3LPE coating. After the application, the test items were moved outside and left in a storage area for over 100 hours. The next step in the testing process was to remove the HinderRust with high-pressure hot water (60°C at 110 bars) and to verify the complete removal. After washing, all the pup test pieces were transported to a dark room for a UV lamp check on the cleaned surface. The UV lamp test results showed no residual HinderRust on the washed areas. The third stage was to apply a field joint coating to the prepared areas on the slotted pipe. Extensive tests were conducted after the field joint coating was applied to ensure that no anomalies were found that could be traced back to the application of HinderRust. The pre-welding testing and processes included peel tests, bevelling the pup pipes, checking lamination and welding.

Conclusion HinderRust R2.0 proved to be an excellent rust-stopping product for the TAP project. Not only did it provide needed corrosion protection, but the welding, non-destructive and field joint coatings testing showed no anomalies linked to HinderRust. About HinderRust HinderRust is a solvent-free rust stopper and lubricant. It is engineered with Tufoil Technology, a proprietary PTFE chemistry that is non-flammable and will not evaporate. The Tufoil in HinderRust acts as a lubricant and wetting agent that spreads HinderRust across the treated surface, displacing water and enabling HinderRust to bond to the surface and protect it from corrosion.

About Fluoramics Fluoramics, Inc is a manufacturer of sealants, greases, lubricants and rust inhibitors, all of which are engineered PTFE solutions. Founded in 1967, the company is based in Winona, Minnesota, and manufactures all of its products in the USA.

HinderRust R2.0 provides temporary surface protection for metal parts that need protection after fabrication, or during storage and transportation. It is removable by washing to allow for final finishing. HinderRust R2.0 is suitable to use for storage, temporary surface protection, metal fabrication, transportation, machined parts, castings and stampings. It is a penetrating lubricant and rust stopper/breaker.
