
