Plasmet Z–GALV
Product reference: 5/28
Product title: Plasmet Z-GALV
Valid from: 21st December 2009
Last reviewed: July 2019
Type: A surface tolerant two-pack epoxy coating compound incorporating a rust inhibitor and passivator, with good adhesive properties to galvanised surfaces.
Suggested use
Plasmet Z-Galv is manufactured to give good corrosion protection on rusted metals with minimum surface preparation, it may also be applied to UHP water-blasted or grit-blasted surfaces as an inhibitive coating or primer. Z-Galv can be used entirely on its own, in single or multiple coats or can be overcoated with other Plasmet coatings to give a smoother, more easily cleaned and chemically resistant surface. Plasmet Z-Galv is tough, durable and tolerant of vehicular traffic. It can be used for protection in both atmospheric and immersed conditions. In atmospheric conditions Z-Galv may be used under decorative finishes such as polyurethane or enamel. Plasmet Z-Galv is particularly effective on fresh and weathered galvanised surfaces.
Limitations
Not suitable for immersion in strong acidic or alkaline environments unless overcoated
Health & Safety
WARNING: When using this product safety precautions should be observed. Avoid contact with skin or eyes, do not ingest. Protective clothing and goggles should be worn. Ensure good ventilation and wear a vapor mask suitable for hydrocarbon vapors. When using in confined spaces an airfed mask should be worn. Read safety data sheet before use.

Application
Plasmet Z-Galv should be applied thin enough to avoid runs or sags in the coating at a wet film thickness of approximately 10 mils (250 microns). Z– Galv should not be applied to surfaces at temperatures below 39°F (4°C). This material will tolerate high humidity conditions during application but the surface temperature should be at least 37°F (3°C) above dew point.
Thinners
A blended thinner may be obtained from Corrocoat where thinning is necessary and may be used to thin Z-Galv to a maximum of 10%.
Packaging
1 Gallon and 5 Gallon kits
Storage life
2 years minimum in unopened tins, stored at 41-104°F (5-40°C).
Activator type
Polyamide (Plasmet Z-Galv Activator).
Temperature resistance
Approximately 140°F (60°C) immersed; up to 203°F (95°C) immersed when over-coated with a suitable top coat.266°F (130°C) non-immersed.
Dry / cure time
Cure time will vary dependent upon temperature but will be approximately 30 hours at 39°F (4°C); 18 hours at 68°F (20°C), 10 hours at 266°F (30°C).
Surface preparation
Remove oil, grease and any other surface contaminants utilizing a suitable solvent, detergent cleaner or emulsifier.Z-Galv will tolerate damp surfaces but excess moisture mustbe removed, dry is best. Most existing firmly bonded coatings can be tolerated and overcoated by PlasmetZ-Galv.
Application equipment
Brush and roller, or airless spray equipment using a 45:1 ratio or greater pump and gun fitted with a 19 to 25 thou tip of reversible type.
Mixing ratio / mixing
7:1 base to activator by weight. Remove lids from both components A-Activator and B-Base and pour all of component ‘A’ into component ‘B’ and mix thoroughly. Ensure that no unmixed material remains, the material is now ready for use and should be applied as soon as possible. After mixing, the material remains usable for a limited period dependent upon temperature, after which timeapplication becomes difficult. A small amount of Plasmet Z-Galv thinner floated on top of the material will aid brush application in hot climates
Pot life
At 68°F (20°C), 1.5 hours for brush/roller application or 50minutes for spray application.
Color availability
Grey, black, oxide red, dark green.
Recommended DFT
Dependent on service duty, but generally one coat at 6 mils (150 microns) in light atmospheric duty; two coats at 6 mils (150 microns) in aggressive atmospheric or immersed conditions. Edge and stripe coating will be required witheither single or double coats. Z-Galv may be used at 5 mils (120 microns) as a primer for other topcoats and paints
Practical spreading rate
130 sf per gal at 6 mils (3.2 m²/litre at 150 micron dft) Note: This information is given in good faith but may increase dependent upon environmental conditions, the geometry and nature of work undertaken and the skill and care of application. Corrocoat accepts no responsibility for any deviation from this value.
