SikaCor® EG-5

2-pack AY-PUR top coat

SikaCor® EG-5 is a 2-pack acrylic polyurethane top coat. By adding 1 % b.w. SikaCor® PUR Accelerator (see product data sheet for more information) a fast touch and through drying will be achieved.

Combined with 2-pack epoxy primer and intermediate coats:
  • Very good corrosion protection properties
  • Excellent chemical, weather and colour stability
  • Tough elastic and hard but not brittle
  • Largely insensitive against shock and impact

Usage

In combination with 2-pack primer and intermediate coats of the SikaCor® and Sika® Permacor® product range for heavy duty corrosion protection of atmospheric exposed and submerged steel structures. SikaCor® EG-5 can also be used as a line marking paint on selflevelling and broadcasted epoxy and polyurethan resin based floors.  

Advantages

Combined with 2-pack epoxy primer and intermediate coats:
  • Very good corrosion protection properties
  • Excellent chemical, weather and colour stability
  • Tough elastic and hard but not brittle
  • Largely insensitive against shock and impact

Application steps

SURFACE PREPARATION

Steel: Blast cleaning to Sa 2 ½ according to ISO 12944-4. Free from dirt, oil and grease. Hot dip galvanized steel, stainless steel and aluminium: Free from dirt, oil, grease and corrosion products. In case of permanent immersion and condensation the surfaces must be slightly sweep blasted with non-ferrous abrasives. For contaminated surfaces e.g. galvanized or primed areas we recommend to clean with SikaCor® Wash.

MIXING

Stir component A very thoroughly using an electric mixer (start slowly, then increase up to approx. 300 rpm). Add component B carefully and mix both components very thoroughly (including sides and bottom of the container). Mix for at least 3 minutes until a homogeneous mixture is achieved. Fill mixed material into clean container and mix again shortly as described above. During mixing and handling of the materials always wear protective goggles, suitable gloves and other protective clothings.

APPLICATION

The method of application has a major effect on achieving uniform thickness and appearance. Spray application will give the best results. The indicated dry film thickness is easily achieved by airless spray. Adding solvents reduces the sag resistance and the dry film thickness. In case of application by roller or brush, additional applications may become necessary to achieve the required coating thickness, depending on type of construction, site conditions, colour shade etc. Prior to major coating operations a test application on site may be useful to ensure the selected application method will provide the requested results.

 

By brush and roller Conventional high pressure spraying:

  • Nozzle size 1.5–2.5 mm
  • Pressure 3–5 bar
  • Oil and water trap is compulsory

Airless-spraying:

  • Pressure min. 180 bar
  • Nozzle size 0.38–0.53 mm (0.015–0.021 inch)
  • Spraying angle 40°–80°

CLEANING OF TOOLS

SikaCor® Cleaner

Spraying equipment must be rinsed with Sika® Thinner EG before using SikaCor® EG-5.
