A two-component, fast reacting injection resin
WILLFLEX®09 is a two-component, fast-reacting phenolic foam system, for use in mining and tunneling for fast and efficient backfilling of larger and smaller cavities.
The product is suitable for:
- filling of larger and smaller cavities
- building fire protection dams
- sealing of weather dams
- avoidance of CH 4 - accumulation, avoidance of explosion danger by methane gas
The system use with different mixing ratio can causes the reaction time changes and mechanical strength changes.
|Compressive strength||20 kPa|
|Foam factor||> 40|
|Mixing ratio A : B||4 : 1|
|TDS & MSDS on request|
It is intensively mixed volumetrically in a ratio of 4: 1 ( A-comp. : B-comp.) via a static mixer and the mixed product is either freely discharged as an instant foaming product into the cavity to be filled or injected via injection lances or self-drilling anchors into the cavity to be filled. Immediately after mixing the two components, the product forms an instant foam, i.e. it has no liquid phase but immediately forms a stable foam that can be built up very easily. This makes the time-consuming erection of shuttering largely unnecessary. The reacted product is stable with a low compressive strength (> 20 kPa), but it reliably prevents further expansion of the cavity in question.
