System Selection
Choose a coating system based on operating temperatures, exposure conditions and functional requirements.
BLA-400 for black matte silicone coating up to +400°C dry heat BLA-600 for aluminum silicone coating up to +650°C dry heat on bare steel 800°C high-temperature paint for very high-temperature industrial equipment BAYD-JY20B and BAYD-HR900 for insulation or easy-clean special functions
Key Selection Questions
Consider continuous and peak operating temperatures, heating and cooling cycles, and curing conditions when selecting your coating system.
Service Temperature
Confirm whether the project needs +400°C dry heat, +650°C dry heat, 800-950°C resistance, insulation, or easy-clean performance.
Dry Heat vs. Other Exposure
BLA-400 and BLA-600 temperature ratings are dry heat references. Water, oil, chemicals, humidity, and thermal cycling should be reviewed separately.
Surface Preparation
Steel surfaces may need cleaning, degreasing, salt removal, blast cleaning to Sa2.5, phosphating, or roughening depending on the product route.
Film Thickness & Cure
High-temperature systems are thin-film products. Target dry film thickness, natural drying, heat curing, and final hardness timing must be confirmed.
Application Method
Spray, airless spray, air spray, brush, roller, compressed air spray, and electrostatic spray are product-specific and should not be treated as interchangeable.
Special Functions
Electrical insulation, non-stick behavior, cleanability, weathering resistance, and adhesion on metal substrates should be matched to the exact product.

Application Workflow
Follow the key steps in surface preparation, application, curing and inspection.
Confirm Temperature Profile
Define peak temperature, continuous temperature, dry heat condition, thermal cycle, heating frequency, and whether insulation or easy-clean function is required.
Review Substrate
Confirm steel, zinc silicate coated steel, aluminum, metal component, electronic component, pipe, chimney, heating equipment, or repaired old coating.
Prepare the Surface
Remove oil, grease, salt, dirt, dust, rust, and loose coating. Use blast cleaning, phosphating, degreasing, or roughening where the selected product requires it.
Prepare the Coating
Stir, redisperse, thin, filter, or mix according to product requirements. JY20B and HR900 should be filtered through 150 mesh after redispersion.
Apply Thin Film
Apply by the verified method for the selected product, such as airless spray, air spray, brush, roller, compressed air spray, or electrostatic spray.
Dry, Cure & Inspect
Confirm dust dry, touch dry, recoat window, heat-curing condition, final hardness timing, appearance, adhesion, and readiness for service.
Suitable Substrates
Identify compatible coating systems based on your substrate, existing coating and surface preparation conditions.
Steel surfaces prepared to Sa2.5 where high-temperature silicone coatings or very high-temperature paint are being considered.
