Application Information Mixing Ratio Part A:B = 2:1 parts by weight or volume Product Temperature +10 °C min. / +30 °C max. Ambient Air Temperature +10 °C min. / +30 °C max. Dew Point Beware of condensation.
Steel substrate temperature during application must be at least +3 °C above dew point. Substrate Temperature +10 °C min. / +30 °C max. Substrate Moisture Content Cementitious substrates:
Substrate must be dry or matt damp (no standing water).
Brush the adhesive well into the substrate if matt damp. Pot Life | Temperature | Pot life | Open time | | +10 °C | ~125 minutes | – | | +23 °C | ~50 minutes | ~70 minutes | | +30 °C | ~25 minutes | – |
If larger quantities are being mixed the temperature of Sikadur-Combiflex CF Adhesive Normal will increase due to the chemical reaction, resulting in a reduced pot life. Waiting Time / Overcoating Sikadur-Combiflex CF Adhesive Normal may be overcoated with an epoxy coating. If this is required, do not smooth the adhesive with detergent. If waiting time between application of adhesive and overcoating is to be longer than 2 days, the adhesive must be blinded to excess with quartz sand immediately after application. |
