TCI products have passed extensive testing programs which demonstrate the superior quality of our products in terms of their mechanical, physical, and chemical protective properties.

The testing program of TCI products included the following:

1 - ANSI NSF 61 and ANSI NSF 372 testing for potable water applications.

TCI Products have passed the rigorous testing program of NSF 61 and SNF 372 for potable water applications.

TCI cares about the safety of the Public by providing safe repair and coating materials for the needs of any project.

Continuous maintenance testing of our products is carried out periodically by NSF professionals to ensure that our products meet the NSF standard at all times.

2 - Bond strength to various substrates:

One of the major factors affecting the integrity and performance of coating systems is the bond strength between the coating system and the substrate. Failure of bond between the coating system and the substrate leads to progressive debonding of the coating system and loss of the required protection against chemical attacks.

Exclusive bond strength to concrete, masonry, brick, wood, and metal substrates has been achieved by third-party on-site and laboratory testing. 

Concrete surface saturation by TCI primer resulted in an increase/enhancement of the concrete bond strength by 6% to 7.5% depending on the type of primer being used.

TCI products bond strength to new concrete sewer pipes was found to be in the range of 4 to 5 MPa [600 to 700 Psi] depending on the moisture/dampness of the substrate surface.

3- Hydrostatic Pressure Testing:

Wastewater pipes are installed at relatively deep depths underground to allow for gravity flow. The depth of some sewer pipes can be as low as 50m below ground. Hence, the sewer pipes are exposed to high hydrostatic pressure from the underground water table. Therefore, municipalities usually require coating systems to withstand at least a hydrostatic pressure of 6 bars.

With a safety factor of 2, TCI products can withstand a hydrostatic pressure of at least 14 bars for wet primer TCI 800-W and at least 18 bars for the dry primer TCI 800-D.   

4 - Chemical Resistance Testing:

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.

Hydraulic Analysis by the Utah Water Research Laboratory

After my inspection and analysis, it is my expectation that the ProTecStrong 855-SPL product, when properly applied to the interior of a conveyance channel, will produce Manning’s n values that are equal to that of PVC pipe. Based on the calculations that I have completed, the expected Manning’s n value for the surface resulting from product application will be in the 0.009 range and perhaps even slightly lower.
