Sanodure® Black CRO
Aluminum Dye
Sanodure® Black CRO is a homogeneous water soluble black dye with rapid adsorption dyeing of anodized aluminum.
Sanodure® Black CRO is of primary interest for finishing processes in which rapid dye absorption is desired and the fastness properties are of secondary importance.
Only recommended for interior use.
