A polyurethane spray machine is an advanced industrial tool designed for the precise and efficient spraying of polyurethane foam or coatings. Known for its excellent insulation, waterproofing, and protective properties, polyurethane is widely used in construction, infrastructure maintenance, and manufacturing industries. This machine is especially beneficial for applications requiring uniform spraying, fast curing, and minimal material waste. With its high-pressure spraying system and intelligent temperature control, the machine ensures a smooth, fine spray suitable for diverse environments.
Whether you’re insulating a cold storage room, protecting pipelines from corrosion, or waterproofing basements and rooftops, this equipment offers unparalleled efficiency and convenience. Contact us to know more details now!【WhatsApp/WeChat/Phone/Skype】+86 13837115193.

Working Principle of the Polyurea Coating Machine
The operation starts with lifting pumps that draw raw materials (components A and B) from their containers. These materials are delivered through the feed hoses into the main unit, where the metering pump ensures an accurate mix ratio. Once heated and pressurized, the components move through the insulated hose to the spray gun. Inside the spray gun’s mixing chamber, the materials mix forcefully under high pressure. Upon triggering, the spray gun sprays the mixed solution as a fine mist onto the target surface. The addition of compressed air at the nozzle ensures a uniform spray pattern, maximizing adhesion and coverage.
Key Advantages of Using Polyurethane Spraying Equipment
- Fast Application: High-speed spraying saves time on large projects.
- Precise Mixing: Accurate ratio control ensures consistent quality.
- Thermal Stability: Powerful heating system allows usage in cold climates.
- Lightweight & Mobile: Compact design for easy transport and setup.
- Safety Features: Multi-level leakage protection, emergency stop systems, and digital monitoring enhance user safety.
- Wide Viscosity Range: Handles materials with viscosity between 200–1000 CPS.
These benefits result in lower labor costs, reduced material waste, and improved project outcomes, making it an ideal choice for contractors and industrial users.
Applications of Polyurethane Spray Machines Across Industries
- Building Insulation: Exterior walls, basements, attics, and roofs.
- Cold Chain Solutions: Freezers, cold storage units, and refrigerated vehicles.
- Waterproofing: Tanks, pools, tunnels, and embankments.
- Industrial Coatings: Pipelines, steel structures, and protective linings.
- Infrastructure Maintenance: Bridge decks, concrete protection, and corrosion resistance.
Additionally, when equipped with special components, this system can also serve as a polyurea coating machine, expanding its usability to demanding waterproofing and anti-corrosion applications.
