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 layer of TIECOAT
. Using 2-K Conversion Primer makes it even easier to migrate from conventional antifouling to SILIC ONE, as Conversion Primer can be applied to previous antifoulings if they are in good condition. When applying SILIC ONE for the first time, two coats should be applied. 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.

Absolutely top - my verdict after one season
The amount of work in March this year was enormous. We have a 44-year-old Janneau 28 on Lake Chiemsee and have decided to completely rebuild the underwater hull. Removed the old antifouling with the scraper blade, sanded, filled epoxy, sanded, applied 5x Hempels Light Primer, then 1x Silic one Tiecoat and then 2x Silic one. Between the penultimate light primer coat and the subsequent coats, the max and min times must be observed depending on the temperature. In March, this can only be carried out in a heated hall. Time spent for two is two long weekends of 4 days each. Now to the conclusion The first aha effect came during the season. Our boat runs significantly faster. Especially with the typical light winds on Lake Chiemsee, we amazed many a performance boat. And now after the season and the crane out, the result is still sensational. A light cleaning of the underwater hull with the high-pressure cleaner and the paint looks like new. The time and money were worth it and we are finally setting an example when it comes to the environment.

Good performance, price a bit too high
The product is really good. There is nothing to complain about, only the delivery service is. Unfortunately, that's the case everywhere at the moment. It would be nice if the gentlemen were only paid when the service was rendered, then things would probably go differently.

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.
