Chemola™ Desco Polymel 422
Enhanced Hydrocarbon Service
Chemola™ Desco Polymel 422 now has enhanced hydrocarbon resistance with a specially formulated polymeric lubricant base and unique combination of solid additives. Polymel 422 offers superior metal adhesion under the most demanding conditions, temperatures and pressures. This new formulation has advanced corrosion inhibitors for increased resistance to oxidation. Because it is resistant to acids and alkalis it will not wash out during pipeline maintenance. Polymel 422 can be used as a coating on metal surfaces to protect from acidic environments.
Chemola™ Desco Polymel 422, with its wide temperature range, superior adhesion and chemical resistance covers the widest range of applications. It performs excellently with gate, plug and ball valves throughout oil and gas production operations, pipelines and petrochemical plants.
Recommended Uses
Chemola™ Desco Polymel 422 can be used with acids, sour crude and gas, alkalis, aliphatic hydrocarbons, butane, gasoline, hydrofluoric acid, jet fuel, kerosene, natural gas, diesel, salt water, sand slurries, condensates and propane.
