Technical Information

CURE MECHANISM

The curing of SikaPower®-2955 takes place by chemical reaction of the 2 components.

It cures at ambient temperature. The curing speed can be accelerated by temperature (max. up to 60 °C) using infrared laps or ovens, e. g. 10 °C higher temperatures would result in approx. doubling the curing speed and cutting in half the open time.

Application

Application Information

Surface preparation

Abrade surfaces with 80 – 180 grit sanding paper. Clean and degrease the surfaces before applying SikaPower®-2900 Primer. Additional surface treatment depends on the specific nature of the substrates.

Application

Detailed work instruction for plastic repair can be found in the Plastic Repair Guide.

The below information is offered for general guidance only. Advice on specific applications will be given on request.

Extrude adhesive without mixer to equalize the filling levels, attach the mixer and dispose of the first few cm of the bead.

SikaPower®-2955 has to be processed between 10 °C and 30 °C (product, ambient, and substrate temperature).

Dispense SikaPower®-2955 with adequate piston guns. In order to achieve a proper mixing, Mixer Tips for SikaPower®-2900 Series (part of packaging and sold separately) are required.

 

Removal

Uncured SikaPower®-2955 can be removed from tools and equipment with Sika® Remover-208 or another suitable solvent. Once cured, the material can only be removed mechanically.

Hands and exposed skin have to be washed immediately using hand wipes such as Sika® Cleaner-350H or a suitable industrial hand cleaner and water.

Do not use solvents on skin.
