Sika® Permacor®-2230 VHS
Sika® Permacor®-2230 VHS is a 2-pack Acrylic-Polyurethane topcoat, with extremely low solvent content and with very good optical and mechanical properties. Low solvent content according to Protective Coatings Directive of German Paint Industry Association(VdL-RL 04). Suitable for use in hot and tropical climatic conditions.
- Excellent weather resistance due to high gloss and colour retention
- Fast curing characteristics, short recoating time
- Economical due to high volume solids
- VOC-value of approximately 250 g/l
Usage
Sika® Permacor®-2230 VHS is used as mechanically resistant top coat for atmospheric exposed steel surfaces for example bridges, pipelines, industrial and harbour installations, tanks, wind power stations as well as sewage treatment plants and steel structures in common. Together in combination with 2-pack primers and intermediate coats of SikaCor® and Sika® Permacor® results in mechanically resistant coating systems for long life corrosion protection with extremely high weather resistance up to corrosivity category C5-M high, according to ISO 12944-2.Advantages
- Excellent weather resistance due to high gloss and colour retention
- Fast curing characteristics, short recoating time
- Economical due to high volume solids
- VOC-value of approximately 250 g/l

SURFACE PREPARATION
Steel:Blast cleaning to Sa 2 ½ according to ISO 12944, part 4.Free from dirt, oil and grease.Galvanized steel, stainless steel and aluminium:Free from dirt, oil, grease and corrosion products.In case of condensation the surfaces must be slightly sweep blasted with a ferrite-free blasting abrasive.For contaminated surfaces e.g. galvanized or primed areas we recommend to clean with SikaCor® Wash.
MIXING
Stir component A thoroughly using an electric mixer (start slowly, then increase up to approximately 300 rpm). Add component B carefully and mix both components thoroughly (including sides and bottom of the container). Mix for at least 3 minutes until a homogeneous mixture is achieved. Pour mixed material into clean container and mix again shortly as described above.
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.
Airless-spraying:
- Pressure minimum 150 bar
- Nozzle size 0.38 - 0.53 mm (0.015 - 0.021 inch)
- Spraying angle 40 ° - 80 °
