Application Information Mixing Ratio | Part A : Part B | 1 : 2 by weight or volume |
* It is essential that both components are fully used, ensuring no excess material remains within the container prior to mixing. Failure to do so could adversely affect the chemical reaction. Sag Flow Non-sag up to 1 mm thickness on vertical surfaces | (EN 1799) |

Dew Point Beware of condensation. Steel substrate temperature during application must be at least +3 °C above dew point. Substrate Temperature Maximum | +30 °C | Minimum | +10 °C |
Pot Life | Temperature | Pot Life (200g) | | +10 °C | ~120 min | | +23 °C | ~45 min | | +30 °C | ~35 min |
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 +10 °C). Open Time | Temperature | Open Time | | +10 °C | ~150 min | | +23 °C | ~90 min | | +30 °C | ~60 min |
