IMS Company (Chagrin Falls, OH) offers the Night Coat Rust Preventive and Acid Neutralizer, which is a dual-purpose rust preventive and acid neutralizer. It can be used alone to prevent rust overnight and in the short term, or it can be used as an acid-neutralizing surface-preparation for IMS Step Two or other longer term rust preventive. A neutralizer such as Night Coat is a must when molding PVC or CPVC—where out-gassed hydrochloric gas combines with any moisture to create corrosive hydrochloric acid. The metal must be neutralized to prevent the long-term rust preventive from sealing in the acid and its resultant corrosion. Night Coat penetrates and runs—quickly wets out across the mold and displaces moisture, neutralizes acid and protects finely polished metal surfaces. It is easily removed with startup shots in injection molding or with standard solvents.
