Sika Poxicolor® Primer HE NEW
2-pack primer coat based on epoxy resin. Economically and high-performance corrosion protection also for manually de-rusted surfaces and surfaces prepared by high-pressure water jetting. Low solvent content according to Protective Coatings Directive of German Paint Industry Association (VdL-RL 04).
- Surface tolerant
- High layer thickness and diffusion resistance combined with very good surface wetting properties and adhesion result in a very high safety margin for good corrosion protection
- Fast initial drying and full hardening
- High-build application
- Very economically due to high coverage
Usage
Tough hard, versatile overcoatable primer for corrosion protection on steel exposed to atmosphere. Especially suitable for use on surfaces where only manually de-rusting (wirebrushing or power tool cleaning) or high-pressure water jetting is feasible or economic.Advantages

SURFACE PREPARATION
Steel:
The durability of corrosion protection by coatings generally depends on the surface preparation. Usually, blasting is the most effective and economical solution.
For permanent immersion and permanent condensation, we recommend to prepare the surfaces in accordance with ISO 12944-4 Sa 2 ½. In case of atmospheric exposure hand- or power-tool cleaning in accordance with St 2 is sufficient. Even ultra high pressure water jetting according to ISO 8501-4 Wa 2 with a maximum flash rust grade M is also acceptable.
Note: Sika Poxicolor® Primer HE NEW is not recommended for continuous immersion. In addition, the surface must be dry, free of dirt, oil, grease and loose rust.
Hot dip galvanized surfaces:
Free from oil, grease and zinc salts.
In case of permanent condensation surfaces should be sweep blasted according to ISO 12944-4.
Old coatings:
In case of well adhering coating systems, careful cleaning(e.g. by water jetting) is sufficient. Loose particles must be removed, damaged areas should be minimum de-rusted in accordance with PSa 2, PMa or PSt 2 and primed with Sika Poxicolor® Primer HE NEW.
The required surface preparation/cleaning and compatibility of the system should be determined with trial areas.
Contaminated surfaces e.g. galvanized surfaces, primed areas or old coatings 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:
- Surface preparation St 2 or St 3
- With brush application best penetration and surface wetting is achieved
Conventional high pressure spraying:
- Nozzle size 1.7 - 2.5 mm
- Pressure 3 - 5 bar
Airless-spraying:
- Pressure of 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°
