Shelf life and storage::
- Shelf-life: 12 months from production date in case of stored properly in unopened original packaging.
- Storage conditions: Dry conditions at tem- perature between +5°C and +30°C.
Component A: Resin
Component B: Hardener
- Recommended dry film thickness:
- 250 μm (in several layers) for normal conditions.
- 500 μm (in several layers) for severe conditions. - Do not apply webershield 146 on substrates in which significant vapor pressure may occur.
- Stability in vertical surface: < 300 μm (wet film thickness).
- Freshly applied webershield 146 must be protected from damp, condensation and water for at least 24 hours.
- Avoid puddles on applied surface.
- The incorrect assessment and treatment of cracks may lead to a reduced service life and reflective cracking.
- For exact colour matching, ensure webershield 146 is applied from the same control batch numbers.
Pot-life:
Temperature | Time |
|---|---|
10oC | ~90 mins |
20oC | ~60 mins |
30oC | ~30 mins |
- *All technical data stated in this Product Data Sheet are based on laboratory tests. Actual measured data may vary due to circumstances beyond our control.
- Waiting time/overcoat ability: in case of coats up to 150 μm dry film thickness
Substrate temperature | Minimum | Maximum |
10oC | 30 hours | 3 days |
20oC | 10 hours | 2 days |
30oC | 6 hours | 1 days |
Notes: Times are approximate and will be affected by changing ambient conditions. If these waiting times cannot be observed inter-coat adhesion problems must be expected and activation will have to be carried out. The best activation method is by light grinding /blasting and followed by thorough de-dusting prior to apply of the next coat.
