Kit #2: A Solution for Chrome-Free Surface Treatment
W&F is now launching its chrome-free surface treatment kit! At its foundation are two well established products in modern chrome-free conversion coating chemistry; Ammonium fluorozirconate and Ammonium fluorotitanate. Fluorozirconate is the standard for steel and zinc substrates; fluorotitanate delivers superior performance on aluminium.
Furthermore, with products as Sodium hexafluorosilicate, Phosphoric acid, Disodium phosphate, and Sodium gluconate we complete the bath chemistry — covering surface activation, pH control, and complexation. We can also offer biodegradable chelating agents, such as Tetrasodium glutamate diacetate (GLDA), which provides a sustainable alternative to conventional phosphate-based pre-cleaning chemistry.

Finally, completing the kit are Silane coupling agents — available across coupling, crosslinking, monomer, and polymer grades — deliver the adhesion promotion step that makes the difference between a coating that performs and one that does not.
The result is a full process sequence: clean, convert, and promote adhesion, all from one supplier.
If your operation is under pressure to move away from chromate chemistry, Wintzell & Fried is ready to help!
