Industrial-Grade Aliphatic Vehicular Traffic Coating
(High-Durometer & Heavy-Duty Loading Specification)
Product Overview
The definitive surfacing solution for environments subject to extreme mechanical abrasion and heavy vehicular movement. This single-component, moisture-curing aliphatic polyurethane system is engineered with an ultra-high-modulus matrix to deliver exceptional surface hardness and structural toughness. Specifically designed for parking structures and transit hubs, it creates a seamless, high-density armor that withstands the aggressive shear forces of turning tires while providing permanent UV stability and chemical defense.
Core Advantages
▪ Elite Tire-Scrub & Shear Resistance: Formulated with high-durometer polymer technology to provide an exceptionally hard wear surface. It is specifically engineered to resist the mechanical “rubbing” and shear
stress of heavy vehicular traffic, preventing delamination and surface wear in critical zones like ramps,
turning circles, and loading bays.
▪ Structural Anti-Corrosion Shield: Acts as a high-density barrier against de-icing salts, chlorides, and
automotive fluids. By preventing chemical ingress into the concrete matrix, the system safeguards reinforcement steel from internal oxidation, significantly extending the service life of multi-story parking assets.
▪ Permanent Aliphatic Gloss & UV Stability: Unlike aromatic alternatives, this 100% aliphatic chemistry
rovides a stable, non-yellowing finish that will not chalk or embrittle under direct solar exposure. It ensures long-term aesthetic clarity and structural integrity for exposed top-decks and open-air stadium ramps.
▪ Dynamic Load Accommodation: Despite its extreme hardness, the membrane retains sufficient
elastomeric flexibility to bridge structural micro-cracks. It flawlessly accommodates the thermal expansion
and vibrational stresses inherent in large-scale concrete parking assemblies.
Engineered Applications
▪ Heavy-duty vehicular traffic decks and multi-story parking structures.
▪ High-stress transition zones: ramps, helixes, and entrance/exit bays.
▪ Industrial loading docks and commercial transit hubs.
▪ Civil infrastructure projects requiring high-abrasion resistance and UV stability.
System Integration: The Heavy-Duty Vehicular Armor Matrix
To guarantee the survival of a multi-story parking structure under the brutal shear forces of turning tires, braking vehicles, and relentless thermal cycling, a surface coating is insufficient. Vehicular traffic decks are the most unforgiving environments in commercial construction. Eliminate catastrophic tire-scrub delamination, optimize your per-square-meter deployment costs, and defend the structural rebar by integrating these mandatory sub-grade components:
Capital-Optimized Waterproofing Base Core:
Must pair with: Concealed Elastomeric PU System
Why it’s critical: Specifying a premium aliphatic topcoat for the full multi-millimeter build of a parking deck will destroy your project budget. The global engineering standard for vehicular decks requires a high-build, highly flexible aromatic polyurethane base coat to establish the waterproof foundation. The 8733 Aliphatic is then deployed exclusively as the UV-stable, high-durometer wear course, drastically lowering material costs while maintaining elite structural defense.
Extreme Tire-Torque Anchoring & Pore Sealing:
Must pair with: Elite Vapor-Lock & Pore-Sealing Epoxy Matrix
Why it’s critical: When a 2-ton vehicle brakes or accelerates on a ramp, it transfers massive rotational torque directly to the coating interface. If applied to improperly sealed concrete, this shear stress will violently rip the polyurethane from the slab. This heavy-duty epoxy primer penetrates deep into the capillary network, permanently binding the substrate and establishing an unbreakable molecular anchor that deflects extreme vehicular torque and eliminates out-gassing pinholes.
Vehicular Kinetic Isolation & Chloride Defense:
Must pair with: Architectural High-Performance PU Sealant
Why it’s critical: Parking structures experience massive dynamic deflection under vehicular loads. Unsealed concrete control joints will instantly cause reflective cracking in the rigid wear-course, allowing corrosive de-icing salts to penetrate and destroy the structural rebar. This Class 25 F dynamic polyurethane sealant must be heavily injected into all structural movement joints prior to coating, acting as a high-mass elastomeric shock-absorber that isolates vehicular kinetic energy.
