Naval Jelly Rust Dissolver
Description
[Loctite] A registered trademark for a commercial rust remover. Naval Jelly contains Water (65-70%), Phosphoric acid (25-30%) and Sulfuric acid (1-3%) in a gel matrix composed of a thixotropic polysaccharide (1-3%), isopropanol (1-3%), Surfactant (1-3%) and Silica (0.1-1%). The phosphoric acid dissolves the Rust (iron oxide) and then reacts to form iron phosphate. The iron phosphate provides a thin protective coating to minimize further oxidation. For treatment with Naval Jelly , the pink gel is brushed on the metal surface, allowed to stay for 5-20 minutes, then rinsed off. The acids are then neutralized with a bicarbonate|baking soda paste. In addition to removing rust, Naval Jelly is used to prepare Iron and Steel surfaces for painting.
