This article systematically introduces the concept, characteristics, functions, application fields, selection considerations, and solutions to common problems of elevator powder coating. It focuses on the applications of elevator powder coating to help everyone better understand what elevator powder coating is, as well as its characteristics and functions.

What Is Elevator Powder Coating

Elevator powder coating is an environmentally friendly thermosetting powder coating specially designed for the elevator industry. It is mainly applied to the surfaces of metal components such as elevator door panels, elevator cabins, control panels, escalator accessories, and other parts through electrostatic spraying processes.

Characteristics of Elevator Powder Coating

The main characteristics of elevator powder coating are as follows:

1. Green, Environmentally Friendly, Safe and Efficient

Powder coatings basically contain no VOCs (volatile organic compounds), solving the problem of exhaust emissions at the source.

At the same time, overspray powder can be recycled and reused. Compared with traditional paint coatings, the overall cost can be reduced by approximately 20%, and production efficiency can be improved by 30%–40%.

2. Excellent Physical Properties and Long-Term Durability

Elevator components are frequently used and require high coating durability.

This type of coating can form a coating with high hardness (≥H), strong adhesion (Class 0), and high impact resistance (≥50kg·cm). It provides excellent wear resistance, scratch resistance, and corrosion resistance, allowing it to withstand frequent use and daily wear.

Some coatings specially designed for elevator steps can achieve weather resistance levels above 1200 hours and scratch resistance up to 3H.

3. Combination of Decoration and Functionality

(1) Strong Decorative Performance

It can provide rich colors, gloss levels, and various texture effects such as smooth finish, orange peel texture, and sand texture, meeting aesthetic design requirements for elevators in different environments.

Some products also feature fingerprint resistance and easy-cleaning properties, helping maintain a clean and attractive appearance.

(2) Development of Specialized Functions

For specific components, special functions can be achieved through formulation design.

For example, anti-slip powder coatings use phenolic epoxy systems combined with orange peel textures to provide excellent anti-slip performance for elevator safety components.

Functions of Elevator Powder Coating

The main functions of elevator powder coating are reflected in the following aspects:

1. Long-Term Physical Protection

It forms a durable protective layer on elevator metal components, providing excellent scratch resistance, impact resistance, wear resistance, and corrosion resistance.

It effectively resists daily impacts, scratches, and cleaning agent corrosion caused by frequent use, significantly extending the service life of elevator door panels, cabins, control panels, and other components.

2. Decorative and Beautification Function

It provides rich colors, gloss levels, and textures (such as sand texture, orange peel texture, and metallic effects), meeting the requirements of different architectural styles and elevator interior designs.

Functional decoration such as floor guidance and safety warning markings can also be achieved through specific colors and identification coatings.

3. Other Special Functions

According to specific elevator application requirements, specialized functions can be developed:

(1) Anti-Slip Function

Through orange peel textures or special texture designs, it is used for elevator steps or entrance platforms to improve safety performance.

(2) Fingerprint Resistance / Easy Cleaning

It keeps elevator control panels and cabin walls clean and smooth, reducing daily cleaning and maintenance difficulties.

For outdoor sightseeing elevators or semi-outdoor escalators, weather-resistant powder coatings can be selected to withstand sunlight and rain exposure.

Where Is Powder Coating Used in Elevators

The elevator components using powder coatings mainly include the following:

1. Door System

Widely used for elevator door panels, door frames, door covers, landing doors, and other components.

The coating needs excellent scratch resistance and impact resistance to withstand frequent opening and closing operations and accidental impacts during waiting periods.

2. Elevator Cabin System

Used for cabin wall panels, ceilings, cabin floors, handrails, control panel surfaces, and other components.

These areas focus most on decorative effects and tactile feel, providing various colors and texture options (such as sand texture and antibacterial coatings) to create a comfortable elevator environment.

3. Escalator Components

Used for escalator steps, skirt panels, inner and outer covers, handrail guides, and other components.

Anti-slip powder coating is a typical application for escalator steps. Through orange peel textures or special textures, it provides necessary anti-slip safety protection.

4. Other Accessories

Including counterweights, buffers, guide rail brackets, cable channels, and other internal structural components.

These parts focus more on corrosion protection and protective performance to ensure long-term stable elevator operation.

How to Choose Elevator Powder Coating

When selecting elevator powder coating, we often face difficulties in choosing the right product. Based on our industry experience, we recommend focusing on the following aspects:

1. Determine Functional Requirements According to Components

Different elevator components have completely different performance requirements.

(1) How to Select Powder Coating for Elevator Cabin Walls and Door Panels

Appearance and tactile feel are the most important factors.

Fine sand texture, orange peel texture, or smooth high-gloss products are preferred. Colors and gloss levels should be selected according to design requirements.

For premium appearance, metallic powder or fingerprint-resistant coatings can be selected.

(2) How to Select Powder Coating for Elevator Handrails and Control Panels

These areas are frequently touched and require scratch resistance, fingerprint resistance, and easy cleaning.

High-hardness (≥2H) fine sand texture or special fingerprint-resistant powder coatings are recommended, providing both texture and stain resistance.

(3) How to Select Powder Coating for Elevator Steps (Escalator Platforms)

Anti-slip performance is the first priority.

