Heavy-duty Anti-corrosion Coatings

Overview

• This elastic anti-corrosion coating, developed using silicone materials as the film-forming substance through a specialized process and cured by water vapor at room temperature, provides excellent corrosion resistance and aging resistance for steel structural products under extreme climatic conditions.

Product features

• Exemplary outdoor weather resistance, UV resistance, and a service life of up to 25 years.
• Exhibits excellent resistance to extreme temperatures (-50°C to 200°C) and can withstand prolonged cycles of thermal cycling.
• After curing, the coating exhibits strong adhesion and does not exhibit peeling or detachment.
• The coating exhibits excellent elasticity and ductility; regardless of how the substrate is bent or deformed, no wrinkles, cracks, or detachment will occur.

Application method

• Surface treatment: The coated steel surface must be thoroughly cleaned of oil stains, oxide scales, rust, and old coatings. Shot blasting or sandblasting may be employed, with a rust removal grade of at least Sa1 or St2 required. For concrete structures, surface dust should be removed directly; water stains must be avoided. For steel structures with existing coatings, the adhesion between the old coating and this product must be tested.
• Construction Conditions: The construction temperature should be maintained between 5–35°C under adequate ventilation. Construction is strictly prohibited during adverse weather conditions such as rain, snow, fog, strong winds, or high humidity. Additionally, similar weather conditions should be avoided within 6 hours after the commencement of work.
• Application method: Single-component paint; use directly after mixing. Recommended application rate: 0.35 kg/m²; number of application layers: 2; dry film thickness: 100 μm. The actual paint quantity should be confirmed by the laboratory according to requirements.
• Safety Instructions: The construction site is equipped with adequate ventilation facilities. Personnel must take protective measures, including wearing gloves, masks, and protective goggles. In case of accidental exposure to the eyes or skin, immediately rinse with water. Seek medical attention promptly if discomfort occurs. Smoking and open flames are strictly prohibited at the construction site.
