Potenza Open Gear 99 BIO is an excellent adhesive, high-tech lubricant, which is based on the newest technology combined with biodegradability. Open Gear 99 BIO contains a synergistic combination of white and black solid lubricants for extreme application, e.g. boundary lubrication. The product also contains chemical EP (extreme pressure) additives which in combination with the solid lubricants give you a hydro elastic lubricating film which anchors itself to the metal surface thus eliminating wear, tear and pitting. It has very good water resistance behaviour even in seawater and at higher temperatures.
