       DC115 Inner-Coated Powder for Industrial Pipe

Properties and Applications  

DC115 is a kind of Epoxy-Phenolic powder coating materials application for chemical pipe especially for the

anticorrosion and wear-resisting oil pipe and drill pipe. Connected with PC8007 resin the DC115 coating layer will

be more useful. It have great anticorrosion character in the high concentration CO2  and H2S medium, Also great

resistance in acid include HCL, H2SO4 HNO3. This coating layer can increase the life of the drill pipe. As the

smooth surface of the pipe can reduce the resistance on freighting the oil, Chemical materials, and other corrosion

liquid. The needed transfer power can be less than normal about 15~30%. As the main component are epoxy and

phenolic the suitable max temperature can reach 120 which main be suitable for most high temperature request field.
