PropGlide® USA Corp, based in Miami, Florida, focuses on non-toxic foul-release coatings for marine propellers and running gear. After developing the technology in 2006 and introducing it to the market in 2016, they provide an alternative to conventional biocidal antifouling paints. Their system relies on a silicone polymer surface that makes it difficult for barnacles and slime to bond, ensuring the hardware stays clean through seasonal use. The product range, often represented in Italy by Osculati, is designed for both DIY enthusiasts and shipyard technicians. It is not an antifouling paint in the traditional chemical sense, but rather a functional coating that requires proper surface preparation to perform. The system consists of a primer to ensure adhesion to the metal substrate and a clear silicone topcoat that provides the low-friction finish required for effective foul-release. When you choose this brand, you are opting for a maintenance approach that favors surface properties over chemical toxicity. It is a suitable choice if your boat spends significant time in the water and you want to maintain propeller efficiency without the environmental footprint of traditional copper-based bottom paints. Proper application is essential, as the effectiveness of the silicone layer depends on the bond established with the primer during the initial treatment.
Silicone technology for running gear maintenance
The PropGlide system is engineered to handle the high shear forces present on spinning propellers and shafts. By replacing traditional biocides with a smooth, inert polymer, the coating allows for easy cleaning throughout the season. These are the core components of the system: Primer Base and Hardener, a two-part epoxy system that creates the chemical bridge between the bare metal and the silicone finish. Clear Topcoat, the proprietary silicone polymer that creates the slick, low-surface-energy barrier against marine life. Complete Kits, available in sizes ranging from Sailboat to Extra Large, covering different propeller surface areas.
