Storage Conditions
The product must be stored in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +5 °C and +30 °C. Always refer to packaging.
Density
~1,08 kg/l (+20 °C)
Volatile organic compound (VOC) content
| VOC-CH | 18 % |
| VOC-EU | 18 % |
Consistency
Viscous liquid
Application
Ambient Air Temperature
+5 °C min
Substrate Temperature
+2 °C min. No frost
Setting Time
~20 minutes at +20 °C. At the minimum application temperature and low relative humidity the setting time can be prolonged.
Hardening time ~1–5 hours. Final strength is achieved after ~1 week. All these times can be affected by ambient conditions.
Consumption
~200 g/m2 to 300 g/m2 for partial bonding.
Consumption depends on the roughness and absorbency of the substrate.
These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc.
SUBSTRATE QUALITY
The substrate must offer sufficient strength and adhesion to resist the forces generated by wind suction.
SUBSTRATE PREPARATION
The substrate must be firm, clean, dry or slightly moist, free from oil, grease, dust, stripping agents, standing water, bitumen residue and loose friable particles.
APPLICATION
Reference must be made to further documentation where applicable, such as relevant method statement, application manual and installation or working instructions.
Application Method
Position and align the membrane. Apply even strips of Sika® Trocal C-300 adhesive directly out of the container or by using an adhesive dispenser cart with a bead diameter of 8–10 mm.
Moisten the adhesive strips slightly with a fine mist of water, ideally using a backpack sprayer with a double-nozzle lance. Using a rubber spatula, evenly spread the adhesive strips to create a thin adhesive film. The membrane is then rolled immediately into the wet adhesive. Press down firmly on the membrane using a suitable pressure roller.
Only apply the adhesive on the immediate membrane installation area. When completed apply adhesive onto the next area.
Rate of adhesive application for moderate wind loads < 2,4 kN/m2
