Application

Application Information

Mixing Ratio

Component A : component B = 100 : 34.5 by weight
When using bulk material the exact mixing ratio must be safeguarded by accurately weighing and dosing each component.

Ambient Air Temperature

+15 °C min. / +40 °C max.

Dew Point

Beware of condensation.
Substrate temperature during application must be at least 3 °C above dew point.

Substrate Temperature

+15 °C min. / +40 °C max.

Substrate Moisture Content

< 4 % pbw

The potlife 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 potlife. 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).

Application steps

SUBSTRATE QUALITY

The 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 wet application" Ref 850 41 03 and the "Method Statement for SikaWrap® saturator machine wet application" Ref 850 41 04.

SUBSTRATE PREPARATION

See the "Method Statement for SikaWrap® manual wet application" Ref 850 41 03 and the "Method Statement for SikaWrap® saturator machine wet application" Ref 850 41 04.

MIXING

Pre-batched units:
Mix components A+B together for at least 3 minutes at low speed. 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.
Bulk packing, not pre-batched:
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® Colma Cleaner. Cured material can only be removed mechanically.
