Acidic (Low pH) product (pH<4)


These specially selected dyes are intended for use in dyeing industrial products where color stability in acidic environments (pH<7) is critical.

Acid stable dyes exhibit improved stability in acidic solutions compared to most dyes. However, the stability of these dyes cannot be guaranteed in all solutions. It is essential that thorough testing be completed on a sample basis BEFORE proceeding to use these dyes on a production level.
