Major Application: Indoor Powder Coatings, specifically formulated for Epoxy/Polyester (Hybrid) resin systems.
Labeling Claims: Wax-free.
Formulation Details
Target Systems: Exclusively optimized for indoor Epoxy/Polyester (Hybrid) powder coating systems.
End Uses: Commonly applied to indoor metal furniture, household appliances, control panels, and decorative fixtures.
Processing: Because Indoor Matting Agent HM3327 is a physical polymer flattener,Indoor Matting Agent HM3327 is incorporated directly into the premix zone and extruded alongside the resins, pigments, and fillers.
Chemical Identity & Mechanism
Chemical Family: Acrylate resin-based polymeric blend.
Classification: Physical/polymeric matting agent (non-reactive).
Mechanism: Indoor Matting Agent HM3327 creates a controlled, non-uniform microscopic roughness on the cured paint film.
This microstructure scatters incoming light rays in multiple directions instead of reflecting them cleanly, which lowers the observed gloss.

Advantages over Chemical-Reaction Matting Agents
Traditional chemical matting agents rely on competing reaction speeds between different resins, which can be hard to control and often results in a rough surface or safe-zone limitations. Because Indoor Matting Agent HM3327 is an acrylate-based matting agent, Indoor Matting Agent HM3327 achieves a lower gloss while maintaining a highly aesthetic, smooth-to-the-touch surface structure.
Key Performance Benefits
Wide Gloss Range: Formulators can adjust the dosage to hit any specific gloss level between 5% and 70% (from dead-matte to semi-gloss finishes).
Anti-Yellowing: Unlike traditional chemical reaction matting agents, HM3327 has excellent thermal stability and color retention under high baking temperatures.
Surface Quality: Indoor Matting Agent HM3327 delivers superior leveling and flow properties, resulting in a highly uniform, fine surface appearance free of "orange peel" textures.
Mechanical Strength: Indoor Matting Agent HM3327 maintains the coating's original scratch resistance, impact flexibility, and adhesion properties without making the film brittle.
Key Technical Features
Wide Gloss Range: Indoor Matting Agent HM3327 can help formulators achieve a variety of finishes, ranging from low-gloss dead matte to semi-gloss (5% to 70% gloss levels at a 60° angle).
Superior Levelling: Unlike traditional physical or high-reaction chemical matting agents that can leave a textured or orange-peel finish, Indoor Matting Agent HM3327 provides exceptional flow and leveling.
This results in a very fine, uniform, and smooth surface appearance.
Anti-Yellowing (Yellowing Resistance): Indoor Matting Agent HM3327 features excellent thermal stability and resistance to yellowing during the high-temperature baking/curing process, making Indoor Matting Agent HM3327 safer for white or light-colored coatings.
Preserved Mechanical Properties: Indoor Matting Agent HM3327 reduces gloss without severely degrading the impact resistance, flexibility, or adhesion of the cured film.
The core function of matting agent is to adjust the surface gloss to achieve the desired matte, semi-matte or soft light effect.
The following are its main uses:
Improve visual beauty: In the fields of furniture, automobiles, walls, etc., too high gloss may appear glaring or cheap, and matte treatment is more textured and advanced.
Improve the fineness of the feel: Especially in plastics, leather, and coatings, adding matting agents can make the surface softer and more delicate.
Enhance scratch resistance: Some matting agents can increase surface hardness and abrasion resistance, making the product more durable.
Reduce light pollution: In specific places such as exhibition halls and theaters, matte surfaces help prevent light interference and improve space comfort.
Adjust product personalization style: The same product can present different textures after using different matting agents, which improves market diversity.
Storage & Safety
Store in a cool, dry place at temperatures below 30°C to avoid caking.Keep the bags tightly sealed when not in use as the material can be slightly hygroscopic.
Under proper storage conditions, the shelf life is at least 1 year from the date of manufacture.
