How to Choose the Right Polyurea Spray Equipment

Polyurea spray systems consist of two highly reactive components that undergo rapid chemical reaction within seconds after mixing, causing viscosity to rise sharply. Without proper equipment for transferring, metering, mixing, atomizing and cleaning, this reaction cannot be effectively controlled. Therefore, polyurea application must rely on dedicated high-temperature, high-pressure spray equipment — a process fundamentally different from traditional paint application. In other words, spray equipment is the core foundation of polyurea application and a key factor in ensuring coating quality.

Below, we will guide you through the major equipment types and brand options to help you select the most suitable polyurea spray machine for your project.

1. Types of Polyurea Spray Equipment

Currently, polyurea spray machines on the market are mainly categorized into pneumatic, electric, and hydraulic systems.

1. Pneumatic Spray Machines

Pneumatic machines are driven by compressed air. Their biggest advantages are affordability, simple structure, and easy maintenance, making them suitable for teams with limited budgets or small-scale projects. However, due to the compressibility of air, pressure fluctuations may occur during operation, leading to less uniform atomization and lower stability compared with electric or hydraulic machines. They are ideal for applications with modest stability requirements and low-cost investment goals.

2. Electric Spray Machines

Electric spray machines are the most widely used in the polyurea industry. Powered by an electric motor, they deliver more stable pressure output than pneumatic systems, making them suitable for most standard polyurea applications. However, electric machines are more sensitive to circuit board quality and on-site voltage stability. Voltage fluctuations may cause damage to the control board. They are best suited for regions with stable electrical supply and can meet the needs of most projects.

3. Hydraulic Spray Machines

Hydraulic machines utilize a hydraulic system to drive the pump, providing highly stable and high pressure output. Even during large-area, long-duration, high-intensity spraying, they maintain excellent performance. Their main drawback is higher equipment cost, making them more suitable for professional contractors or large-scale engineering projects.

2. Recommended Equipment Options

Polyurea spray equipment generally falls into two categories: high-end imported systems and cost-effectivedomestic machines. Below are our selection suggestions based on budget and application needs.

Imported High-End Equipment

Graco polyurea spray systems from the United States hold a significant market share. Models such as HXP-3 and EXP-2 have demonstrated excellent stability in demanding working environments and are widely used by professional contractors.

Key advantages include:

• Outstanding pressure and ratio stability

• Strong heating capacity

• Low failure rate during long-term operation

• Reliable performance in high-intensity, continuous spraying tasks

If your budget allows, or if imported equipment pricing is acceptable in your region, Graco remains our top recommendation.

Cost-Effective Domestic Options

With the growing adoption of polyurea technology in China, domestic spray equipment has improved rapidly. Domestic machines now offer strong advantages in price, maintenance cost, and spare parts availability. For users aiming to control investment while maintaining stable performance, domestic equipment is often the most cost-effective solution.

Among them, our company’s JHSW-E2 high-pressure polyurea spray machine is designed specifically for polyurea and polyurethane engineering applications. The system is electrically driven and equipped with an intelligent interaction platform and modular structure, enabling quick component maintenance and process switching. It adapts flexibly to various coating tasks. The machine is paired with a domestic spray gun similar to the Graco Fusion AP, providing stable overall spray performance.
