- Product Description
-
- Commodity name: HY28A Outdoor Matting agent
- 型号: HY28A
- 应用性能: <strong> Gloss: 8–60° </strong> <br /> Low-concentration addition of matting agent achieves low gloss levels. At a dosage of 3%, it achieves gloss levels below 20°, featuring good reproducibility, excellent yellowing resistance, fine surface texture, good mechanical properties, and wide polyester selection tolerance.
- 用法及用量: Added internally at 1-5%
HY28A Outdoor Matting Agent
Brief Description
HY28A Outdoor matting agent is specifically designed for polyester/TGIC powder coating systems (with micro-wax content). It is suitable for polyester-TGIC powder coatings with a gloss level of 8 or above (60°). It provides excellent film appearance, yellowing resistance, and impact resistance. The matting agent consumes TGIC at a ratio of 20:1, requiring minimal addition, which significantly reduces costs. It ensures stable gloss after repeated extrusion, offers good delayed impact resistance, has broad compatibility with polyesters, and is not sensitive to equipment temperature variations during dispersion.Typical Specifications
Grade: Industrial
Appearance: White or off-white powder
Solid Content: ≥98%
Application Method
Add 1–5% of the total formulation amount of the matting agent (with a matting agent-to-TGIC ratio of 20:1) and mix uniformly with other raw materials before extrusion. Follow standard powder production processes. The exact dosage can be determined through testing.Product Features
-Suitable for polyester/TGIC powder coatings with a gloss level of 8 or above (60°).
-Excellent performance with minimal usage, offering outstanding cost-effectiveness.
-Coating surface is exceptionally smooth, with superior yellowing resistance and mechanical properties.
Packaging Details
Polyethylene inner bag with kraft paper outer packaging. Net weight: 25 kg per bag.Storage Requirements
Store in a cool, dry, well-ventilated place, sealed. Avoid direct sunlight, high temperatures, high humidity, and keep away from fire and heat sources to prevent caking. Storage temperature should be below 30°C. Shelf life: 12 months. If the storage period is exceeded, the product may be retested; if results meet specifications, it can still be used.Kindly Reminder
1.Strengthen the control of the powder production process: increase extrusion feeding speed, lower extrusion temperature, and ensure stable matting effect.
2. The type and dosage of fillers and polyesters from different suppliers affect gloss, so the matting agent requires proper compatibility with other formulation components.
3. Appropriate addition of curing promoters can improve impact strength but may lead to increased gloss or poor leveling performance.
4. Increasing the dosage of matting agent raises reactivity, shortens curing time, and reduces gloss, which may affect storage stability. Different polyester grades vary in reactivity, so users should adjust based on actual conditions, paying attention to powder storage stability. Please conduct testing before batch production.
5. The matting agent may deliver unexpected benefits. However, due to varying powder application conditions.
