Let AMSA help you bring 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.
AMSA, Inc. formulation support includes:
- Advice on conditions under which DTEA II-containing formulations are stable
- Testing of chemical component interaction
- Testing of overall formulation stability
Sample Formulation Recipes
The following examples illustrate the ability to formulate DTEA II™ (BCP™ 1100) with traditional scale and corrosion inhibitors.
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 – Azole-free formulations which utilize the copper corrosion inhibiting ability of DTEA II
- XRF 4121, 4122, 4131, 4132 – Formulas designed for treatment of waters of two different scaling index
