Sherwin-Williams Transgard TG111V2

Sherwin-Williams Transgard TG111V2 is a high build 2-pack epoxy zinc phosphate primer/buildcoat, designed as anti-corrosive protection of carbon steel surfaces prepared by abrasive blast cleaning.

Transgard TG111V2 can be applied at thicknesses between 75 and 150 microns dry to provide both primer and buildcoat in a single coat. A topcoat is only required for decorative purposes. Without a topcoat, the material will quickly discolour and patchiness may be exaggerated due to film thickness variation, but the coating will nonetheless provide excellent anti-corrosive protection as a single coat protective epoxy and the intercoat adhesion will not be affected by any discolouration.

Recommended Topcoats

For overcoating with epoxy products (including self overcoating), the maximum recommended interval is 28 days at 23°C. For overcoating outside this interval, consult Sherwin-Williams technical support for advice.

Where a high degree of gloss and colour retention is required, overcoat with Acrolon C137V2 or Transgard TG169 within 7 days at a minimum d.f.t. of 50 microns. These overcoating times refer to achievement of optimum adhesion at 23°C and will vary with temperature.

For overcoating outside the above parameters, consult Technical Team for advice. 

Surface Preparation

Blast clean to Sa21⁄2 BS EN ISO 8501-1:2007). Average surface profile in the range 50-75 microns.

Manually prepared surfaces should be prepared to a minimum standard of St3 ISO 8501-1:2007 at the time of coating.

Ensure surfaces to be coated are clean, dry and free from all surface contamination.

May also be applied over a wide range of pre-fabrication primers, including inorganic zinc silicate, and epoxy types.
