Properties and application

TRUPON MY reduces the fixation rate of anionic dyestuffs on leathers and provides good through penetration properties. Its amphoteric properties allow an excellent exhaustion on retanned and chrome tanned leather.

TRUPON MY dispersing properties on anionic dyestuffs improves the dyes stability and solubility. It thereby produces increased bright<ness and dye intensity, even under unfavourable conditions (short baths, dissolution in cold water, dyestuff not fully soluble in water, etc.).

TRUPON MY produces good levelling on wool sheepskin leathers.

Some incompatibilities may arise if used together with vegetable extracts and some acrylic-retanning agents in the same bath.

Required quantities:

- through-dyeing of leather:      0.5% - 1.0% on shaved weight.
- wool dyeing:                           1.0 - 2.0 g/l.

Storage Stability: TRUPON MY can be stored for up to one year, if temperatures below 5ºC and above 40ºC can be avoided. On prolonged storage or extremes of temperature TRUPON MY may exhibit some settlement which can be rectified by stirring the product thoroughly before use.
