TCI products were especially formulated for chemical protection and repair of infrastructures, including water and wastewater facilities to protect concrete, brick, masonry, and steel surfaces against sulfuric acid, gases, and other chemicals usually found in the wastewater headspace.
In-house testing of bare coating specimens has shown that the coating system, when exposed to sulfuric acids with different solution concentrations, tends to gain weight and thickness rather than being corroded.
Severe Wastewater Analysis Test (SWAT), carried out by a third-party, has proved that ProTecStrong 855-SPL has a good resistance to the accelerated severe exposure as per ASTM G210.
Adhesion of TCI 855- SPL to steel and concrete substrates was tested as per ASTM D4541 and ASTM D6677. The coating was found to have very good adhesion to substrates after SWAT exposure, which meets or exceeds the related ASTM requirements.
