Surface preparation
  • Surface should be clean, dry, and free of dirt, rust, oil, soluble salt or water, grease, wax, loose paint, and any other contaminants.
  • We recommend to use minimum commercial preparation standards as SSPC-SP6 or SSPC-SP3.
  • SSPC-SP6 sandblasting standard would be much more appropriate and strongly recommended for better corrosion resistance.
  • Surface temperature must be at least 3oC higher to the dew point temperature in order to avoid condensation.
Application
  • Hardener: 612-000B (regular), 612-001B.
  • Mix 4 parts by volume of A and 1 part by volume of B.

IMPORTANT: Mix mechanically in order to obtain a homogeneous product

METHOD:

  • Gun.
  • Electrostatic version on certain colours only.
  • Paint brush for touch up.

For conventional equipment:

  • Reduce the material with thinner to a viscosity of 20-25 sec FC#4 before applying.
  • Pressure at gun should be approximately 40-50 PSI and 10-15 PSI in pressure tank.

 

For "airless" equipment:

  • Reduce the material with thinner to a viscosity of 25-35 sec FC#4 before applying
Precaution
  • Do not leave the paint in the hose, guns and pump. The equipment has to be well cleaned with Sunamco cleaning thinner Sunaclean 100-113.
  • For a better adhesion a light sanding is required when product is thoroughly dry.
  • Make sure you complete the profile sandblasting in order to avoid surface rust caused by an angular profile.

TEST:

Due to the wide variety of substrates, surface preparation methods, application methods, and environment, users should test the complete system for adhesion and compatibility under their conditions prior to starting their production.

N.B. To make adhesion, hardness, flexibility, impact test, or any other test, it is recommended to wait 7 daysat 25ºC (68ºF) and 50% humidity to enable the chemical reaction to be completed. If conditions are not fits outlined, the reaction time could be longer.

Restrictions
  • Do not apply at temperatures below 10oC or 50o F otherwise drying and the hardness will be affected.
  • As with most epoxy coatings, when there is no topcoat, the series 612 may chalk or discolour when exposed to ultraviolet outside light.  On the other hand this does not affect the anticorrosive properties of this product.
Caution

This product is intended for use only by professional applicators in industrial situations in accordance with the advice given on this sheet, the Material Safety Data Sheet and the container(s) and should not be used without reference to the Material Safety Data Sheet (MSDS).

All work involving the application and use of this product should be performed in compliance with all relevant national Health, Safety & Environmental standards and regulations.

In the event welding or flame cutting is performed on metal coated with this product, dust and fumes will be emitted which will require the use of appropriate personal protective equipment and adequate local exhaust ventilation.

If in doubt regarding the suitability of use of this product, consult Société Chimique Sunamco Inc. for further advice.
