PU Spray Applications
From building insulation to chemical-resistant tank linings, polyurethane and polyurea spray systems power some of the most demanding industrial applications. Below: five primary use cases, the JYYJ machine series we recommend for each, and project case studies from real customers.
By Industry
Each industry vertical has its own pressure, hose-length, and chemistry requirements. Our machine lineup spans all three.
Construction & Insulation
Building envelope, roofing, attic, wall, cold storage. Continuous closed-cell PU foam delivers R-6.5 to R-7 per inch with full air-sealing in a single application.
Industrial Coatings
Tank linings, secondary containment, chemical-resistant flooring, marine and offshore. Polyurea and high-density PU systems handle aggressive chemistries and thermal cycling.
Cold Chain & Refrigeration
Cold storage panels, freezer rooms, vaccine logistics. -40°C service temperature with closed-cell stability and food-contact compliance paths.
All Applications

Spray Foam Insulation
High-performance thermal insulation for walls, roofs, attics, and industrial buildings. Seamless, air-tight, energy-efficient.
Polyurea Waterproofing
Fast-curing 100% solids polyurea coating for roofs, terraces, pools, and containment. Seamless waterproof membrane with extreme elongation and tear strength.
Cold Storage Insulation
High-density closed-cell PU foam for walk-in freezers, cold chain warehouses, and food processing facilities operating at -25°C to -40°C.
Spray Foam Roofing
Seamless spray polyurethane roof systems for commercial flat roofs and metal roof retrofits. Self-flashing, reflective topcoat compatible.
Polyurea Tank Lining
Polyurea linings for petroleum, chemical, and water storage tanks. Chemical-resistant, seamless, corrosion protection.
