ADDITIONAL NOTES

Mixing Instructions: Thoroughly agitate Binder Part E using low speed continuous air driven agitation. Slowly mix all of Zinc Dust Part F into all of Binder Part E until mixture is completely uniform.

After mixing, pour mixture through 30-60 mesh screen. Mixed material must be used within 8 hours. Do not mix previously mixed material with new. If reducer solvent is used, add only after both components have been thoroughly mixed. Continuous agitation of mixture during application is required, otherwise zinc dust will quickly settle out.

Do not tint.

Excessive fi lm build, poor ventilation, and cool temperatures may cause solvent entrapment and premature coating failure.

Any salting on the zinc surface due to weathering exposure must be removed prior to topcoating.

An intermediate coat is recommended to provide uniform appear-ance of the topcoat.

Oil base, alkyd, epoxy ester, and silicone alkyd topcoats are not recommended.

Topcoats may be applied once 50 MEK double rubs are achieved.

No zinc or only slight traces should be visible. Coin hardness test can also be used.

ADDITIONAL NOTES

Tint Part A with GIC colorants at 150% strength. Five minutes minimum mixing on a mechanical shaker is required for complete mixing of color.

Tinting is not recommended for immersion service.

Can be used as a metalizing sealer. Consult your Sherwin-Williams Representative regarding Product Bullentin: "Sealers for Thermal Spray Metalizing".

Quick-Kick Epoxy Accelerator is acceptable for use. See data page for details.

Acceptable for concrete fl oors.

Application to surfaces above 120°F (49°C) is not recommended in VOC Restricted Areas (≤250 g/L). When spraying a surface above 120°F (49°C) in other areas (>250 g/L), please consult with your Sherwin-Williams representative. Spray apply only. Product will produce an orange peel appearance when applied at elevated temperatures.

Topcoating: It is recommended to apply a thinned-down, low wet fi lm thickness mist coat over zinc rich primers to help avoid outgassing.

Allow it to tack up and seal the surface. Then apply a full wet fi lm thickness coat as directed.

Mix contents of each component thoroughly with low speed power agitation. Make certain no pigment remains on the bottom of the can. Then combine one part by volume of Part A with one part by volume of Part B. Thoroughly agitate the mixture with power agita-tion. Allow the material to sweat-in as indicated prior to application.

Re-stir before using.
