Sika Poxicolor® Rapid

Low solvent containing, fast-curing epoxy resin coating for steel

Sika Poxicolor® Rapid is a chemically and mechanically resistant high solid 2-pack epoxy primer and intermediate coat containing zinc phosphate as an active pigment.
Low solvent content acc. to Protective Coatings Directive of German Paint Industry Association (VdL-RL 04).

  • Short overcoating times, up to 3 coats per day
  • Fast curing at low temperatures
  • Suitable as sealer for thermal-sprayed metallic coatings
  • Very economical due to low solvent contents

Usage

Durable corrosion protection for steel constructions exposed to water, salt water or domestic waste water, up to corrosivity category C5 high acc. to ISO 12944-2.
Sika Poxicolor® Rapid can also be used as sealer for thermal-sprayed metallic coatings to close pores and also as a subsequent intermediate coat.  

Advantages

  • Short overcoating times, up to 3 coats per day
  • Fast curing at low temperatures
  • Suitable as sealer for thermal-sprayed metallic coatings
  • Very economical due to low solvent contents

Higher layer thicknesses, but also lower temperatures as well as lower air humidity than specified, lead to longer drying times. The overcoating intervals can be delayed and may need to be determined on site.
Max.: 1 year
In case of longer waiting times please contact us.

Prior to further applications: After a waiting period or after exposure to weathering, all possible contamination must be removed from the surface before the subsequent coating is applied.

Note, if using as a sealer: Pre-spray the thinned Sika Poxicolor® Rapid thinly onto the thermal-sprayed metallic coat and after a waiting time of approx. 15 minutes, spray ‘wet on wet’ the missing layer thickness of Sika Poxicolor® Rapid.

Thinner

Sika® Thinner EG
Adapt the viscosity: If necessary add max. 5% Sika® Thinner EG.

If used as a sealer: Thinn with 20 % Sika® Thinner EG. Use the heavily diluted material immediately and under continuous stirring.

Drying time

Final drying time
Depending on layer thickness and temperature final hardness is achieved within 5 - 7 days.

Application steps

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


Airless-spraying:

  • Pressure min. 180 bar
  • Diameter of hoses min. 10 mm (⅜ inch)
  • Nozzle size 0.38 - 0.53 mm (0.015 - 0.021 inch)
  • Spraying angle 40° - 80°
