YX-T901 Room-Temperature Curing Anti-Corrosion Silicone-Based Coating

Product Introduction:

YX-T901 It is a room-temperature curing, anti-corrosion silicone-based coating, which is superior to... YX-T70X Fast curing speed 3 Twice, than YX-T60X The film thickness is greater. Using polysilazane resin as a binder and compounding it with color pigments, silicate materials, reinforcing silica powder, and other ingredients, this material can be applied in areas such as corrosion protection for salt mining regions and coastal facilities.

Special features:

· Excellent adhesion, water resistance, weather resistance, and salt corrosion resistance (neutral salt spray resistance exceeding 5,000 hours);

· The two-component coating is entirely composed of silicon-based materials and contains no harmful solvents. Polysilazane cures at room temperature in the presence of moisture.

· Silicon-based coatings can withstand high temperatures of 250℃ for short periods and exhibit thermal shock resistance at 150℃ (without cracking under repeated cycles of heating and cooling).

Application areas:

· Protection and repair of pipeline outer walls, steel frame structures, and metal platforms—suitable for corrosion prevention in salt mining facilities.

· Coastal machinery such as quay cranes and safety guardrails—particularly in areas subject to coastal corrosion—stand out in terms of coating repair.

· Anti-corrosion coating for the outer wall of temperature-resistant facilities below 150℃.

Suitable for hard substrates such as steel, alloys, and ceramics, and exhibits excellent adhesion to most coatings.

Construction Instructions:

1 — Substrate Pre-treatment:

· The substrate surface should be free of oil, water stains, dust, particles, dirt, and soft layers.

· It is recommended to grind or sandblast the metal substrate to at least St3 grade, free of oxide scale (GB/T 30790.4-2014).

2 Construction method:

· Coating can be applied by spray coating, dip coating, brush coating, or roll coating. The original paint should have its viscosity adjusted for air-assisted spray application.

· Open the packaging container and stir components A and B separately using a spatula or stirring rod. If the sediment at the bottom of pigment paste A can be easily stirred evenly, the product is qualified. The mixed base coat must be filtered through a 100-mesh sieve before it can be used.

· For large-area spraying, use a nozzle with a 1.5 mm diameter; for small-area spraying, use a nozzle with a 1.0 mm diameter. The air pressure should be between 0.15 and 0.2 MPa. The spray spacing should be no less than 200 mm, and the spray direction should generally be perpendicular to the surface being coated. Maintain a consistent moving speed of the spray gun. Before starting the actual application, test and calibrate the coating thickness on a sample board; a dry film thickness of 80–120 microns is ideal.

· During spraying operations, the substrate temperature should be below 50℃, and adequate ventilation must be ensured. Clean the spray gun with a thinner.

· The surface of the paint film should be smooth and even, with no defects such as sagging or pinholes. If the dry film thickness is insufficient, additional spray coats can be applied.

3 · Curing method:

· Place the coated sample in an oven and heat it at a temperature of 180–230℃ for 30 minutes to achieve rapid curing. Use a calibrated film thickness gauge to measure the film thickness and inspect the appearance of the coating film. This method is applicable only for calibrating construction parameters. ；

· After construction is completed, the coating cures by absorbing moisture from the ambient air. The paint film becomes touch-dry in 4 hours, surface-dry in 18 hours, and gradually fully cured in more than 5 days. Being in a humid and high-temperature environment after surface drying helps to shorten the curing time. 。

This product contains ammonia that is physically adsorbed or chemically bonded. When handling the material, you should take the following measures: foot Sufficient preventive measures.

Dilution and Preparation:

Dilution: Diluents can include lipids (butyl acetate, propylene glycol methyl ether acetate), alkanes (heptane), ethers (dibutyl ether), aromatics (xylene), and more. You may also consult our company for specialized diluents. This product is effective against... Water Sensitive; may ignite upon contact with oxidizers, alcohols, acids, and bases. birth To minimize the moisture content, select the diluent mentioned above and use it to the greatest extent possible. Diluting the original paint may increase the risk of sagging in the coating; therefore, minimize the use of thinner as much as possible.

Configuration: A The group is a color paste. B The group consists of polysilazane material, weighed according to the required amount. A ： B = 100 : 25 Once thoroughly mixed, it becomes the original paint. For spraying, it’s recommended to use the original paint directly; if dilution is required for construction, then... 100 No more than [amount] of Kechuan paint may be added. 20 K solvent—products exposed to air should be... 6 Use up within the hour.

Security and Storage:

·Due to product characteristics, a small amount of ammonia gas may be generated. Paint that has been opened but not fully used must be tightly sealed in its container. If necessary, purge the container with nitrogen before sealing it to prevent the ingress of contaminants and moisture.

· The storage temperature for unopened products should be ensured to be: 30 Below ℃, shelf life is: 12 months;

· The opened product is well-sealed, and the storage temperature should be maintained at: 30 Below ℃, the shelf life is: 6 months;

The storage environment should be dry, cool, well-ventilated, and kept away from heat sources and ignition sources. This product is sensitive to... Water Sensitive; may ignite upon contact with oxidizers, alcohols, acids, and bases. birth React and store with appropriate spacing.

Cleaning and Recycling:

Cleaning:

· Construction equipment should be cleaned immediately after use (before the product has cured);

· Thinners (such as butyl acetate and heptane) can be used to clean residual products from equipment;

· The cured product needs to be treated with a strong alkaline solution (such as 30% Soak and clean with sodium hydroxide solution or clean by sandblasting.

Recycling:

· The leftover materials from the application of this product must not be mixed with other liquids or solids. They should be collected in a dry, pressure-resistant container (preferably an iron container) and clearly labeled.

·When handling waste containers bearing this product’s label, they must be disposed of in accordance with applicable regulations.

· During transportation, waste containers must be sealed.
