I. Product Introduction:

Polyurethane anti-corrosion topcoat is a two-component, high-performance heavy-duty anti-corrosion coating that is cured into a film through a special chemical reaction. It has excellent adhesion, abrasion resistance, chemical corrosion resistance and weather resistance. It is a two-component self-drying coating based on aliphatic isocyanate component, acrylic resin, high-quality pigments, additives and solvents through a specific process. It has excellent elasticity, tensile resistance, weather resistance, chemical corrosion resistance and aging resistance.

II. Product Features:

Good chemical resistance and water resistance, able to resist the erosion of various chemical substances, ensuring the coating remains stable for a long time.

Resistant to mineral oils, vegetable oils, petroleum solvents and other petroleum products, making it particularly suitable for certain specific environments and usage scenarios.

The paint film is tough and has good gloss, making the coating surface hard and smooth, with good aesthetics.

Fast drying, able to cure quickly, shortening the construction cycle and improving construction efficiency.

The paint film is heat-resistant, does not soften or become sticky, and can maintain stable performance even in high-temperature environments.

It has a strong and tough paint film and high adhesion, which can firmly adhere to the surface of the substrate and is not easy to fall off.

It has excellent abrasion resistance and corrosion resistance, which can protect the substrate from mechanical damage and chemical corrosion.

It can be coated with epoxy intermediate paint or primer to provide long-term anti-corrosion protection, and the anti-corrosion period can even reach more than 10 years.

III. Product Uses:

Polyurethane anti-corrosion topcoat has many excellent characteristics, such as tough paint film, full gloss, strong adhesion, water and abrasion resistance, and corrosion resistance, so it is widely used in various fields. The following are some of the main uses of polyurethane anti-corrosion topcoat:

Wooden Furniture: Polyurethane anti-corrosion topcoat can be used for coating wooden furniture, such as wooden doors, window frames, floors, cabinets, etc., which can provide good protection and decorative effects.

Metal Surface: Polyurethane anti-corrosion topcoat can also be used for coating metal surfaces, such as steel, aluminum, galvanized sheets, etc., which can prevent metal from rusting and corroding, and improve aesthetics.

Automobiles, Airplanes, Machinery and Other Fields: Polyurethane anti-corrosion topcoat is also widely used in these fields, such as automobile bodies, transportation vehicles, aircraft shells, mechanical equipment, etc., which can provide excellent anti-corrosion protection and decorative effects.

Electrical Appliances, Instruments and Meters and Other Fields: Polyurethane anti-corrosion topcoat can be used for coating the shells and internal parts of electrical appliances, instruments and meters, etc., which can provide good insulation performance and chemical corrosion resistance.

Petrochemical Field: Polyurethane anti-corrosion topcoat can be used for anti-corrosion coating of petrochemical facilities, such as oil storage tanks, oil pipelines, reactors, etc., which can withstand the erosion of chemical substances and harsh environments such as high temperature and high pressure.

In addition, polyurethane anti-corrosion topcoat can also be used in water conservancy projects, ships, general chemical corrosion and other aspects, with good weather resistance, water resistance and chemical resistance.

VI. Construction process and steps:

Preparation before construction:

Base treatment: Ensure the base is dry, clean, free of oil, rust, dust, etc. If necessary, perform grinding, rust removal, cleaning, and other treatments.

Paint preparation: Mix the main agent and curing agent of polyurethane anti-corrosion topcoat evenly according to the ratio, and stir until there are no particles or bubbles.

Construction environment: Ensure that the construction environment temperature and humidity meet the requirements, and avoid construction in severe weather such as rain, snow, and strong winds.

Construction methods and techniques

Construction method: Spraying, brushing, roller coating, and other methods can be used for construction. Choose the appropriate construction method according to the actual situation.

Number of construction layers: It is generally recommended to apply 2-3 layers, and each layer should be fully dried to ensure the adhesion between the layers.

Construction thickness: The thickness of each coating layer should be controlled within the specified range to avoid excessive thickness or thinness affecting the anti-corrosion effect.

Precautions: During the construction process, avoid defects such as sagging, blistering, and orange peel on the coating, and ensure that the coating surface is smooth and flat.

Quality control and inspection standards:

Quality inspection should be carried out after each process is completed to ensure that it meets the design requirements and relevant standards.

The coating should be uniform, without omissions, bubbles, or sagging.

After the coating is dry, perform performance tests such as adhesion, impact resistance, and salt spray resistance to ensure that it meets the design requirements.

Safety production management and preventive measures:

Obvious safety warning signs should be set up at the construction site, and necessary safety measures should be taken.

Operators should wear protective equipment, such as protective glasses, gloves, and masks.

The paint should be stored in a well-ventilated and dry place, away from fire and heat sources.

Avoid paint splashing into eyes or skin during construction. If it accidentally occurs, rinse with clean water in time.

Coating maintenance and update methods

Regularly check the coating condition. If damage or aging is found, repair or recoat it in time.

When repairing the coating, choose the same paint as the original coating to ensure that the repaired coating is consistent with the original coating.

For parts that are subject to long-term corrosion, consider using more corrosion-resistant paint for renewal coating.

VII. Precautions:

Before use, mix the paint and curing agent according to the required ratio, mix as much as you use, stir well and use it up within 8 hours;

The product should be stored in a cool and ventilated place, avoid direct sunlight, and isolate it from fire and heat sources;

Keep the construction process dry and clean, and strictly prohibit contact with water, acid, alcohol, alkali, etc.; the curing agent packaging barrel must be tightly closed after mixing the paint to avoid gelling;

Operators should wear safety protective masks and gloves to avoid contact with skin or eyes. If contact occurs accidentally, rinse with clean water.