Orange peel anti-slip powder coatings must be selected. The texture provides friction, while the coating must also have high wear resistance and weather resistance (suitable for semi-outdoor/outdoor sightseeing elevators).

(4) How to Select Powder Coating for Internal Structural Components (Guide Rails, Brackets, Counterweights)

Focus on corrosion protection and adhesion rather than appearance.

Standard epoxy/polyester hybrid powder coatings or pure epoxy powder coatings can be selected. They offer controlled costs while meeting long-term protection requirements.

2. Determine Weather Resistance Grade According to Environment

Select products with appropriate weather resistance according to elevator installation location.

(1) Indoor Elevators

Conventional epoxy/polyester hybrid systems or polyester/HAA systems are sufficient, offering good cost performance and adequate protection.

(2) Outdoor Sightseeing Elevators / Semi-Outdoor Escalators

Polyester/TGIC or polyurethane (PU) super weather-resistant systems must be selected to ensure long-term resistance to ultraviolet radiation and prevent fading and chalking.

(3) Coastal High Salt Spray / Industrial Pollution Areas

In addition to weather resistance, high salt spray resistance (≥500h) is required. Reinforced anti-corrosion formulations or fluorocarbon powder coatings (PVDF) should be selected.

3. Select Texture and Color According to Decoration Requirements

Texture Selection:

(1) Sand Texture

Provides excellent hiding ability, dirt resistance, and wear resistance. It is suitable for door panels, cabin walls, handrails, and other areas, making it the most commonly used elevator texture.

(2) Orange Peel Texture

Provides good anti-slip performance and is suitable for elevator steps. It can also be used for decorative panels to create a unique texture effect.

(3) Smooth Finish (High Gloss / Matte)

Provides a clean and bright appearance, suitable for high-end elevator cabins, but requires higher substrate surface quality.

Color Selection:

(1) Dark Colors (Red, Dark Blue, etc.)

Ceramic pigments should be selected to ensure outdoor color retention.

(2) Light Colors / White

Attention should be paid to yellowing resistance.

4. Consider Compliance and Confirm Safety and Standards

Elevators are special equipment and have strict fire safety requirements.

(1) Fire Rating

For elevator doors and cabin powder coatings, compliance with GB 8624 classification requirements for combustion performance of building materials and products should be confirmed (usually requiring B1 grade or above).

(2) Environmental and Hygiene Requirements

For medical elevators or food-related applications, attention should be paid to low VOC requirements, antibacterial properties, and absence of heavy metals (such as lead and chromium).

(3) Industry Standards

Relevant group standards such as “T/CEAC 118-2025 Powder Coatings for Elevators” can be referenced as a basis for product selection.

Common Problems and Solutions of Elevator Powder Coating

The most common problems during the use of elevator powder coating are mainly reflected in the following aspects. Based on our industry experience, we provide corresponding solutions to help effectively solve powder coating problems encountered during application.

1. Coating Peeling and Detachment Problems

Problem Description:

The coating peels off in sheets during cross-cut testing or falls off after impact.

Main Causes:

Incomplete substrate pre-treatment (oil contamination and oxide scale not fully removed); poor phosphating/silanization film quality; insufficient curing.

Solutions:

Strictly follow pre-treatment procedures (degreasing → washing → passivation → drying); inspect conversion coating quality (phosphating film weight 1.5–3.0g/m²); confirm curing temperature and time meet requirements (such as 200℃ × 10–15min), and perform oven temperature tracking tests.

2. Coating Easily Scratched

Problem Description:

Frequently touched areas such as elevator door panels and control panels are easily scratched by fingernails or sharp objects.

Main Causes:

Insufficient coating hardness (improper resin system or curing agent ratio); incomplete curing.

Solutions:

Use high-hardness resin systems for elevator decorative surfaces (hardness ≥2H); confirm curing parameters to ensure sufficient cross-linking density; appropriately add wear-resistant additives (such as micronized wax).

3. Outdoor Fading and Chalking Problems

Problem Description:

After several months of use in sightseeing elevators or outdoor escalators, colors become significantly lighter and white powder appears on the surface.

Main Causes:

Incorrect product selection—indoor powder coatings were used in outdoor environments; or pigments/resins in the formulation are not UV-resistant.

Solutions:

Outdoor applications must use polyester/TGIC or polyurethane super weather-resistant systems; dark colors should use ceramic pigments or coated inorganic pigments; suppliers should provide QUV aging test reports (≥1000h).

4. Surface Particle and Impurity Problems

Problem Description:

Visible particle-like foreign matter appears on the coating surface.

Main Causes:

Unclean spraying environment; powder moisture absorption and clumping; recycled powder not screened; impurities falling from curing oven.

Solutions:

Keep spray booths and curing ovens clean; store powder under moisture-proof conditions (≤25℃, humidity ≤60%); screen recycled powder through 100–150 mesh before use.

5. Excessive Orange Peel or Poor Leveling Problems

Problem Description:

The coating surface shows obvious orange peel texture, uneven gloss, and rough tactile feel.

Main Causes:

Powder particle size is too large (D50 >45μm); curing temperature rises too quickly, resulting in insufficient melting and leveling time; spraying film thickness is too thin (<60μm).

Solutions:

Control powder particle size D50 at 35–45μm; adjust curing oven heating curve (heating rate ≤15℃/min); ensure coating thickness ≥60μm.
