A: PROTEGOL® is normally used on buried or submerged pipes for oil, gas, water and slurry, tanks, valves and fittings, both on the external and internal face of the structure. It is used in new construction and rehabilitation projects alike, both applied in factory and field.
A: The coating thickness varies depending on the project specification, the specified and selected product, norms and standards and specific requirements. It may start as low as with 100 µm (4 mils) for PROTEGOL® Flowcoats. There is virtually no upper limit, for example if the project asks for anti-abrasive features. For 100 % solids PROTEGOL® the wet film thickness equals the final dry film thickness.
A: There is really no upper limit. PROTEGOL® has already been applied to 126’’ OD pipe. Our systems guarantee tailored solutions across a variety of applications, from small, simple components to large and complex geometries.
A: PROTEGOL® Coatings are either spray applied by specialized airless hot spray equipment with the proper mixing proportion or air-assisted pneumatic manual dischargers. Diverse formulations are processed manually by brush, spatula or roller.
A: The first PROTEGOL®-coated specimen was put into service in the 1960’s. The first major pipe rehabilitation project was undertaken in Texas/US in 1989. In this occasion, TIB Chemicals was one of the key players in developing the first spray ring for line coating, enabling rehabilitative coating of the line without prior dismantling.
A: Most of our PROTEGOL® Coatings are based on aromatic polyurethanes, some are based on epoxy resins and some more recent developments include polyurea and polyurea hybrids.
A: PROTEGOL® is manufactured in TIB Chemicals’ headquarters in Mannheim, Southern Germany. PROTEGOL® is a TIB Chemicals trademark.
A: Good surface preparation is essential as it profoundly affects the performance of a coating. Poor surface preparation invariably develops a poor adhesive bond between coating and substrate and causes pre-mature coating failure. The surface preparation through abrasive blasting performed by high-pressure special machines allows cleaning the surface thoroughly from deposits and residues to ensure an optimal coating adhesion. The result must be a near white Sa 2 ½, an angular anchor pattern and a profile according to DIN EN 10290, 6.1.2. The constructional shaping has to conform to DIN EN 14879, part 1. Adjacent or underlying coatings as well as small touch up areas may be prepared divergently.
A: There have been PROTEGOL®-coated structures in service for more than 40 years, and thousands of valves have been in use that long.
A: Touch up is easily done with the same spray or manual product thus obtaining a final homogeneous coat.
