Two-component polyurethane anticorrosion paint

  Poly   Urethane   Ester Anti Corrosion Finish Paint

I. Product Introduction:

Polyurethane anti-corrosion finish paint is a two-component, high-performance heavy-duty anti-corrosion coating that cures into a film through special chemical reactions, possessing excellent adhesion, wear resistance, chemical corrosion resistance, and weather resistance. It is a two-component self-drying paint processed from aliphatic isocyanate components, combined with high-grade acrylic resin, high-quality pigments, additives, and solvents through a specific process. It has excellent elasticity, tensile strength, weather resistance, chemical corrosion resistance, and aging resistance.

II. Product Features ：

Good chemical resistance and water resistance, capable of resisting the erosion of various chemical substances, ensuring the long-term stability of the coating.

Resistant to mineral oils, vegetable oils, petroleum solvents, and other petroleum products, thus particularly suitable for certain specific environments and application scenarios.

The paint film is tough and has good gloss, making the coated surface hard, smooth, and aesthetically pleasing.

Fast drying, capable of rapid curing, shortening the construction period and improving construction efficiency.

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

Possesses a strong and tough paint film and high adhesion, capable of firmly adhering to the substrate surface without easily peeling off.

Has excellent wear resistance and corrosion resistance, capable of protecting the substrate from mechanical damage and chemical corrosion.

Can be applied with epoxy-based intermediate or primer coats to provide long-lasting anti-corrosion protection, with a corrosion protection period that can even reach 10 years or more.

III. Product Uses:

Polyurethane anti-corrosion finish paint possesses various excellent properties such as a tough film, rich gloss, strong adhesion, water and wear resistance, and corrosion resistance, making it widely used in various fields. Below are some main uses of polyurethane anti-corrosion finish paint:

Wood furniture: Polyurethane anti-corrosion finish paint can be used for coating wood furniture, such as wooden doors, window frames, floors, cabinets, etc., providing good protection and decorative effects.

Metal surfaces: Polyurethane anti-corrosion finish paint can also be used for coating metal surfaces, such as steel, aluminum, galvanized sheets, etc., capable of preventing metal rust and corrosion while enhancing aesthetics.

Automotive, aerospace, machinery, and other fields: Polyurethane anti-corrosion finish paint is also widely used in these fields, such as car bodies, vehicles, aircraft shells, mechanical equipment, etc., capable of providing excellent anti-corrosion protection and decorative effects.

Electrical appliances, instruments, and meters: Polyurethane anti-corrosion finish paint can be used for coating the casings and internal parts of electrical appliances, instruments, and meters, providing good insulation and chemical corrosion resistance.

Petrochemical field: Polyurethane anti-corrosion finish paint can be used for anti-corrosion coating of petrochemical facilities, such as oil storage tanks, pipelines, reactors, etc., capable of withstanding chemical erosion and harsh environments such as high temperature and high pressure.

In addition, polyurethane anti-corrosion finish paint can also be used in hydraulic engineering, ships, general chemical corrosion, etc., possessing good weather resistance, water resistance, and chemical resistance.

VI. Construction Process and Steps:

Preparation before construction:

Substrate treatment: Ensure the substrate is dry, clean, free of oil stains, rust, dust, etc. If necessary, carry out grinding, rust removal, cleaning, and other treatments.

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

Construction environment : Ensure the construction environment's temperature and humidity meet requirements, and avoid construction in adverse weather conditions such as rain, snow, or strong winds.

Construction methods and techniques

Application method: Construction can be carried out by spraying, brushing, rolling, etc. Choose the appropriate construction method according to actual conditions.

Number of coats: Generally recommended application of 2-3 coats, each layer should be fully dry to ensure adhesion between coatings.

Application thickness : The thickness of each coating layer should be controlled within the specified range to avoid affecting the anti-corrosion effect due to being too thick or too thin.

Precautions: During construction, avoid defects such as sagging, bubbling, or orange peel in the coating, and ensure the coating surface is flat and smooth.

Quality control and inspection standards:

Quality checks should be performed after each process is completed to ensure compliance with design requirements and relevant standards.

The coating should be uniform, free of missed spots, bubbles, sagging, and other phenomena.

After the coating dries, performance tests such as adhesion, impact resistance, and salt spray resistance should be conducted to ensure compliance with 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 safety glasses, gloves, and masks.

Coatings should be stored in a well-ventilated, dry place, away from ignition sources and heat sources.

During construction, avoid coating splashes into eyes or skin. If accidental contact occurs, rinse immediately with clean water.

Coating maintenance and update methods

Regularly inspect the coating condition. If damage, aging, or other phenomena are found, repair or reapply the coating promptly.

When repairing the coating, choose the same coating material as the original to ensure the repaired coating matches the original.

For areas subject to long-term corrosion, consider using a more corrosion-resistant coating for recoating.

VII. Note Meaning Matter Item

Before use, mix the paint and curing agent according to the required ratio. Prepare only as much as needed, and use after stirring evenly. 8 use within hours;

Products should be stored in a cool, well-ventilated place, protected from direct sunlight, and kept away from ignition sources and heat sources;

Keep the construction process dry and clean, and strictly avoid contact with water, acids, alcohols, alkalis, etc.; after mixing the paint, the curing agent packaging drum must be tightly sealed to prevent gelling;

Operators should wear safety masks and gloves to avoid contact with skin or eyes. In case of accidental contact, rinse with clean water.
