Matte powder coatings refer to a category of powder coatings whose cured film exhibits a relatively low surface gloss. They provide a soft, diffuse reflection visual effect.

This article systematically introduces the types, effect realization, functions, applications, and development trends of matte powder coatings, with a focus on their unique performance characteristics. The aim is to help readers better understand the specific value of matte powder coatings within the powder coating product system.

Types of Matte Powder Coatings

Based on gloss level, matte powder coatings can be classified as follows:

Semi-matte Powder Coatings:

Gloss typically ranges from 30–50%. The surface is soft yet retains some reflection, offering a balanced look that is more visually enduring than high-gloss coatings.

Matte Powder Coatings:

Gloss typically ranges from 10–30%. Surface reflection is weak, providing a silky or parchment-like fine texture.

Ultra-matte/Full-matte Powder Coatings:

Gloss typically ranges from 5–10% or lower. The surface is almost non-reflective, achieving an extreme matte effect that visually resembles a “blackboard” or “velvet-like” appearance.

How Matte Powder Coatings Are Achieved

The core principle of matte powder coatings is to disrupt the smoothness of the film surface, causing diffuse reflection rather than the mirror-like reflection of high-gloss coatings. This is mainly achieved through the following methods:

1. Physical Matting

This is the most common and cost-effective method. It works by adding small particles incompatible with the resin matrix into the powder coating. During curing, these particles migrate to the surface, creating micro-roughness.

Inorganic matting agents: ultrafine silica, matting barium, talc.

Organic matting agents: micro-powdered wax.

Fillers: calcium carbonate, barium sulfate.

2. Chemical Matting: Resin System Reaction Differences

By formulating resins with mismatched reaction rates, micro-phase separation structures spontaneously form during curing, producing a rough surface.

Dry blending method: Physically mix two powders with vastly different curing speeds in a specific proportion.

Single-component addition method: Directly incorporate a specially designed matting resin into the powder formulation.

3. Physical Form Control

Altering the physical state of the powder particles to influence final gloss.

Mechanical pulverization: Ball-mill cured high-gloss powder coatings to obtain irregular, angular particles.

Dry-mixed pigments/fillers: Pre-fine-mill pigments or fillers and dry-mix them into the base powder.

Functions of Matte Powder Coatings

Matte powder coatings primarily impart a soft, low-gloss visual effect to workpiece surfaces. Specific functions include:

Creating Soft, High-end Visual Effects

Reducing visual glare: Diffuse reflection softens light and reduces eye strain.

Elegant and premium appearance: Matte surfaces naturally convey subtle, understated, and sophisticated aesthetics.

Rich texture options: Surfaces can present velvet, sand, or frosted effects.

Defect Concealment

The diffuse reflection of matte surfaces scatters light, making surface defects less noticeable and reducing strict requirements for substrate smoothness. Scratches are visually less apparent compared to high-gloss coatings, providing superior apparent scratch resistance.

Fingerprint Resistance and Ease of Cleaning

Matte surfaces have very low specular reflection, making fingerprints less visible. They attract less dust, and dirt can be easily wiped off due to the smooth surface.

Unique Tactile and Functional Properties

Comfortable touch: Ultra-matte velvet or frosted coatings can mimic the delicate, warm, soft feel of baby skin, sheepskin, or silk, greatly enhancing user experience.

Anti-slip: Sand-textured or wrinkled matte surfaces provide micro-roughness that improves slip resistance.

Anti-glare: Ultra-matte coatings can effectively reduce glare, protecting the user’s eyesight.

Applications of Matte Powder Coatings

According to their functions, matte powder coatings are mainly applied in:

Consumer Electronics and High-end Appliances

This is one of the fastest-growing and most technically demanding application areas.

Widely used in laptops, tablet housings, smartphone backs, headphones, smartwatches, high-end audio panels, projectors, and appliance panels.

Office and Residential Furniture

Furniture requires soft aesthetics and wear resistance.

Applied in office desks, chairs, filing cabinets, partitions, residential metal furniture, public seating, and benches.

Transportation and Industrial Equipment

This sector leverages matte coatings for anti-glare, weather resistance, and scratch resistance.

Used in automotive interior and exterior components, motorcycles, bicycle frames, industrial machinery, equipment housings, toolboxes, and storage racks.

Construction and Decorative Materials

Traditional market for matte powder coatings requiring long-term outdoor durability and low light pollution.

Applied in aluminum doors, windows, curtain walls, railings, fences, gates, interior trim, baseboards, and lighting housings.

Additionally, matte coatings are widely used in medical equipment housings, optical instruments, and measurement tools.

Development Trends of Matte Powder Coatings

The technical development trends of matte powder coatings include:

Surface Texture Evolution

Matte is no longer merely low gloss but increasingly linked with premium tactile experience.

Skin-feel technology: By optimizing the ratio of resin, curing agent, and matting system, “low-gloss skin” powder coatings can be produced, transforming the “cold, hard” impression of metal coatings into a warm, delicate tactile feel.

Material Innovation

Traditional physical matting often compromises leveling and mechanical performance.

Chemical self-matting without matting agents: Designing a dual-component “high/low activity” resin system allows micro-rough structures to form spontaneously during curing.

This technology overcomes the traditional trade-off between matting and mechanical performance, maintaining excellent flexibility and impact resistance even after low-temperature curing and long-term storage.

Process Advancement

Mature low-temperature indoor matting technology: Indoor low-temperature matting for flat panels is maturing, enabling commercial applications in heat-sensitive furniture panels and appliances.

Precise formulation control: In epoxy-dicyandiamide systems, catalyst levels can be precisely controlled at 0.5–1.0% to balance matting and leveling, while low-epoxy equivalent resins improve mechanical performance under low-temperature curing.

Core Application Value of Matte Powder Coatings

Matte powder coatings provide soft, defect-concealing surfaces that visually hide scratches and fingerprints while delivering a comfortable tactile experience. This significantly enhances the product’s aesthetic and functional durability, making matte coatings highly versatile for future applications.
