SC H.R. Silver Paint 250°C – High-Temperature Corrosion Resistant Coating

SC H.R. Silver Paint 250°C is based on a phenolic and bituminous binder system, providing exceptional mechanical strength and chemical durability. The coating cures at room temperature and develops a hard, tough film upon heating to 250°C. Once cured, it offers unmatched resistance to corrosion, moisture, and temperature variations — making it ideal for industrial and engineering applications.

This paint is designed to withstand continuous temperatures up to 200°C and intermittent heat exposure up to 250°C, making it suitable for exhaust systems, heat drums, furnaces, silencers, ovens, chimneys, and other heat-conducting components.

Key Features & Benefits:

  1. High Heat Resistance:

    • Withstands temperatures up to 250°C.

    • Maintains film integrity under high heat and cyclic temperature changes.

  2. Superior Corrosion Protection:

    • Forms a tough, impermeable layer that prevents rust and oxidation.

    • Provides protection against atmospheric, industrial, and marine environments.

  3. Chemical & Solvent Resistance:

    • Excellent performance against mild acids, alkalis, and salts.

    • Protects surfaces from chemical fumes and industrial gases.

  4. Mechanical Durability:

    • Exhibits high scratch hardness (1500–2000 gm).

    • Withstands abrasion, impacts, and handling during operation.

  5. Weather & Humidity Resistant:

    • Passes 140-hour humidity test with no blistering or rusting.

    • Ensures long-lasting protection in outdoor and humid environments.

  6. Aesthetic Finish:

    • Available in Silver or Black matte finishes.

    • Provides smooth, uniform coating for industrial aesthetics.

Applications:

SC H.R. Silver Paint 250°C is suitable for a wide range of industrial applications including:

  • Heat drums and silencers
  • Exhaust systems and mufflers
  • Industrial ovens and furnaces
  • Boilers and heat exchangers
  • Chimneys, flue pipes, and ducts
  • Engine parts and heat-conducting components

Its versatility makes it ideal for use in automotive, manufacturing, power plants, and process industries.

Curing Schedule:

  • Air drying at room temperature.

  • Complete curing achieved upon heating the surface to 250°C.

Temperature Resistance:

  • Continuous: 200°C (Dry heat)
  • Intermittent: 250°C (Dry heat)

Weatherability: Very Good
Flexibility: Good
Abrasion Resistance: Good

Surface Preparation:

Proper surface preparation is essential for optimal performance.

  1. Steel Surfaces: Remove grease, oil, and contaminants using degreasing solvent.

  2. Blasting: For best results, blast clean to Sa 2½ (Swedish Standard SIS 05 5900).

  3. Manual Cleaning: If blasting is not possible, use mechanical tools and wire brushing to achieve St 2 standard.

  4. Ensure the surface is completely clean and dry before applying the primer coat or SC H.R. Silver Paint.

Application Procedure:

  1. Mix the contents thoroughly before and during application.

  2. Apply by brush, roller, or spray gun with recommended thinner.

    • Brush/Roller: Up to 5% thinner if required.

    • Spray: Up to 10–15% thinner depending on spray conditions.

  3. Allow overnight drying before recoating.

  4. Do not apply when:

    • Temperature < 10°C or > 50°C.

    • Relative humidity > 90%.

    • During rain, fog, or mist conditions.

Clean brushes and spray equipment immediately after use with SC H.R. Thinner.

Storage & Shelf Life:

  • Shelf life: 6 months in unopened containers under cool, dry conditions.
  • Store away from direct sunlight and heat sources.

Health & Safety:

Use adequate ventilation during application. Avoid inhalation of vapors and contact with skin or eyes. Follow standard industrial safety precautions.
