Consider adding the surface cleaning and organic deposit penetration and dispersion power of DTEA II® to your one-drum corrosion and scale inhibition water treatment chemicals program.
Please Note: The key to successful formulation of DTEA II with typical scale and corrosion inhibitors is low pH (less than 2).
- XRF 4025 and 4026 – Examples of stable formulations containing typical scale and corrosion inhibitors with DTEA II
- XRF 4015 and 4017 – Examples of Azole-free formulations with the added copper corrosion inhibition of DTEA II
- XRF 4121, 4122, 4131, 4132 – Examples of formulas designed for treatment of waters of two different scaling index
