Axalta ViterShield 178 HS Epoxy Primer/Finish is a two-pack epoxy, high solids, zinc phosphate primer or primer/finish for steelwork. High performance, low VOC coating to help meet SED requirements.

Axalta ViterShield 178 HS Epoxy Primer/Finish has exceptional sag resistance, as well as excellent cure speed and high build properties. It is overcoatable with most epoxy, acrylic or polyurethane coatings and can be used as a base coat for most thin film intumescent coatings.

Product Specification

Film Thickness Range And Coverage

Drying Times

Surface Preparation

• Blast clean to Sa2½ (ISO 8501-1:2007), surface profile 50-75 microns
• All surfaces to be coated should be dry and cleaned as necessary to remove all oil, grease, salts, weld flux or other contamination. Where necessary, remove weld spatter and grind smooth all sharp edges and weld seams

Mixing

Mixing Ratio:

• Base 6178 - 5 parts by volume
• Hardener 6400 003 - 1 part by volume

Notes:

• Mix only in the proportions stated, mixing each component individually then together using a mechanical agitator
• Agitate periodically during use to ensure product remains homogeneous

Thinner

Thinner

• Axalta 1031 Thinner

Equipment Cleaner

• Axalta 950 Thinner

Application Conditions

• Only apply in conditions of good ventilation which must be maintained during drying and curing
• Do not apply when rain, mist, sleet or snow are imminent
• During application and drying time of the paint coating, the surface should be dry, the relative humidity should not exceed 85% and the steel temperature should remain at least 3°C above the dew point
• Only apply this product when the above conditions can be maintained throughout the critical application and drying/curing process
• Paint temperature should ideally be at a minimum of 15ºC

Application Methods

• Airless Spray: Output fluid pressure at tip 2200 psi, Tip Size: 13 thou (0.33mm) for dft’s 75-125um; 15-17 thou (0.38-0.43mm) for 125-280um
• Thinning of the coating will reduce the build qualities
• Application by brush/roller will result in a reduced film thickness and is recommended only for small areas of touch up/remedial work
• Refer to Axalta Coating Systems ‘Epoxy Application and Curing Notes’

Product Notes

• May be overcoated with itself or other products from the ViterShield, ViterSeal or ViterThane range
• If overcoating with ViterThane PLV or PLS, allow a minimum of 12 hours at 23°C when the primer has been applied to 100 microns dft. Allow longer drying and overcoating times at higher dft’s and lower temperatures
• The compatibility of overcoating should be confirmed prior to application
• Certain configurations of steelwork may mean that the primer will have to be applied in more than one coat to achieve the higher film thicknesses
• Whilst this product will display a matt finish at a dry film thickness of 75 microns, application to a dry film thickness above 125 microns will provide a low sheen finish, the degree of which may vary
• Do not apply or cure below 5°C, temperatures above 10°C recommended
• Like all epoxy coatings, this product will chalk on prolonged exterior exposure, the degree of which is subject to atmospheric conditions

Health & Safety

• Containers are provided with safety labels which should be observed
• Further information about hazardous influences and protection are detailed in individual Product Safety Data Sheets
