HEMPEL SILIC ONE TIECOAT

The SILIC ONE developed by HEMPEL is a copper- and biocide-free fouling release coating system based on silicone and hydrogel. Due to its special surface properties, it makes it more difficult for fouling-forming organisms to adhere and also makes their removal easier when moving through the water or by manual cleaning by hand. Suitable for fresh, salt, and brackish water as well as for inland waters. Particularly recommended in areas where biocides may not be used or may only be used to a limited extent (including in the Netherlands). Suitable for plywood, GRP, steel, or aluminum hulls, for fast motorboats as well as sailboats.How it works: Polymers contained in the coating react with water at the surface and form an invisible protective layer, a so-called hydrogel between the hull surface and the water. For microorganisms, this layer is perceived as a liquid, so that they do not settle on the hull in the first place. The micro-rough structure and the smooth surface tension also prevent a firm anchoring of fouling-forming organisms, so that they fall off again through manual cleaning or when traveling quickly through the water.Application: With the help of HEMPEL CONVERSION PRIMER, SILIC ONE can also be applied to existing antifouling coatings (in good condition). For this, one coat of CONVERSION PRIMER and then one coat of TIECOAT are applied. For a new coating, priming with HEMPEL LIGHT PRIMER is recommended and then one coat of TIECOAT is applied. For the initial application, two coats of SILIC ONE are required; afterwards, one maintenance coat per season is sufficient for refreshing, if the hull is kept dry in winter. In the water, however, the coating lasts up to 3 years. No more than 30 days should pass between painting and launching the hull. Application with roller or brush is possible; the surface temperature for processing and curing should be at least 10°C.Technical DataArea of use: Waters with light to medium foulingBoat type: Sailboats and motorboatsSubstrate: HEMPEL SILIC ONE TIECOAT; suitable for GRP, steel, aluminum, and plywoodPrimer: HEMPEL SILIC ONE TIECOAT (Art.

HEMPEL LIGHT PRIMER is a high-quality two-component primer based on epoxy resin for underwater and above-water applications. It serves as a good barrier against penetrating water vapor on rigid substrates, for osmosis prevention and repair on GRP and as corrosion protection on metals. It can also be used on plywood and hardwood. Suitable for interior and exterior use above and below the waterline, as well as for coating keels and rudders.Within the specified recoating intervals, LIGHT PRIMER can also be recoated directly with a subsequent product without intermediate sanding. The surface should be almost dry, but still slightly tacky. For a subsequent coat of antifouling, a coat of HEMPEL UNDERWATER PRIMER (Art. No. 2577-053) is recommended as an adhesion primer.Technical dataSubstrates: GRP, plywood, steel, aluminum, existing coatingsPre-treatment:GRP: sand, clean, remove dustPlywood: seal with a suitable sealerSteel: high-pressure cleaning, sandblasting or mechanical rust removal, dust removalOld coatings: sand, clean, dryPorous surfaces: prime first coat of Light Primer with 20% thinnerSubsequent coat: standard 1K and 2K products (see data sheet)Coverage: 8.2 m²/l at 60 µm dry film thicknessThinner: HEMPEL'S THINNER 845 (Art.
