Surface Preparation


Recommended Substrate Conditions and Temperatures

Substrate conditions

  • Steel; blast cleaned to a minimum of ISO-Sa2½, blasting profile 40 – 70 µm (1.6 – 2.8 mils)
  • Suitable primer (DIMETCOTE 11) must be dry and free from any contamination

 

Substrate Temperature & Application Conditions


  • Surface temperature during application should be between 5°C (41°F) and 60°C (140°F)
  • Surface temperature during application should be at least 3°C (5°F) above dew point
  • Ambient temperature during application and curing should be between 5°C (41°F) and 50°C (122°F)

Application


Instructions for Use

  • Stir well before use
  • The temperature of the paint should preferably be above 15°C (59°F), otherwise extra thinner may be required to obtain application viscosity
  • Adding too much thinner results in reduced sag resistance

 

Air spray


Recommended thinner

Volume of thinner

  • 0 - 5%, depending on required thickness and application conditions

Nozzle orifice

  • 1.8 – 2.0 mm (approx. 0.070 – 0.079 in)

Nozzle pressure

  • 0.3 - 0.4 MPa (approx. 3 - 4 bar; 44 - 58 p.s.i.)

 

Airless spray


Recommended thinner

  • THINNER 21-06

Volume of thinner

  • 0 - 5%, depending on required thickness and application conditions

Nozzle orifice

  • Approx. 0.33 – 0.48 mm (0.013 – 0.019 in)

Nozzle pressure

  • 15.0 - 18.0 MPa (approx. 150 - 180 bar; 2176 - 2611 p.s.i.)

 

Brush/roller


Recommended thinner

  • THINNER 21-06

Volume of thinner

  • 0 – 2%

Notes:

  • Adequate ventilation must be maintained during application and curing
  • Drying and curing times are dependent on air and steel temperature, applied film thickness, ventilation and other environmental conditions

Safety Precautions


  • This is a solvent-borne paint and care should be taken to avoid inhalation of spray mist or vapor, as well as contact between the wet paint and exposed skin or eyes
  • Since improper use and handling can be hazardous to health and cause of fire or explosion, safety precautions included with Product Data/Application Instruction and Material Safety Data Sheet must be observed during all storage, handling, use and drying periods
