From the ecological aspect conventional chrome tannage has got a major problem: only 70 - 80% of the chrome offered is fixed in the hide 20 - 30% of the chrome is discharged with the waste water Requirements: For both ecological and economical reasons a tanning method is required: - with a higher chrome exhaustion - reduced use of chrome tanning agents - reduced environmental costs The properties of the leather White appearance clear even pastel shades Very good light fastness Very good heat resistance High shrinkage temperature up to 80C Excellent physical strength characteristics Excellent hydrothermal stability Low dry shrinkage Excellent water vapour permeability Inherent flame retardancy Saving on Dyestuff cost Your pole position: Sandoderm Dyes homogeneous dyes and mixtures metal complex dyes with excellent fastness properties (light-, migration to PVC, wet fastnesses etc.) excelle
