Dekalin DEKASYL MS-6 black 310 ml - highly elastic MS polymer sealant and adhesive for plastics, bathrooms and joints in motorhomes
- Soft, highly elastic MS polymer sealant with primerless adhesion to ABS, PC, PMMA, GRP, aluminium and glass. Mould resistant, elongation approx. 600%, 310 ml.
Dekalin DEKASYL MS-6 is a universal, highly elastic MS polymer sealant and adhesive with low hardness (Shore A approx. 32) and elongation at break of about 600%. The manufacturer designed it for the materials used by motorhome and caravan builders, to which it adheres without special pre-treatment, including spare parts such as painted side walls, plastic parts and metals. Due to its high elasticity, MS-6 is mainly a sealant, but it can also bond where no high forces are transferred. The product has received the PLUS X AWARD.
Key features
- Elongation at break approx. 600%, the joint absorbs large material movements
- Primerless adhesion to ABS, PC, PMMA, GRP, aluminium, stainless steel and glass
- Mould resistant, suitable for bathroom and wet-area joints
- Long working time: skin after approx. 30 minutes
- Free of solvents, isocyanates, silicone and PVC, low odour
Use in motorhomes and caravans
In motorhomes and caravans DEKASYL MS-6 is used for elastic sealing of connection joints at windows, doors, roofs and floors, joints in the bathroom and shower, and for bonding and sealing spoilers. The manufacturer calls it a problem solver for difficult-to-bond surfaces, so it is a good choice for repairs on parts made of different plastics.
If the joint has to bond strongly, for example when fitting solar panels or profiles, choose DEKASYL MS-5 or MS-2. MS-6 is best where a soft, highly elastic and neat joint matters.
DEKASYL adhesives and sealants are not a replacement for a plastic sealant under the flanges of roof lights, side windows and service doors that will have to be removed later. For such places the manufacturer specifies the non-curing DEKASEAL 8936.
How to use, step by step
- Clean and degrease both surfaces with DEKACLEAN Ultra or a DEKACLEAN Ultra cloth and let it flash off for about 3 minutes.
- On plastics and difficult surfaces apply a thin coat of DEKAVATOR 22 NF activator and wait about 5 minutes.
- Cut the cartridge tip, trim the nozzle at an angle to the required bead width and apply the compound with a manual or pneumatic gun at +5 to +35 °C.
- For bonding, join the parts within about 35 minutes of application (20 °C, 50% relative humidity) and press them lightly if needed.
- For sealing, tool the joint within about 30 minutes with a spatula wetted with DEKAFINISHER. Do not let the agent get under the compound, as this reduces adhesion.
- The compound cures with moisture from the air. It reaches full strength after a few days, depending on layer thickness, temperature and humidity.

How to choose the right product
The DEKASYL range includes several MS polymer compounds that differ in hardness, elasticity and bond strength. The overview below is based on the manufacturer technical data sheets; the highlighted row is the product on this page.
| Product | Main job | Shore A hardness | Elongation at break | Skin time approx. | Service temperature |
|---|---|---|---|---|---|
| DEKASYL MS-1 | universal joint sealing and light bonding | 52 | 300% | 10 min | -40 / +100 °C |
| DEKASYL MS-2 | bonding and sealing with higher strength | 55 | 250% | 10 min | -40 / +100 °C |
| DEKASYL MS-5 | structural bonding: solar panels, SAT systems, spoilers | 55 | 210% | 12 min | -40 / +120 °C |
| DEKASYL MS-6 | soft, highly elastic joint on plastics | 32 | 600% | 30 min | -40 / +90 °C |
| DEKASYL MS-7 | transparent bonding and sealing | 40 | 250% | 35 min | -40 / +100 °C |
| DEKASYL MS-8 | windscreen bonding, drive-away time approx. 60 min | 58 | 300% | 10 min | -40 / +100 °C |
Safety at work
- Labelling according to the safety data sheet (version of 29.01.2024): EUH208: Contains a sensitising substance. May produce an allergic reaction. EUH210: Safety data sheet available on request.
- Read the label and the safety data sheet before use. Work in a well-ventilated area, wear protective gloves and, when working overhead, safety glasses.
- Keep out of reach of children. Dispose of residues and packaging in line with local regulations; do not pour into drains.
Storage and shelf life
Store in the tightly closed original packaging in a cool, dry place, protected from frost and direct sunlight. The best-before date is printed on the pack. Close an opened cartridge tightly and use it up soon, because the compound in the nozzle cures with moisture.

Frequently asked questions
Is MS-6 suitable for a shower cubicle?
Yes. The manufacturer states mould resistance and intends MS-6 for elastic joints in sanitary areas.
Do I need a primer on plastics?
On ABS, PC, PMMA, GRP, aluminium, stainless steel and glass MS-6 adheres without primer. On unusual plastics run a test and use DEKAVATOR 22 NF activator if needed.
How long do I have to tool the joint?
A skin forms after about 30 minutes (20 °C, 50% humidity), so there is plenty of time to smooth the joint with DEKAFINISHER.
