Continuous coating machine YG series

high-performancepneumaticheavy-duty

Overview
A polyurea coating machine is a high-pressure, two-component spray system engineered for industrial waterproofing, anticorrosion and wear-resistant coatings. It accurately meters and mixes A/B components under high pressure for near-instant curing and continuous application, suitable for large-scale infrastructure and industrial projects.

Key Advantages

• Rapid curing: coatings cure in seconds to accelerate project schedules.
• High-pressure stability: engineered to reduce pressure fluctuation and ensure uniform film thickness.
• Chemical and mechanical resistance: formulated coatings provide long-term protection in demanding environments.

Hydraulic Driven Polyurea Machines (e.g., YG-H5600)
Hydraulic drive units deliver high power and stable output for continuous, heavy-duty operation on large projects.

• Pressure capability: maximum single-sided pressure up to 36 MPa in standard configurations.
• Operational stability: minimal pressure drop for consistent coating thickness.
• Continuous operation: designed for extended runtimes in harsh conditions.

Pneumatic Booster Polyurea Machines (e.g., YG-Q30)
Pneumatic booster systems are suited to entry-level or medium-scale jobs where portability and simpler maintenance are priorities.

• Simple maintenance: mechanical design allows easier on-site repair.
• Lower initial cost: cost-effective option for medium budgets.
• Core components: pneumatic cylinders and booster design maintain consistent power output when paired with a suitable compressor.

Materials & Compatibility
Designed primarily for polyurea materials and often compatible with polyurethane systems. Select models support upgrades for multifunction spraying (polyurea and PU foam). Typical reference mixing ratio for polyurea systems is 1:1; confirm specific resin requirements per project.

Diverse Application Scenarios
Infrastructure waterproofing and anticorrosion
Applied on bridges, tunnels and other civil structures requiring crack accommodation, tensile strength and long-term sealing.

Industrial flooring and mining equipment
Used on workshop floors and mineral processing equipment for superior impact and abrasion resistance compared with standard coatings.

Water parks and landscape design
Commonly used for pools, water attractions and thematic foam structures where rapid curing and waterproofing are required.

Case Study
Client: contractor in Brazil required corrosion-resistant lining for three large sewage tanks. Solution: YG-H5600 hydraulic unit with 22 kW heating and a 1:1 mix. Result: strong chemical resistance and project time reduced from an estimated 20 days to 12 days.

FAQ Highlights

• Not all PU spray machines can apply polyurea; polyurea systems typically require higher pressure and specialized components.
• Some polyurea machines can spray foam if configured accordingly; verify model compatibility before use.
• Clogging prevention: multi-stage filtration and self-cleaning spray guns reduce maintenance downtime.
• Operational temperature range: -10°C to 50°C for typical models.
• Portable models: units approximately 80–120 kg for small projects and easy transport.
