DTK-70 Inner-Coated Powder for Transmission Pipe
¡¡
DTK-70 is a thermosetting epoxy powder coating for inner coater of pipeline. It meets with PC8007 red primer
to make high-quality coating. Which has the tough, excellent flexible, high impact resistance, high gloss, thick-
film coating for secondary and recovery system, particularly CO2.
The coating surface is very smooth, which greatly improves the hydraulic efficiency of the pipeline system. It is
very suitable for CO2, injection, oil and gas, sewage and other working conditions that need to improve corrosion
resistance. Her film thickness is generally more than 250 microns, and it is applicable to all kinds of transmission
pipes, sliding sleeves, fittings, etc. below 105 ¡æ (221F).
