What is PropOne Underwater Light Coating ULC and why choose it
PropOne Underwater Light Coating ULC by Prop-One is a two-coat foul release system designed to protect submerged marine components. It combines an anti-corrosive Primer Coat with a Clear Coat foul release layer. The Clear Coat is a non-biocidal, low surface energy coating that reduces the strong adhesion of fouling organisms on surfaces permanently immersed in water. Once the vessel is underway, attached organisms are easily dislodged by mechanical action.
The system does not control fouling by poisoning the environment. Instead, it creates a smooth, low-adhesion surface that facilitates the physical removal of marine growth when the boat is in drive.
Main features
- Two-coat protection system: anti-corrosive Primer Coat plus Clear Coat foul release layer.
- Non-biocidal Clear Coat: low surface energy technology that does not rely on biocides to prevent fouling.
- Mechanical fouling release: marine organisms are weakly attached and are removed when the vessel is operated.
- Coverage efficiency: a 1 litre kit covers approximately 3.8 m² of surface area.
- Suitable for multiple marine alloys: can be used on all ferrous and non-ferrous marine alloys, including aluminium.
- Controlled application process: clear instructions for mixing, surface preparation and application for optimal performance.
- Not suitable for aquaculture: the product is not designed for aquaculture applications and must not be applied to anodes.

Applications and use cases
PropOne Underwater Light Coating ULC is intended for use on fast-moving components and running gear permanently immersed in water. It is suitable for:
- Propellers of various diameters and blade counts.
- Rudders, propeller shaft struts and trim tabs when included in the kit sizing table.
- Marine alloys where corrosion resistance and foul release performance are required.
The product is applied after thorough surface preparation, cleaning and inspection, followed by two coats of Primer and a single Clear Coat layer. Fouling organisms that build up while the vessel is stationary are intended to be released mechanically once the vessel is operated.
FAQ
1. Is PropOne Underwater Light Coating ULC biocidal?
No. The Clear Coat is a non-biocidal, low surface energy coating. It does not prevent marine growth by chemically poisoning the environment.
2. How are fouling organisms removed from the coated surface?
When the vessel is not in use, the surface can be colonised by organisms. These are removed mechanically when the boat is placed in drive and water flow acts over the coated surface.
3. On which materials can this coating be used?
The system is suitable for use on all ferrous and non-ferrous marine alloys, including aluminium. It must not be applied to anodes.
4. Is the product suitable for aquaculture installations?
No. The coating is not suitable for use in aquaculture applications.
5. What are the minimum conditions for application and curing?
The minimum application temperature is 5 °C, with recommended minimum application conditions of 10 °C and 55 % relative humidity. At 20 °C and 55 % RH, time to immersion is approximately 12 hours.
6. How long can I use the mixed primer?
The pot life of the mixed primer is approximately 4 hours at 25 °C.
7. How should tools be cleaned after application?
Clean tools and equipment used with the Primer using acetone immediately after use. Clean tools and equipment used with the Clear Coat using xylene.
8. What safety information should I review before using the product?
You should review the product label and Safety Data Sheet (SDS) for safety and caution information before use and follow the manufacturer’s safety recommendations when using any solvent.
