Description

High gloss, two pack siloxane coating for protection of primed steel (including inorganic zinc silicate coatings), non ferrous metals or concrete.

  • For shop or site application.
  • Suitable for new construction, repair or maintenance.
  • Excellent adhesion, colour and gloss retention. Abrasion resistant, isocyanate free cosmetic finish.
  • Resistant to atmospheric exposure, including marine environments. Suitable for use in environments C1–C5 (to ISO 12944) with suitable primer.
  • Full colour range.
  • Superior colour and gloss retention compared with polyurethane finish coats. Offers optimum cosmetic performance.

Compliance:

  • ACQPA.
  • ISO 12944 (class C5M).
  • Norsok M – 501 system 1.

Preparation:

  • May be applied to many types of soundly adhered existing coating. Consult manufacturer.
  • Primed surface must be clean, dry, undamaged and free from all contaminants, including salt deposits. Round off rough welds and remove weld spatter.
  • Optional tie coat.
  • Product is supplied as two packs in correct proportions for use. Add cure to resin.
  • Application: Airless or conventional spray or roller.
  • One or two coats. Requirement may vary with method of application, characteristics of substrate and hiding power of selected colour.
  • Thickness to recommendation of PPG, dependant on context. Recommended maximum dry paint thickness: 250 µm.
  • Air temperature 0–50ºC. Surface temperature 0–65ºC. Temperature must exceed dew point by 3ºC.
  • Ensure double coating at welds, rough spots, sharp edges and corners, rivets and bolts.
  • Drying times vary with environmental conditions. Indicative: At 20ºC a coat can be touch dry in two hours, dry through in 4.5 hours.
  • Check coating thickness using non destructive dry film thickness metre, e.g. Mikrotest or Elcometer.

Overcoating:

Recoatable in three hours
