HEMPEL SILIC ONE Biocide-Free Antifouling
SVB item number: 50412
Manufacturer no.: 151228
SILIC ONE, a fantastic 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.

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.

Easy switching from biocide-containing antifouling to SILIC ONE
here's how:
Existing coating
If you want to switch to the biocide-free SILIC ONE from HEMPEL, you don't have to go to the trouble of removing your existing underwater coating. With the help of the 2-K Conversion Primer, it is easy to switch from conventional antifouling to advanced biocide-free fouling protection.
If the existing antifouling is still in good condition with good adhesion, the primer can simply be applied with a brush or roller. Stir the base, add the hardener and mix well (ratio 3:1). One full and undiluted coat is sufficient to achieve excellent adhesion. It is then recommended to apply a coat of TIECOAT. When applying SILIC ONE for the first time, two coats should be applied. For all following applications one layer is sufficient. The boat can be launched after 30 hours. Maximum downtime before taking to water is one month.
If adhesion is poor, please remove all flaking and brittle coating components. Sand them down with damp sandpaper. Rinse the whole thing thoroughly with fresh water and follow the instructions for ‘’new set up‘’.
New setup
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 one coat of TIECOAT. 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. Maximum downtime before taking to water is one month.
Note!
Biocide-free antifouling is a green alternative to chemical antifouling. Unlike biocide-containing antifoulings, biocide-free antifouling does not kill marine organisms such as algae and mussels, but makes it more difficult for growth to adhere. Regular cleaning of the hull is necessary to ensure that biocide-free antifoulings can effectively prevent fouling to take hold. The use of biocide-free antifoulings is advisable in waters with low or medium fouling levels, for example in freshwater or cooler waters.

Technical question
Jonathan S.
| Aug 31, 2021
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.
