Application Information

Mixing Ratio 

Part A : Part B = 100 : 34,5 by weight

Ambient Air Temperature 

+15 °C min. / +40 °C max.

Dew Point 

Beware of condensation.
The substrate and uncured applied resin must be at least +3 °C above dew point to reduce the risk of condensation or blooming on the resin surface.

Substrate Temperature 

+15 °C min. / +40 °C max.

 

  

Substrate Moisture Content 

≤ 4 % parts by weight

The following test methods can be used: Sika-Tramex meter,
CM-measurement or Oven-dry-method. No rising moisture according to ASTM (Polyethylene-sheet).

Pot Life 

TemperaturePot-lifeOpen time
+15 °C~3 hours~6 hours
+23 °C-~4 hours
+40 °C~60 minutes~90 minutes

The pot-life begins when Parts A+B are mixed. It is shorter at high temperatures and longer at low temperatures. The greater the quantity mixed, the shorter the pot-life. To obtain longer workability at high temperatures, the mixed adhesive may be divided into smaller quantities. Another method is to chill Parts A+B before mixing (although not below +5 °C).
