Common heat-resistant paint shows the degradation of corrosion resistance when it's left outside for long term without bake at Room Temperature (RT).

Long term exposure type was improved the defect, the degradation of corrosion, and the improved version shows excellent heat and corrosion resistance even if heat is charged after the long term outdoor exposure at room temperature.

Characteristics

  • Feasible to use at the object temperature from 100 - 600℃.
  • Excellent corrosion resistance at RT before bake.
  • One-component type and excellent workability by brush & spray.

Application

Applicable to the plant which needs long term after coating before plant operation.

  • Apply SL thinner for dilution.
  • DFT (Dry Film Thickness) : Minimum film thickness to secure property.
  • Above products are made to order.
  • Basically these products are applied for outer only hence it may not be feasible to maintain enough property if applied for inner.

Caution on the application of Long term exposure type
  1. Substrate surface treatment : Remove oil from substrate surface by thinner then implement blast shot, ISO Sa 2.5 min.
    In case that blast shot is not feasible, apply sanding machine and remove foreign matters such as black scale, old paint film, and rust then implement surface treatment better than ISO St.3.0 .
    After treatment of substrate, remove dirts by air blow then implement undercoat application.
    For 400℃ and 600℃ type, implement a blast shot better than ISO Sa 2.5 .
  2. Refrain from applying at below 5℃ or humidity higher than 85%.
  3. SZ-1200 is applied by airless spray after blast shot. (Better than ISO Sa 2.5)
  4. In case that interval is out of specification, too long, apply sanding to obtain rough surface then implement application.
  5. Paint usage is fluctuated by shape of coating object, surface condition, and coating condition.
  6. When can is opened, confirm the condition of settling in the bottom then agitate well to be homogenious.
  7. Store in a dangerous goods warehouse with tightly sealed at good ventilation and prohibition of flame.
