Chain Lubricant - NSF H1 OVEN CHAIN LUBRICANT is the answer to oven chain lubrication. It can also be utilized effectively in gear lubrication applications. It's derived from a carefully evolved blend of high viscosity, non-smoking [550°F (288°C)], low odor synthetic fluids and surface tension modifiers. These lower the surface tension of the high viscosity fluids allowing them to move effectively to penetrate into the links and pins of the chain and lubricate the chain roller. Benefits of using Oven Chain Lubricant™ Contains PTFE Low odor Reduced smoke Non-corrosive Specifications: Base Materials: Inorganic / Synthetic Certifications: NSF H1 Registered #113601 Service Rating: -25°F to 752°F, -32°C to 400°C TDS SDS
