China Polyurethane Anti-Slip Paint Suppliers | Durable Coating from a Reliable Factory
Product Features
-
High anti-slip performance, with controllable surface roughness (typically with a dry friction coefficient ≥0.6 and a wet friction coefficient ≥0.4), effectively preventing slipping of personnel or vehicles
-
Excellent durability — the polyurethane system endows the coating with high wear resistance, impact resistance, and good flexibility, making it suitable for high-traffic or heavy-load areas
-
Strong weather resistance (aliphatic type) — if aliphatic isocyanate (such as HDI) is used, it can be used outdoors for a long time without yellowing or losing its gloss, making it suitable for exposed areas such as decks and platforms
-
Resistant to chemical corrosion, oil, water, weak acids and alkalis, and salt spray — suitable for harsh environments such as marine and industrial settings
-
Strong adhesion — good adhesion to steel, concrete, old coatings, and other substrates
-
Customizable texture and color — aggregate size (coarse/medium/fine) and color (gray, green, red, yellow, etc.) can be adjusted according to needs, balancing safety and aesthetics
Recommended Use
Used as anti-slip finish for facilities with high decorative requirements, such as bridges, ships, aprons, offshore platforms, decks, and stairs.

Application
Construction Method
Airless spraying
Nozzle pressure: 14 MPa – 21 MPa
Nozzle hole diameter: 0.6 mm – 0.8 mm
Surface Treatment and Construction Conditions
To avoid condensation, work on a clean, dry surface at least 3°C [5°F] above the dew point.
The primer surface should be dry and free from any contaminants (oil, grease, salt, water, dust, etc.) and overcoated within the specified overcoating intervals.
Relative humidity must be less than 85% during application and curing.

Frequently Asked Questions (FAQ)
Q
What friction coefficients does this anti-slip polyurethane coating provide?
This coating delivers a dry friction coefficient of ≥0.6 and a wet friction coefficient of ≥0.4, ensuring reliable anti-slip performance for both personnel and vehicles under various surface conditions.
Q
Is this coating suitable for outdoor and marine environments?
Yes. When formulated with aliphatic isocyanate (such as HDI), the coating offers excellent UV resistance and will not yellow or lose gloss over time, making it ideal for exposed outdoor areas, decks, offshore platforms, and marine environments. It also resists oil, salt spray, and weak acids and alkalis.
Q
What substrates can this polyurethane anti-slip coating adhere to?
The coating exhibits strong adhesion to a wide range of substrates, including steel, concrete, and existing old coatings, making it versatile for new construction as well as maintenance and refurbishment projects.
Q
How long does this coating take to dry and what are the recoating intervals?
At 20°C, the coating is dry to touch within 1.5 hours and fully dry within 9 hours. The minimum recoating interval at 20°C is 10 hours. Drying and curing times vary with temperature — lower temperatures require longer waiting periods.
Q
Can the color and texture of the anti-slip coating be customized?
Yes. The aggregate size (coarse, medium, or fine) and color (including gray, green, red, yellow, and more) can both be adjusted to meet specific project requirements, allowing a balance between functional safety and visual aesthetics.
Q
What are the recommended application conditions for this coating?
The coating should be applied using airless spraying (nozzle pressure 14–21 MPa, nozzle diameter 0.6–0.8 mm) on a clean, dry surface at least 3°C above the dew point. Relative humidity must remain below 85% throughout application and curing. The surface must be free of oil, grease, salt, water, and dust before application.
