Resin High-Gloss 2K Metal Body Topcoat

Product Overview

The Acrylic Resin Metal Body Paint 2K Topcoat C-300-1 represents a precision-engineered surface solution co-developed by COOL VI NOBLE, Mixon Color, and SHANGFU. Formulated with an exact 80% concentration of premium acrylic resin and 20% concentrated pigments, this liquid coating delivers a resilient, glass-like finish for automotive panels, marine vessels, industrial machinery, and heavy metal structures. As a foundational element for large-scale surface restoration and original manufacturing, it provides exceptional coverage and a smooth, tactile finish that resists daily abrasion and environmental degradation. Designed to support extensive procurement demands, it accommodates custom corporate color matching and OEM/ODM manufacturing requirements, ensuring a consistent, reliable supply for demanding industrial applications.

Key Features

High-Gloss & Sleek Finish

Beyond basic color application, this topcoat cures to a deeply reflective, mirror-like gloss that feels exceptionally smooth to the touch. The concentrated acrylic resin prevents the dulling effect commonly caused by prolonged UV exposure, acidic rain, and airborne particulates. Vehicles and marine craft maintain a showroom-level luster, presenting a luxurious visual profile that lasts through years of active service.

Fast-Drying & Efficient Construction

Time is a critical metric in professional workshops and manufacturing facilities. Engineered for rapid curing, the C-300-1 formula achieves a touch-dry state in just 30 minutes and a hard-dry finish within 2 hours (at 25℃ and 50% humidity). This accelerated drying cycle dramatically reduces bay-tie-up times. Furthermore, the high-hiding-power formulation requires less material per square meter, maximizing cost-efficiency. Available in industrial-scale packaging, it offers highly competitive procurement advantages for volume-heavy operations.

Superior Resistance Capabilities

Built for punishing environments, the cured film delivers an anticipated outdoor lifespan of 5 to 10 years. It forms an impenetrable barrier against harsh chemical spills, gasoline drips, and abrasive road gravel. This extreme weatherability and physical toughness significantly lower long-term maintenance overhead for fleet operators and vessel owners, protecting the underlying metal from aggressive oxidation and structural rust.

Customizable Colors & Strong Compatibility

To meet exact corporate branding or unique restoration requirements, this topcoat offers precise color-matching services, including a transparent variation. It functions as a core component within a complete, integrated coating system—from surface prep agents and primers to hardeners and clear coats. This systemic compatibility guarantees flawless inter-coat adhesion over existing sanded paints, raw metal, and treated plastics, eliminating the risk of delamination or micro-cracking.

Professional Automotive Repair Performance

Tailored for the exacting standards of collision repair centers, the coating provides exceptional sandability. Once fully cured, technicians can effortlessly level the surface to match original factory textures. The resulting dense film acts as an uncompromising foundation for final compounding and polishing, ensuring a flawless, undetectable transition between repaired zones and original panels.

Usage Guidelines

Mixing Ratio

Precision is paramount for optimal cross-linking. The topcoat must be mixed with the designated 2K Acrylic Enamel Auto Paint Slow Hardener before use; the recommended mixing ratio is strictly 4:1 (topcoat: hardener) by volume to ensure the complete coating system functions in perfect harmony.

Adjust the ratio according to specific application environments: increase the hardener ratio (up to 3:1) for faster curing in cooler climates, or decrease it (up to 5:1) for a longer working time, which is highly suitable for large-area industrial spraying.

Mechanically stir the mixture evenly for 3-5 minutes to ensure full integration of the topcoat and hardener; let it stand for a 10-minute induction period after mixing to eliminate trapped air bubbles.

Surface Preparation

Adhesion relies on meticulous substrate preparation. Clean the metal or automotive surface thoroughly: remove oil, grease, dust, and loose oxidation with a dedicated degreaser and rust remover. For old coatings, mechanically abrade the surface with 400-600 grit sandpaper to remove peeling parts and create a rough mechanical profile for better adhesion.

Wipe the surface with a clean, lint-free cloth dipped in solvent (such as acetone) to remove residual sanding dust and oil, and let it dry completely (drying time ≥ 30 minutes).

Ensure the surface is completely dry (moisture content ≤ 5%) and free of contaminants before application.

Spray Application Steps

• Equipment Setup: Use a professional HVLP spray gun with a nozzle diameter of 1.8-2.2 mm, adjust the air pressure to 0.4-0.6 MPa for optimal atomization.
• Initial Primer Coat: Apply the first coat with a thin thickness (15-20 μm) to ensure foundational grip, then wait 1 hour for solvent evaporation and drying.
• Final Finish Coat: Apply the second coat with a thickness of 30-40 μm to achieve maximum gloss and color depth.
• Technique: Maintain a spraying distance of 20-30 cm from the surface, move the gun horizontally and evenly, avoid staying in one place to prevent drips; overlap each spray pass by 50% for uniform coating.

Curing Process

Establish a controlled environment by curing the coating in a well-ventilated area with a temperature of 15-30℃ and humidity of 40%-60%.

The surface remains vulnerable during the initial phase; do not touch, wash, or polish the surface within 48 hours after application. The coating will be fully cured in 24 hours, and aggressive compounding or polishing can be done after 72 hours (use 1500-2000 grit sandpaper for polishing).

For automotive repair, avoid driving the vehicle in rainy or dusty environments within 24 hours to protect the fresh coating from premature degradation.

Safety Precautions

Respiratory & Skin Protection

• The product contains active solvents, so inhalation of mist or vapor is harmful. Always operate in a well-ventilated spray booth; if mechanical ventilation is insufficient, wear a NIOSH-approved respirator with organic vapor cartridges.
• Wear chemical-resistant gloves (heavy-duty nitrile or rubber), full-body protective clothing, and splash-resistant safety goggles to prevent skin and eye contact. Do not touch lenses or sensitive skin with contaminated gloves.

Fire Safety & Ventilation

• While formulated to meet strict industrial VOC emission standards with eco-friendly formula options available, the liquid solvent remains highly flammable. Keep the product strictly away from open flames, sparks, and high-temperature sources (such as heaters, welding equipment).
• Ensure adequate continuous air extraction during construction to disperse combustible solvent vapor; strictly prohibit smoking in or near the construction area.
• Do not use the product in confined spaces without proper approval and ventilation; rigorously follow “confined space operation regulations” if application in restricted areas is absolutely necessary.

Waste Disposal & Emergency Measures

• Disposal Protocol: Dispose of waste paint, used solvent washes, and empty containers according to local environmental and hazardous waste regulations; never pour waste liquid into municipal water sources, soil, or sewers.
• Dermal Contact: If the topcoat comes into contact with skin, rinse immediately with plenty of industrial soap and water; if irritation persists, seek medical attention.
• Ocular Contact: If the topcoat enters the eyes, flush with clean water continuously at an optic wash station for 15 minutes, do not rub the eyes, and seek medical help immediately.
• Accidental Ingestion: In case of accidental ingestion, do not induce vomiting; drink plenty of water and seek medical attention promptly, bringing the original product label or Safety Data Sheet (SDS) for reference.
