Technical Information

CURE MECHANISM

Sikasil® Marine cures by reaction with atmospheric moisture. The reaction starts at the surface and proceeds to the core of the joint. The curing speed depends on the relative humidity and the temperature. At low temperatures the water content of the air is lower and the curing reaction proceeds more slowly.

Application

Application Information

Surface preparation

Surfaces must be clean, dry and free from oil, grease and dust.
Sika® Remover-208 or another suitable solvent may be used for cleaning.

Application

To minimise smearing of surfaces with excess sealant, masking tape can first be applied to surrounding surfaces.

Cut the nozzle to the desired bead size then apply a continuous bead as required. For bonding, apply bead to only one surface. For sealing, push the sealant into the joint as it is being applied to ensure good wet out onto the surface.

Assemble parts and/or tool off any excess sealant before it skins over, then immediately remove any masking tape.

For more information, please contact the Technical Service Department of Sika Industry.

Removal

Uncured, excess Sikasil® Marine may be removed with Sika® Remover- 208 or another suitable solvent. Cured sealant can only be trimmed away or scraped off mechanically.

Hands and exposed skin should be washed immediately using SikaCleaner®- 350H or a suitable industrial hand cleaner and water.

Do not use solvents!

 

Overpainting

Sikasil® Marine cannot be overpainted. If a similar but overpaintable product is required, consider using Sikaflex®-291 marine adhesive sealant.

Application limits

Sikasil® Marine is not recommended for use on:
- below waterline applications (except as a mechanically compressed gasket seal)
- sealing joints subject to heavy traffic (e.g. deck caulking)
- pre-stressed polycarbonate or other plastic surfaces that are prone to stress cracking

Joints deeper than 15 mm should be avoided.

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