Description and uses:

605 Zinc Rich Primer is a two-pack inorganic zinc which provided cathodic protection to
steel. The main features are:

• Resist topcoat pin-holing.
• Easy application by brush, roll or spray.
• Good solvent resistance.
• Provides excellent corrosion protection.

Typical areas of application are:

• Bridges and steel fabrications.
• Chemical process industries and refineries.
• Fertilizer plants.

Technical Specifications:

FINISH: Matt Grey.
THINNERS: T180.
VOLUME SOLIDS: 64% (mixed).
VOC: 415 gms/litre (mixed).
COVERAGE: 8.0 – 9.0 Square metres per litre (at a D.F.T. of 75 microns).
RECOMMENDED FILM THICKNESS: 50 – 100 microns.
APPLICATION: Conventional, Airless Spray Brush or Roller.
DRYING AT 25’C / 50% Humidity:

• Touch dry: 1 hour.
• Recoat Minimum: 1 – 2 hours
• Hard dry: 2 – 3 hours

Surface Preparation:

• When overcoating; Aged paint coatings should be tested for adhesion using Crosshatch or Crosscut methods. If aged paint coating lifts remove it.
• Remove all rust, oxides, millscale and lose paint from metal surface.
• Round off all sharp edges, welding joints and weld spatter.
• All surfaces to be painted should be clean and free from dust, dirt, oil, grease and moisture.
• All abrasive blast clean ferrous surfaces should be coated within 4 hours to avoid flash rusting.
• Do not apply at temperatures below 5’ Celsius. Do not apply at relative humidity above 85%, or when the substrate surface is less than 3’ Celsius above dewpoint.
• Applied 605 Zinc Rich Primer coat subjected to exterior exposure for extended period of time should be accessed for “Chalking” before applying suitable topcoat to achieve optimum intercoat adhesion.

Equipment Application: (Conventional or Airless Spray Recommended). As a Guide Use:

• Brush or Roller – Suitable for touch ups and repairs to small areas only.
• Conventional Spray – 1.5 -2.0mm tip (or equivalent). Pressure pot set at 55 – 100kpa (8 – 15psi) and maintain gun air pressure 275 – 380kpa (40 -55psi).
• Airless Spray – Use heavy-duty airless spray with 10 -15 “(0.25 – 0.38mm) plus tip and pump ratio 30:1.
