Project Description
Client was seeking a gas pipeline coating system spanning 11 states from Texas up to Minnesota which can be applied in various types of climates ranging from hot and humid to cold and wet. Additional infrastructure included bullet tanks, vessels, supports and bollards. Some gas pipelines could not be shut down and would have to be applied while online and sweating.
Coating Solution
Dry Surface Spec :
2 coats Rust Armour® each @ 4 mils DFT;
1 coat PanegrafTM Polyurethane Anti-Graffiti Topcoat@ 4 mils DFT.
Wet Surface Spec :
2 coats of EpoprimoTM Moisture-Resistant Solvent-Free Epoxy Primer each @ 4 mils DFT;
1 coat of PanegrafTM Polyurethane Anti-Graffiti Topcoat@ 4 mils DFT.
Results
A flexible coating system was specified for applicators which could be used interchangeably as the climate and weather conditions changed. When the surface was dry enough Rust Armour® was used, but when the surface was wet or sweating then EpoprimoTM Moisture-Resistant Solvent-Free Epoxy Primer was used. The topcoat was always PanegrafTM Polyurethane Anti-Graffiti Topcoat unless the surface was so wet that a polyurethane could not be used and a third coat of EpoprimoTM Moisture-Resistant Solvent-Free Epoxy Primer was used in the desired tint. Surface prep range from NACE 3 Commercial Blast to 4,000 psi power wash depending on the severity of corrosion. Application times were significantly improved due to the moisture cure (humidity accelerates curing) properties of RUST GRIP and the wet surface cure characteristics of PanegrafTM Polyurethane Anti-Graffiti Topcoat.
