Endorsements

  • Complies with BS4652:1995 (amended 1998).

Recommended Primers & Topcoats

Indefinitely overcoatable with epoxy systems provided a minimum of 50 microns dft is obtained. Do not overcoat with paints containing saponifiable resins such as oleo-resinous or alkyd based paints unless a non-saponifiable resin based barrier coat has been applied first.

Surface Preparation

Blast clean to Sa21⁄2 BS EN ISO 8501-1:2007. Average surface profile in the range 30-75 microns.

Ensure surfaces to be coated are dry and free from all visible traces of surface contaminants.

For repair of galvanizing, for small areas, abrade the surface to a minimum standard of St3 per BS EN ISO 8501-1:2007, feathering off the edges of intact galvanizing surrounding such areas, and then brush apply the primer. For large areas it is recommended that the surface is flash blasted and the primer applied by the desired method. 

Application Equipment

Airless Spray

Nozzle Size: 0.38mm (15 thou) 
Fan Angle: 40°
Operating Pressure: 115kg/cm² (1600 psi)

The airless spray details given above are intended as a guide only. Details such as fluid hose length and diameter, paint temperature and job shape and size all have an effect on the spray tip and operating pressure chosen. However, the operating pressure should be the lowest possible consistent with satisfactory atomisation. As conditions will vary from job to job, it is the applicators’ responsibility to ensure that the equipment in use has been set up to give the best results. If in doubt Sherwin-Williams should be consulted.

Nozzle Size

Environmental legislation now requires paint to contain less solvent. When using high solids coatings like Epigrip J984BS Zinc Rich Primer painters must use finer spray tips than previously to compensate for the natural tendency towards over-application and to help achieve good wet film formation.

Brush

The material is suitable for brush application to small areas and for touch up purposes. Application of more than one coat may be necessary to give equivalent dry film thickness to a single spray applied coat. 

Application Conditions & Overcoating

This material should preferably be applied at temperatures in excess of 10oC. In conditions of high relative humidity, ie 80-85% good ventilation conditions are essential. Substrate temperature shall be at least 3oC above the dew point.

At application temperatures below 10°C, drying and curing times will be significantly extended, and spraying characteristics may be impaired.

Application at temperatures below 5°C is not recommended. In order to achieve optimum water and chemical resistance, temperature needs to be maintained above 10oC during curing.

If it is desired to overcoat outside the times stated on the data sheet, please seek advice of Sherwin-Williams.

Additional Notes

Drying times, curing times and pot life should be considered as a guide only.

The curing reaction of epoxies commences immediately the two components are mixed, and since the reaction is dependent on temperature, the curing time and pot life will be approximately halved by a 10°C increase in temperature and doubled by a 10°C decrease in temperature.

Exposure to Weathering

If Zinc Clad J984BS is exposed to the weather, there is a risk of the formation of zinc salts on the surface, which must be removed by flash blasting or washing down prior to overcoating, otherwise intercoat adhesion my be adversely affected.

The rate of zinc salt formation will vary from one location
to another. Under severe conditions e.g. marine coastal, offshore or heavy industrial areas, it is strongly recommended that overcoating takes place within 7 days.

Epoxy Coatings - Tropical Use

Epoxy paints at the time of mixing should not exceed a temperature of 35oC. Use of these products outside of the pot life may result in inferior adhesion properties even if the materials appear fit for application. Thinning the mixed product will not alleviate this problem.

The maximum air and substrate temperature for application is 50°C providing conditions allow satisfactory application and film formation. If the air and substrate temperature exceed 50°C and epoxy coatings are applied under these conditions, paint film defects such as dry spray, bubbling and pinholing etc, can occur within the coating.

Numerical values quoted for physical data may vary slightly from batch to batch.
