Em-Poxy WB - Water-Based Epoxy Primer

Description
It is a double-component, epoxy and water based, easy-to-clean undercoating material with humidity tolerance and resistant to some chemicals.
Usage Areas
It is used as an undercoat on concrete, metal, wood, asphalt, etc. before the application of polyurethane coatings and epoxy-based top coating systems.
Surface Preparation
• Pressure strength of the concrete to be treated must be 25 N/mm2 minimum and tensile strength 1,5 N/mm2 minimum.
• The surface to be treated must be clean and dry and free from any other substance such as dirt, grease, old coatings and curing materials.
• Gaps and holes must be completely cleared first and then filled with Em-Poxy A which is prepared in paste form by adding sand.
• To ensure a smooth surface any swelling must be levelled.
• All dust and loose and displaced particles must be removed by using a brush and/or vacuum cleaner.
• During application relative humidity must not exceed 50% when the ambient temperature is +10°C, and 80% when the ambient temperature is +30°C.
• The temperature of the surface to be treated must be between +10°C and +30°C.
• The temperature of the surface to be treated must be 3°Chigher than the dew point.
• Ambient temperature and surface temperature must be increased by using heaters for the applications performedin cold weather conditions and Em-Poxy A containers must be kept under +20°C the previous night.
Application
First, Component A is mixed to a homogenous consistency in its orijinal packaging using a low speed mixer for approximately 1 minute and then Component B is added into it to continue mixing for approximately 3 minutes again with the low speed mixer.
The application should be performed with a roller or brush. The mixture can be applied within approximately 40 minutes
depending on the air temperature. The surface treated must be protected fron water for 4-5 hours. For perfect adhesion the concrete surface should be a little humid and it will be sufficient to wipe the surface with a damp cloth. As the undercoat completes its cure, the application of the top coat must be performed within minimum 12 and maximum 18 hours.
Consumption
0,150 kg/m2 for a single coat. Depending on the absorbance of the surface to be treated the application of a second coat may be required.
Packaging
5 kg (Component A) + 5 kg (Component B) = Net 10 kg as a set
