DIRECT-TO-METAL G-THANE 4:1:1 POLYURETHANE COATING
G-THANE 4:1:1 Direct-to-Metal Polyurethane Coating
High-Performance Industrial & Automotive Protection
G-THANE 4:1:1 is a premium, two-component, direct-to-metal (DTM) aliphatic polyurethane coating engineered to deliver superior gloss retention, color stability, and robust corrosion resistance. By combining primer and topcoat properties into a single, high-build formula, G-THANE eliminates multi-step coating processes without compromising on long-term substrate protection. [1, 2]
Key Industries & Applicationsđźš— Automotive & Fleet Maintenance
G-THANE 4:1:1 significantly optimizes throughput in automotive refinishing, commercial fleet maintenance, and heavy-duty transport manufacturing. [1]
- Self-Priming Efficiency: Eliminates separate primer application and curing steps, drastically reducing booth time and labor costs.
- Direct-to-Metal Bonding: Formulated with advanced adhesion promoters that bond instantly to properly prepared steel, aluminum, and OEM finishes.
- Fast Curing: Accelerates assembly, handling, and turnaround times, getting commercial vehicles back on the road faster.
🏗️ General Steel & Industrial Construction
From light commercial fabrications to heavy industrial infrastructure, G-THANE provides versatile, highly durable protection against harsh environmental exposures. [1, 2]
- Scalable Application: Tailored for everything from small shop-applied components to large-scale structural steel installations.
- Corrosive Resistance: Formulated to withstand UV radiation, chemical splashes, moisture, and mechanical abrasion.
- Streamlined Inventory: One product serves as both the primer and finish coat, simplifying job-site logistics and minimizing product waste. [1, 2]

- Full Chemical Cure: 7 days
- Overcoating Window: Minimum 4 hours; Maximum 24 hours (Light scuffing required if maximum window is exceeded)
Surface Preparation & Application🛠️ Surface Preparation
To ensure maximum direct-to-metal bonding and performance, all substrates must be clean, dry, and free of contamination.
- Mild Steel: Remove all oil, grease, and mill scale. Abrasive blast-clean to ISO 8501-1 Sa 2½ to create a uniform 40–50 micron profile. For small or light industrial projects, clean via mechanical sanding or wire-brushing to St 3 minimum. [1]
- Aluminum & Galvanized Steel: Clean with an appropriate degreaser, follow with a light hand-abrasion (using a non-metallic pad) to remove any zinc salts or oxidation, and ensure a clean profile. [1]
- Existing Coatings: Ensure the old finish is sound, clean, and soundly adhered. Scuff-sand with P320–P400 grit to create a mechanical anchor profile before application.
🎛️ Application Methods
- Conventional / Airless Spraying: Highly recommended for optimal automotive and large-scale industrial finishes. Use a 1.4mm to 1.8mm nozzle setup for gravity-fed equipment.
- Brush or Roller: Suitable for small components, touch-ups, or stripe-coating edges. Multiple coats may be required to achieve target dry film thickness.
