1 July 2011 Page 1 of 2 LI 002 METALSHIELD cold galv Primer One Pack Zinc Rich Primer LI 002 FEATURES ZINC RICH SINGLE PACK FAST DRYING SURFACE TOLERANT TOUCHUP SPRAYPAKS AVAILABLE USES METALSHIELD cold galv Primer incorporates a high level of finely divided zinc in the dry film providing sacrificial protection to steel substrates with the convenience of single pack application. It is excellent for the repair of damaged galvanised steel and wrought iron balustrades and railings. SPECIFICATIONS Type 1 RESISTANCE GUIDE HEAT RESISTANCE WEATHERABILITY SOLVENTS ACIDS Up to 65 C dry heat. On exterior exposure some chalking may also occur. This will not detract from the protective properties of the coating.

2 Use a weatherable topcoat if required for appearance. Resistant to splash and spillage of aliphatic hydrocarbons only. Not recommended for acid conditions. ALKALIS SALTS WATER ABRASION Not recommended for use in highly alkaline conditions. Unaffected by splash and spillage of neutral salt solutions only. Resists rain and condensation. Not recommended for permanently damp or immersed exposure. Good when fully cured.

4 TYPICAL SPREADING RATE AT RECOMMENDED DRY FILM BUILD A spreading rate of sq. metres per litre corresponds to 75 microns dry film thickness assuming no losses. Practical spreading rates will vary depending on such factors as method and conditions of application and surface roughness.

It is recommended that the specific needs of a project be discussed with a Dulux Protective Coatings Consultant.) SURFACE PREPARATION GUIDE SYSTEM DRY FILM THICKNESS GALVANISED (Repair of) Clean, degrease and abrade surface 1st Coat METALSHIELD cold galv Primer 75 Microns SURFACE PREPARATION Steel: Round off all rough welds, sharp edges and remove weld spatter.

5 Remove grease, oil and other contaminants in accordance with Rust, millscale, oxide deposits and old paint films on metal surfaces must be removed by abrasive blast cleaning to Class (ISO 8501-1:Sa ). Remove all dust by brushing or vacuum cleaning. Galvanised Steel (Repair of): Round off all rough welds, sharp edges and remove weld spatter. Remove grease, oil and other contaminants in accordance with Rust, millscale, oxide deposits and old paint films on metal surfaces should be removed by hand or power tool ( St 3) cleaning as a minimum. Coating performance is proportional to the degree of surface preparation and abrasive blast cleaning to a minimum Class 2 is preferred for more severe environments.

6 Remove all dust by brushing or vacuum cleaning. APPLICATION Stir each can thoroughly until the contents are uniform. Use of a power mixer is recommended. Remix thoroughly before using and continue mixing during application. BRUSH/ROLLER For small areas only. Apply even coats of the mixed material to the prepared surface. When brushing and rolling additional coats may be required to attain the specified thickness. Thin required with up to 100 ml/litre with METALSHIELD cold galv Thinner (965-H0012) to ease application. CONVENTIONAL SPRAY Thin up to 200 ml/litre with METALSHIELD cold galv Thinner (965-H0012) to aid atomisation. Ensure paint is regularly agitated during application to prevent separation. Typical Set-up Graco Delta Gun: Pressure at Pot: Pressure at Gun: (239543) 70-100 kPa (10-15 ) 380-410 kPa (55-60 ) TOUCHUP SPRAYPAKS For all application instructions and properties of the Touchup Spraypaks refer to the details located on the back of the aerosol can.

7 Note a slight colour variation may be experienced compared to the standard product due to film build, application methods and technique. AIRLESS SPRAY Standard airless spray equipment such as a Graco 33:1 Bulldog or 45:1 Xtreme with a fluid tip of 19-21 thou ( ) and an air supply capable of delivering 550-690 kPa (80-100 ) at the pump. Ensure paint is regularly agitated during application to prevent separation. Thinning is not normally required but up to 60 ml/litre of METALSHIELD cold galv Thinner (965-H0012) may be added to ease application. PRECAUTIONS This is an industrial product designed for use by experienced Protective Coating applicators. Where conditions may require variation from the recommendations on this Product Data Sheet contact your nearest Dulux representative for advice prior to painting.

8 Do not apply in conditions outside the parameters stated in this document without the express written consent of Dulux Australia. Do not apply at temperatures below 5 C. Do not apply at relative humidity above 85% or when the surface is less than 3 C above the dewpoint. Do not apply on structures subject to sustained surface temperatures above 65 C or where spillage of solvent may occur. Do not weld or flame cut through chlorinated rubber coatings. Due to their thermoplastic nature, chlorinated rubber coatings are more suited to on site application. If transporting shortly after application care should be taken to ensure painted surfaces are not in contact. Topcoats of a saponifiable nature such as alkyds must never be applied directly to METALSHIELD cold galv Primer .

9 CLEAN UP Clean all equipment with METALSHIELD cold galv Thinner (965-H0012) immediately after use. OVERCOATING Aged coating should be tested for lifting by a method appropriate for the coating thickness, for example X cut or cross-hatch methods. If it lifts, remove it. The surface must be free of oil, grease and other contaminants. High-pressure water wash at to MPa (1,200 - 1,500 ) to remove loosely adhering chalk and dust. SAFETY PRECAUTIONS Read Data Sheet, Safety Data Sheet and any precautionary labels on containers. 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.

10 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 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.
