ZINCANODE® 402

Two Pack Zinc Rich Epoxy Primer PC 122

FEATURES • ECONOMICAL ZINC RICH EPOXY
• RAPID DRY AND OVERCOAT TIMES
• EASY TO TOPCOAT WITH EPOXIES, POLYURETHANES, AND CHLORINATED RUBBERS
• SUITABLE FOR USE IN ENVIRONMENTS UP TO 200°C
• PROVIDES EXCELLENT CORROSION PROTECTION
USES ZINCANODE® 402 is a two-pack epoxy zinc rich primer formulated for exceptional cathodic corrosion resistance
in harsh corrosive environments. ZINCANODE® 402 is recommended for use over abrasive blast cleaned steel
surfaces, especially where overcoating is required without special mist or seal coat techniques.
ZINCANODE® 402 offers ease of application, high film builds without mud-cracking and exceptional adhesion to
field weld areas cleaned by power sanding or power wire brushing. It is specified for use in power generation
plants, bulk handling equipment and oil refineries. Also in mining and chemical processes, offshore structures and
exposed pipelines.

SPECIFICATIONS Approved to APAS 2916 AS/NZS 3750-9 Type 2

RESISTANCE GUIDE
WEATHERABILITY Epoxy coatings yellow with time and chalk on SOLVENTS Good resistance to splash and spillage
exterior exposure. Neither yellowing nor of aromatic and aliphatic hydrocarbon
chalking detracts from the protective solvents and alcohols
properties of the coating. Use a weatherable
topcoat if required for appearance.
HEAT RESISTANCE Up to 200°C dry heat WATER Excellent resistance to and salt water
when suitably topcoated
SALTS Excellent resistance to neutral and alkaline ALKALIS Not recommended for alkaline
salts when suitably topcoated conditions unless suitably topcoated
ACIDS Not recommended for acid conditions ABRASION Very good when fully cured

SURFACE Steel: Round off all rough welds, sharp edges and remove weld spatter. Remove grease, oil and other
PREPARATION contaminants in accordance with AS1627.1. Degrease with Gamlen CA 1 (a free-rinsing, alkaline detergent)
according to the manufacturer’s written instructions and all safety warnings. Abrasive blast clean to a minimum of
AS1627.4 Class 2.5 with a blast profile of 40 – 70 microns. Remove all dust brushing or vacuum.
APPLICATION Mix each can thoroughly using a power mixer until the contents are uniform. Mix the contents of both packs together
thoroughly with a power mixer and let stand for 10 minutes. Ensure clean-up solvent (Dulux® Epoxy Thinner) is
available. Remix thoroughly before and during application
BRUSH/ROLLER For small areas only. Apply even coats of the mixed material to the prepared surface. Thinning is not normally
required, however, up to 50 ml/litre of Dulux® Epoxy Thinner (920-08925) can be added to aid application. When
brushing and rolling additional coats may be required to attain the specified thickness.
CONVENTIONAL Thinning is not normally required, however, up to 50ml/litre of Dulux® Epoxy Thinner (920-08925) can be added
SPRAY to ease application. Ensure paint is regularly agitated during application to prevent settling.
Typical Set-up Graco AirPro: 1.8mm (239543)
Pressure at Triton 308: 70-105 kPa (10-15 p.s.i.)
Pressure at Gun: 380-415 kPa (55-60 p.s.i.)
AIRLESS SPRAY Standard airless spray equipment such as a Graco Xtreme 45:1 with a fluid tip of 15-17 thou (0.38-0.43mm) and
an air supply capable of delivering 550-690 kPa (80-100 p.s.i.) at the pump. Ensure paint is regularly agitated
during application to prevent settling. Thinning is not normally required but up to 50 ml/litre of Dulux® Epoxy Thinner
(920-08925) may be added to aid application
PRECAUTIONS This is an industrial product designed for use by experienced Protective Coating applicators. Ensure that you read
and understand the safety precautions on the relevant Material Safety Data Sheets before using. The surface to
be coated must be totally free of moisture and contaminants. Do not apply at temperatures below 10°C. Do not
apply at relative humidity above 85% or when the surface is less than 3°C above the dewpoint. The rate of cure is
dependent upon temperature. Where application conditions are outside the parameters stated in this Product Data
Sheet, or where any variation to the recommendations within this document are sought, contact your Dulux®
Consultant for written consent or specifications prior to application. Freshly mixed material must not be added to
previously mixed material. DO NOT apply coatings of a saponifiable nature such as alkyds directly to this zinc rich
product.
CLEAN UP Clean all equipment with Dulux® Epoxy Thinner (920-08925) immediately after use.
OVERCOATING Degrease with Gamlen CA 1 according to the data sheet. Test adhesion of existing coating by standard cross hatch
adhesion test. If the coating fails, remove it. High-pressure water wash at 8.3 to 10.3 MPa (1,200-1,500 p.s.i.) to remove
chalk and dust. Abrade surface to provide a good key for the new coating. Epoxies must be abraded if recoated outside
the recoat window.
SAFETY Read Data Sheet, SAFETY DATA SHEET and any precautions on container labels. SAFETY DATA SHEET
PRECAUTIONS is available from Customer Service (13 23 77) or www.duluxprotectivecoatings.com.au
STORAGE Store as required for a flammable liquid Class 3 in a bunded area under cover. Store in well-ventilated area away from
sources of heat or ignition. Keep containers closed at all times. Contents of container may be under pressure.
HANDLING As with any chemical, ingestion, inhalation and prolonged or repeated skin contact should be avoided by good occupational
work practice. Eye protection approved to AS1337 should be worn where there is a risk of splashes entering the eyes.
Always wash hands before smoking, eating, drinking or using the toilet.
USING Contents of container may be under pressure. Containers should be carefully opened by first placing a rag, then a hand,
over the lid then gently easing the lid off. Use with good ventilation and avoid inhalation of spray mists and fumes. If risk
of inhalation of spray mists exists, wear combined organic vapour/particulate respirator. When spraying, users must comply
with their respective State Spray Painting Regulations.
FLAMMABILITY This product is flammable. All sources of ignition must be eliminated in, or near the working area. DO NOT SMOKE. Fight
fire with foam, CO2 or dry chemical powder. On burning will emit toxic fumes.
WELDING Avoid inhalation of fumes if welding surfaces coated with this paint. Grind off coating before welding.
