Application
Mixing Ratio
Component A : Component B = 4 : 1 by weight
When using bulk material, the exact mixing ratio must be safeguarded by accurately weighing and dosing each component.
Ambient Air Temperature
+10 °C min. / +35 °C max.
Dew Point
Beware of condensation.
Substrate temperature during application must be at least 3 °C above dew point.
Substrate Temperature
+10 °C min. / +35 °C max.
Substrate Moisture Content
< 4 % pbw
Pot Life
| Temperature | Pot-life | Open time |
| +10 °C | ~90 minutes (5 kg) | ~90 minutes |
| +23 °C | ~60 minutes (5 kg) | ~60 minutes |
| +35 °C | ~30 minutes (5 kg) | ~30 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 (although not below +5 °C).
Consumption
See the "Method Statement for SikaWrap® manual dry application" Ref. 850 41 02.
Guide: 0.7 - 1.5 kg/m2.
SUBSTRATE QUALITY
Substrate must be sound and of sufficient tensile strength to provide a minimum pull off strength of 1.0 N/mm2 or as per the requirements of the design specification.
See also the "Method Statement for SikaWrap® manual dry application" Ref. 850 41 02.
SUBSTRATE PREPARATION
See the "Method Statement for SikaWrap® manual dry application" Ref. 850 41 02.
MIXING
Pre-batched units:
Mix components A+B together for at least 3 minutes with a mixing spindle attached to a slow speed electric drill (maximum 300 rpm) until the material becomes smooth in consistency and a uniform grey colour. Avoid aeration while mixing. Then, pour the whole mix into a clean container and stir again for approximately 1 more minute at low speed to keep air entrapment at a minimum. Mix only that quantity which can be used within its pot-life.
Bulk packing, not pre-batched:
First, stir each component thoroughly. Add the components in the correct proportions into a suitable mixing pail and stir correctly using an electric low speed mixer as above for pre-batched units.
CLEANING OF TOOLS
Clean all equipment immediately with Sika® Thinner C. Cured material can only be removed mechanically.
