Formulation Support

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
