40-1DR Dacroment Connector Link Precision ANSI Roller Chain - 1/2" Pitch - Dacromet coating is a special combination of liquid zinc and aluminum. The chains are coated in multiple layers of Dacromet to provide excellent corrosion resistance in extreme moisture conditions, chemical wash down and other harsh environments. Dacromet coated chains provide the working strength of a carbon steel chain and the corrosion protection of a stainless steel chain. Dacromet coated chains will not flake or chip like a nickel plated chain. Dacromet Chains can be used around food conveyors but can not be in direct contact with food. Dacromet Chains offer considerable cost savings when compared to Stainless Steel Chains.
