Surface preparation

The performance of this product will depend upon the degree of surface prepraration.  The surface to be coated must be clean and free of from contamnation.  Prior to paint application all surfaces should be assessed and treated in accordance with ISO 8504:2000.  Accumulated dirt and soluble salts must be removed.  Dry bristle will normally be adequate for accumulated dirt.  Soluble salts should be removed by fresh water.  Oil or grease should be removed in accordance with SSPC-Sp1 solvent cleaning.

Abrasive blast cleaning
Abrasive blast clean to SSPC-SP6 or Sa 2½ (ISO 8501:2007).  If oxidation has occurred between blasting and application of SUNAPRIME 603, the surface should be reblasted.  Surface defects revealed by the blast cleaning process should be ground, filled or treated in the appropriate manner.

Manual or mechanical preparation
Mannually or mechanically blast until minimum standard ST3 (ISO 8501:2007) is obtained or SSPC-SP3 for atmospheric use only.  Note:  It is necessary to remove all scales.  Areas that can't be prepared adequately by chipping or needle hammer, should be blasted locally with abrasive jet until standard Sa 2 (ISO 8501-2007) or SSPC-SP6 is obtained.Typically, this standard could be applied to corrosion grades C or D.

Application
  • Hardener: 603-000B (regular) & 603-001B (anti-sagg)
  • Mix 3 parts by volume of A and 1 part by volume of B.

IMPORTANT: Mix mechanically in order to obtain a homogeneous product

METHOD:

  • Conventional air vaporisation
  • Airless vaporisation, air assisted, air mix.
  • Electrostatic version (contact your representative).
  • Paint brush for hardly accessible places

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.

Consult your local sales representative for information about the application.

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 drying time exceeding 24 hours we recommend a light sanding for a better inter-coat adhesion.
  • 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 days at 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 603 line 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 ofr 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.
