Maximum | +55 °C |
Substrate Moisture Content
Max. 4 % pbw

Pot Life
Temperature | Pot life | Open time |
+25 °C | 90 minutes | 120 minutes |
+55 °C | 30 minutes | 60 minutes |
The pot life begins when the resin and hardener 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 portions. Another method is to chill components A+B before mixing them (not below +5 °C).
Squeezability

MIXING
PRE-BATCHED UNITS
- IMPORTANT Mix full units only. Prior to mixing all parts, mix part A (resin) briefly using a mixing spindle attached to a slow-speed electric mixer (max. 300 rpm).
- Add part A to part B (hardener) and mix parts A+B continuously for at least 3 minutes until a uniformly coloured, smooth consistency mix has been achieved.
- IMPORTANT Do not overmix. To ensure thorough mixing, pour materials into a clean container and mix again for approximately 1 minute. Mixing time for A+B = 4 minutes.
