Key Characteristics & Performance
Resin Base: Indoor Matting Agent HM3328 is synthesized from tailor-made polymer resins rather than relying on traditional chemical reactions.
Gloss Reduction: Indoor Matting Agent HM3328 can efficiently achieve gloss levels as low as 6%.
Anti-Yellowing: Compared to reactive matting agents, Indoor Matting Agent HM3328 provides excellent heat stability and anti-yellowing properties.
Surface Leveling: Indoor Matting Agent HM3328 improves the flow and leveling of the powder coating, resulting in a finer, higher-quality finish.

Labeling Claims: Wax-free
Features: Good Leveling, Good Mechanical Properties, Matting, Yellowing Resistance
Key Technical Features
Deep Matte Capability: While HM3327 spans a wider mid-to-low gloss range, Indoor Matting Agent HM3328 is the preferred choice when formulators need to reach extreme matte profiles—capable of achieving a gloss level as low as 5% to 6% (measured at a 60° angle).
Superior Leveling & Fine Appearance: Traditional chemical-reaction matting agents (like cyclic-amidine salts) create a matte surface via non-uniform shrinkage, which often leads to a rough, micro-textured, or orange-peel finish.
HM3328 relies on physical polymer incompatibility to scatter light, providing an exceptionally smooth, uniform, and fine visual appearance.
Outstanding Yellowing Resistance: Indoor Matting Agent HM3328 exhibits excellent thermal stability during high-temperature baking.
Indoor Matting Agent HM3328 prevents initial yellowing or overbake-induced discoloration, making Indoor Matting Agent HM3328 highly reliable for pure white and light pastel shades.
Preserved Mechanical Integrity: Indoor Matting Agent HM3328 limits gloss effectively without severely degrading the film’s physical durability.
Cured films maintain robust flexibility, strong adhesion, and excellent 50 cm impact resistance.
Typical Applications
Indoor Matting Agent HM3328 is primarily utilized in indoor powder coatings where a low film gloss and a high-quality haptic or aesthetic appearance are required.
Key Features & Application
Compatible Resin Systems: Formulated primarily for Epoxy/Polyester (Hybrid) indoor powder coating systems.
Matting Efficiency: Capable of reducing the gloss level of coatings down to as low as 6%.
Mechanism: It operates through physical matting (creating micro-roughness on the film surface) rather than chemical reactions, ensuring stable gloss control.
Film Quality: Maintains excellent leveling, flow properties, and storage stability of the powder coating without compromising impact resistance.
