Ultra-thin (Steel Structure) Fire-Resistant Paint Coating

Ultra-Thin Fireproof Paint - Ultra-Thin Steel Structure Fireproof Coating / Excellent Decorative Properties (Crown Brand Paint Sales 152_0825_6966 Manager Sun) Ultra-thin fireproof coating is a special coating specifically used on substrates such as steel structures and wood. Its core feature is the combination of an ultra-thin coating (typically ≤3mm in thickness) and high-efficiency fireproof performance.

Basic Characteristics

• Ultra-Thin Thickness: The dried coating thickness is typically between 0.5-3mm, significantly lower than thick-type (>10mm) or thin-type (3-7mm) fireproof coatings, making it suitable for places with strict aesthetic or space requirements.

• Fireproof Principle: When exposed to fire, the coating rapidly expands to form a dense foamed carbonized layer (up to dozens of times the original thickness), isolating oxygen and delaying the temperature rise of the substrate, protecting the steel structure from losing load-bearing capacity for 1-2 hours (specific time depends on the product grade).

• Decorative Properties: The surface can be adjusted to various colors, providing both anti-corrosion and decorative functions without the need for an additional topcoat.

Application Scenarios

• Steel Structure Buildings: Steel beams, columns, etc., in stadiums, airports, and high-rise buildings (must comply with the "GB 14907-2018" standard).

• Industrial Facilities: Pipelines and equipment supports in oil platforms and chemical plants.

• Special Requirement Sites: Space-restricted areas such as tunnels and ship cabins.

Differences from Other Fireproof Coatings

Key Construction Points

• Substrate Treatment: Requires thorough rust removal (Sa2.5 grade) and application of anti-rust primer.

• Coating Method: Spraying, brushing, or rolling; multiple layers require intervals for drying.

• Environmental Requirements: Avoid working in rain, snow, low temperatures (<5°C), or high humidity (>85%).
