• VOC compliant to current AIM regulations

Product Specification

Drying Times

• These times are based on a 75 microns dry film thickness. Higher film thickness, insufficient ventilation or cooler temperatures will require longer cure times and could result in solvent entrapment and premature failure
• The general requirement is a 24-hour cure for Carboline epoxy intumescent applications. Maximum recoat time is unlimited. Recoat intervals may vary from those listed above when using under intumescent fireproofing products. Consult Rawlins on Tech - 0113 2455450 (option 2) or [email protected] for recommended cure times before applying Carboline intumescent products
• Must have a clean, dry surface free of chalk, zinc salts, etc. per typical good painting practices. Consult Rawlins on Tech - 0113 2455450 (option 2) or [email protected] for specific information

Surface Preparation

General

• Surfaces must be clean and dry
• Employ adequate methods to remove dirt, dust, oil, and all other contaminants that could interfere with adhesion of the coating

Steel

• SSPC-SP6 with a 25-75 microns surface profile
• SSPC-SP2 or SP3 with a roughened surface for touch-up
• When using under fireproofing products, defer to the primer surface preparation requirements in the product data sheet of the fireproofing product

Application Methods

Application Conditions

• Industry standards are for the substrate temperatures to be 3°C above the dew point
• This product simply requires the substrate temperature to be above the dew point
• Condensation due to substrate temperatures below the dew point can cause flash rusting on prepared steel and interfere with proper adhesion to the substrate
• Special application techniques may be required above or below normal application conditions which are as follows: material 16-29°C, surface and ambient 16-32°C and humidity 0% - 90%.

Health and Safety

Clean Up

• Use Thinner 2 or Acetone
• In case of spillage, absorb and dispose of in accordance with local applicable regulations

Safety

• Read and follow all caution statements on this product data sheet and on the SDS for this product and use personal protective equipment as directed
• Employ normal workmanlike safety precautions
• Hypersensitive persons should wear protective clothing, gloves and use protective cream on face, hands and all exposed areas.

Ventilation

• When used in enclosed areas, thorough air circulation must be used during and after application until the coating is cured.
• The ventilation system should be capable of preventing the solvent vapor concentration from reaching the lower explosion limit for the solvents used
• In addition to ensuring proper ventilation, appropriate respirators must be used by all application personnel
• This product contains flammable solvents. Keep away from sparks and open flames
• All electrical equipment and installations should be made and grounded in accordance with regulations
• In areas where explosion hazards exist, workmen should be required to use non-ferrous tools and wear conductive and non-sparking shoes
