CHELFAC HW-1 is a blended sequestrant, which is effective over a wide pH range.

Metallic ion contamination can adversely affect the color, stability and efficiency of textile processes. Incorporation of CHELFAC HW-1 into these processes can eliminate the adverse effects.

CHELFAC HW-1 is effective at sequestering copper, iron, calcium and magnesium in water supplies, acidic solutions and up to pH 10 - 11 in alkaline solutions.

The required concentration of CHELFAC HW-1 will vary depending on the application but recommended concentrations for initial trials can be obtained from your DYETECH, INC. sales representative.
