Cortec M-138 Cortec Corrosion Inhibitors Rubber - Elastomer (Chloroprene, Butyl …) ADHESIVE >> Hot-melt SEALANT >> Pre-formed tape / Gasket Powder form additive for synthetic elastomers and natural rubber. High heat tolerance. Also good in hot melt adhesives. Cortec® M-138 and M-138 C are Volatile Corrosion Inhibitor (VCI) powder masterbatches for use in the Rubber and Sealant Compounding Industry. Corrosion protection for multimetal parts, either in contact or in close proximity to rubber rollers, gaskets or manufactured parts is a major problem that is often solved only by use of environmentally unfriendly coatings or expensive alloys. Cortec® M-138 and M-138 C are powdered compounds that can be added in low concentrations to rubber formulations to solve these basic problems. M-138 C is designed for applications involving aluminum and cast iron. It should not be used when copper is present. A finished rubber part can contain both a contact corrosion inhibitor and an emitting source for VCI chemistry. These products open up new design and cost saving solutions to industry and manufacturing process, and to anyone that has had problems with metallic components in contact with elastomers. FEATURES • Provides multimetal corrosion protection to finished products • Allows addition of VCI compounds at the compounding stage • Provides true VCI emitter properties to finished rubber products • Gives greater design freedom in choice of materials • Reduces the cost of corrosion protection for metal components • Non-toxic and non-flammable additive • Simplifies mix design for compounding of elastomers APPLICATIONS • Rubberized coatings • Elastomeric gaskets and sealants • Steel belted radial tires • Reinforced rubber hoses and belts • Elastomeric parts and components • Elastomeric membranes for auto roofs Volatile corrosion inhibitor. Possesses non-toxic and non-flammable properties. Provides multimetal corrosion protection, freedom in choice of materials, true VCI emitter properties and high heat tolerance. Used in hot melt adhesives, gaskets, rubber and sealant compounding industry.
