Description

Sherwin-Williams Macropoxy M330 (formerly known as M330) is a 2-pack epoxy sealercoat for use over zinc silicate and other types of zinc rich primers. It is also used as a blast primer for use over stainless steel.

Recommended Primers & Topcoats

  • Zinc Clad J984 Zinc Rich Primer
  • Dox-Anode D5V2

Indefinitely overcoatable with epoxy systems provided the surfaces to be coated have been suitably cleaned. Where a high degree of gloss and colour retention is required, overcoat with Acrolon C137V2, Acrolon C237 within 7 days at a minimum dft of 50 microns or in the case of Accrolon C750V2 overcoat within 4 days. These overcoating times refer to achievement of optimum adhesion at 23°C and will vary with temperature.

For overcoating with alkyd systems consult Technical Team for advice. 

Application Conditions & Overcoating

Epoxy paints 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 and always above 0°C.

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

Application at ambient air 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 from Technical Team.

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.

When M330 is used as a tie-coat or sealer coat over inorganic zinc silicate, the zinc silicate must be left for a minimum of 16 hours at 15°C and then checked for cure. Prior to overcoating, the inorganic zinc silicate primer must be fully cured.

Care must be taken to ensure that Macropoxy M330 is not over-applied on to the zinc silicate otherwise there is a possibility of pinholing occurring. 

Epoxy Coatings - Tropical Use

Epoxy paints at the time of mixing should not exceed a temperature of 35°C. At this temperature the pot life will be approximately halved. 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 temperatures 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.
