Acid resistance is added to heat resistance to satisfy the condition where Acid resistance is demanded at dry & gas condition and at wet condition with high humidity.

There are several paint types to meet the various heat and acid resistant condition; therefore, please contact our sales staff for selection.

Application

Applied for plant equipment, chimney, duct, and inner of various equipment requesting heat and acid resistance.

«Two-component Heat and Acid resistance paint»

Characteristics
AX type : Two-component epoxy modified silicone resin type. Excellent for heat, acid, oil, and corrosion resistance.
Applied for oil tank inner (liquid temp:below 75℃), duct & gas cooling tower inner under wet gas condition.
AI type : Two-component epoxy modified silicone paint which is heat & acid resistance improved version of AX type.
This product shows excellent warm water, salt water, and corrosion resistance too.
Also applied for inner of chimney, duct, heat exchanger, and FGD equipment flue where acid wet gas atomosphere is expected.

Package

16㎏ set, 5㎏ set (Designated thinner : 16L, 4L)

∗No separate sales of paint and hardener.

  • Airless spray only. HB is a high film thickness type and applied for top coat.
  • Apply AX-thinner for AX type and AI-thinner for AI type.
  • DFT (Dry Film Thickness) : Minimum film thickness to secure property.
  • Above products are made to order.

Caution on the application of Heat and Acid resistance type
  1. Substrate surface treatment : Remove oil from substrate surface by thinner then implement blast shot, ISO Sa 2.5 min.
    After treatment of substrate, remove dirts by air blow then implement undercoat application.
  2. Refrain from applying at below 5℃ or humidity higher than 85%.
  3. In order to improve affinity with substrate, brush for 1st undercoat is recommended.
  4. In case that interval is out of specification, too long, apply sanding to obtain rough surface then implement coating.
  5. In case current film was left at the recoat, implement sanding by a motor tool to obtain rough surface.
  6. Paint usage is fluctuated by shape of coating object, surface condition, and coating condition.
  7. When can is opened, confirm the condition of settling in the bottom then agitate well to be homogenious.
  8. Store in a dangerous goods warehouse with tightly sealed at good ventilation and prohibition of flame.
