Dekalin and Dekasil

Dekalin has many products in use that have been used for decades in the manufacturer and aftermarket and have proven themselves. Sika has some newer products (approx. 3 years old) that have been developed as an alternative to Dekasyl products. Dekalin has a wider range of products to recommend the best solution for each application.

There is a whole range of Dekalin products for caravans and motorhomes that are suitable for different applications

Dekasyl products for bonding and sealing, Dekaseal products for sealing only.

In general:
Bonding: Dekasyl MS-2, MS-5, MS-5, MS-8
Sealing: Dekasyl MS-1, MS-6, MS-7
There is no clear boundary between adhesives and sealants. All Dekasyl products can be used for both bonding and sealing.

Dekaseal and Dekasyl products can be removed (when fresh) with e.g. Dekaclean Ultra. Dekaseal 8936 can be dabbed off by itself.

Dekasyl MS products can be painted over. The best results can be achieved when recoating within 4 hours.
If recoating is to take place after more than 24 hours, it is advisable to apply a primer beforehand.

All Dekasyl MS products and Dekaseal 1512

Dekaseal 8936 can be dabbed off immediately after application.

Dekaseal 8936 is a better product than SikaLastomer 710: It has a higher viscosity, is very easy and quick to blot and has a lower water vapor permeability.

Dekaseal 8936 is only for applications where mechanical fasteners (such as screws) are also used. Examples: Service hatch, lights, socket, skylight etc.

Dekaseal 1512 can be used as a general sealant. It can be used, for example, for skylights, hole penetrations in the floor, general sealing in the floor or for placing side walls on the floor.

Depending on the application: with e.g. screws Dekaseal 8936 is the ideal solution. For sealing without screws Dekaseal 1512 should be used (or a Dekasyl product),

Dekaseal 8936 is a wipe-on sealant based on so-called polyisobutene (similar to butyl). Polyisobutene-based sealants have the lowest water vapor permeability and are therefore excellent for sealing structures that are also mechanically fastened and for preventing water leaks.

Dekaseal 8936 can be removed immediately after application. However, it is recommended to wait 1-2 hours because more solvent will have reducer. It dries only by evaporation of the solvent. If you wait a little, it will also pull fewer wires. It is also good to let it dry in the air.
However, the vehicle can be moved again immediately after applying Dekaseal.

At least 2 years

Dekaseal 8936 can be dabbed off for applications that are also mechanically attached in the visible area, e.g. side panels. It is advisable to first cut or push with a plastic card or knife next to the application so that no Dekaseal is removed from under the joint when dabbing.

For a 40x40 roof window you need about 220 ml Dekaseal. Care should be taken to use enough Dekaseal. In addition, the part should be squeezed out after use to ensure that it is completely sealed and watertight.
