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) | ~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 (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 (max. 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 approx. 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 EQUIPMENT
Clean all equipment immediately with Sika® Colma Cleaner. Cured material can only be removed mechanically.
