540 Polyurethane

540 Polyurethane is a two-pack acrylic modified urethane topcoat.

Hydroxy functional acrylic resins are designed to cross-link at room temperature with polyisocyanates. Resistant films are quickly formed avoiding the necessity of providing stoving facilities. It also allows the end user to coat articles which are too big to be stoved, or which are sensitive to heat. These high performance coatings are suitable for a wide range of applications.

Features:

• Excellent durability
• Excellent gloss and colour retention
• Recoatable with minimum surface preparation
• Tough finish with good chemical resistance.
• Non-yellowing coating.

Typical areas of application are:

• Implements and farm machinery.
• Forklifts, tankers and trucks.
• Chemical and petroleum industry.
• Industrial and mining equipment.

Surface Preparation:

• When overcoating; Aged paint coatings should be tested for adhesion using
  Crosshatch or Crosscut methods. If aged paint coating lifts remove it.
• Remove all rust, oxides, millscale and lose paint from metal surface.
• Round off all sharp edges, welding joints and weld spatter.
• All surfaces to be painted should be clean and free from dust, dirt, oil, grease and
  moisture.
• All abrasive blast clean ferrous surfaces should be coated within 4 hours to avoid flash
  rusting.
• Do not apply at temperatures below 5’ Celsius. Do not apply at relative humidity above
  85%, or when the substrate surface is less than 3’ Celsius above dew point.

Application:

• Mix 540 “Part A” equal parts with 540 “Part B” (Ratio 4:1). Allow to stand for 10
  minutes, then stir again before using.
• Brush or Roller – Thinning not normally required.
• Conventional Spray – Thin approximately 20% and apply 2 coats wet on wet.
• Airless Spray – Thin approximately 5 – 10% and apply.
• Clean Up – T154 or T134 All Purpose Thinner.
