Product details

Discover HEMPEL's latest innovation and technological excellence
SILIC ONE, a biocide-free product based on silicone and hydrogel, gives the surface water-like properties. This means that organisms that cause fouling can no longer settle as easily on the hull and will quickly drop off as soon as the boat is in motion. It is suitable for both fast motor boats as well as sailboats.
Other impressive benefits also include the ease with which any fouling can be removed and with which the coating may be reapplied. This leads to long-term cost savings.
  • Can be used on all surfaces, except wood.
  • Creates a non-stick surface
  • Biocide-Free
  • Copper-free

What is hydrogel?
Hydrogel is based on unique, non-reactive polymers, that are added to the paint and form an invisible protective layer between the hull surface and the water. Vegetation forming organisms perceive the hull as a liquid and therefore are a lot less likely to stick to it.

Processing instructions

Technical specifications
  • Application temperature: +10 °C (surface temperature must be above the dew point)
  • Drying time at 20 °C: 3 hours (dry to touch)
  • Overcoating time at 20 °C: 16 hours

Suitable for vessels made of GRP and steel.
To ensure optimum adhesion of the SILIC ONE, the hull's surface has to be primed first. Use LIGHT PRIMER to do this. Then apply a coat of HEMPEL TIECOAT.
Using SILIC SEAL, a 2-component epoxy primer makes it even easier to migrate from conventional antifoulings to SILIC ONE, as SILIC SEAL can be applied to previous antifoulings if they are in good condition.
When applying SILIC ONE for the first time, two layers are the minimum. For all following applications one layer is sufficient. After 24 hours, the boat can be launched. The maximum time span until launching should be no more than one month.

Auch nach 2 Jahren mit Winterlager noch Top
Contrary to the manufacturer's recommendation, despite winter storage, I do not paint a new layer after a few weeks of land storage and the protection against solid growth remains excellent. Use SilicOne on a GFK-15 dinghy cruiser on the Havel. After 1 week, a light algae coating forms on the underwater hull, which after a few hours of sailing only remains in the area of the waterline. However, this can easily be removed with a rag. At the end of the season, wipe it off with a wet wipe and you have a shiny underwater ship! In between the boat lay idle for a maximum of 7 weeks, the dark slime with a few algae simply falls off after a few meters of travel. In the past, there were often mussels in the untreated sword case, after I treated them with SilicOne in the underwater area as well. Has survived 200 km of trailers and 4 times cranes without damage. For possible repairs, small amounts can simply be drawn up from the freshly opened jar with a syringe, placed in a small, dry disposable glass and a few pearls of desiccant such as molecular sieve or silica gel added. Absolute recommendation for those who do not want to paint antifouling every winter, pay attention to good upholstery (cushions) when trailers and want to bring a little less copper into our waters.

Super Service
First a praise to SVB, I called on Monday because I was missing a can of silicon one. I needed the product in Enkhuizen (NL) because the boat should be in the water on Friday. The DHL messenger was on site punctually on Thursday. Big cinema. We are very satisfied with silicon one. We first used it two years ago. After this time in the water, the hull was like new. We have rebuilt some places (Kiel) and painted them with a different color on the previous one. Red on blue so that in two years we can see exactly where we need to rework. I have a suggestion for improvement. The boat rests on stamps and must be painted in these places before entering the water. A whole can is way too much for that, a quarter of a can, for this use, it would be easy.

After two years of the first order, our conclusion - it works great! We have a Cruiser 40 in the IJsselmeer, brackish water. We had completely rebuilt the hull with four new layers of epoxy and tiecoat primer. Please note the processing time and maximum time intervals. After two years, with the high-pressure cleaning, at a distance !, the underwater hull was like new and freshly painted. There were so many astonished looks in the harbor. A thin streak has come off with the palm of your hand! Great thing! There were few small spots where the Silic One, smaller than a fingernail, came off. It is possible that too little primer was applied or the paint was too thin - unfortunately we don't know. After two years we have now applied a coat of paint with short pile rollers. You have to work quickly, preferably in pairs. For our 40s, including the keel and rudder blade, we got along with exactly 5 cans. B. when it goes into the water. We have chosen a different color in order to be able to recognize the layer application, we can only recommend that.

Technical question

Flag of English Hi, I recently bought enough silicone to do the drive components of my ribs outdrive and also my shafts and propellors on my own boat. I spent 12 hours preparing all surfaces, priming, tie coating and paining on the fouling. Both boats cruise at 24 to 28knots and after putting 30 hours on my 18 tonne 15m boat at about 20 knots we dived to find no silicone left on the props and rudders. This is very disappointing as I was using this as a test to do the entire boat hull next year. Can you think of any reason the product would be this way on my big boat but working well in the rib? I there just too much pressure on it when applied to a larger boat? Thanks #50413#

I am not shure for the aplication of silic one to the props and the rudders. I have only used it on the hull of the boat and I find it perfect. As long you do not physicali demage the antifuoling it is very good at any speeds I have traveled (up to 36 knots). A friend of mine has had it for three years now and it looks like new.
