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. |
