Properties

TRUPONOL OST is a highly sulphited fatliquor based on high-quality fish oil. Due to its outstanding stability to electrolytes TRUPONOL OST can be used in both chrome tannage and retannage where it will help promote smooth flat grain characteristics along with excellent softness.

TRUPONOL OST will exhaust readily from the fatliquor bath and possesses excellent fibre substantivity, thus making it ideally suited to high speed drying techniques such as toggling or vacuum.

Application

TRUPONOL OST shows excellent emulsification properties and can be used to advantage together with raw oils from both natural or synthetic sources.

TRUPONOL OST can be used to good effect at levels of 1 - 3 % together with other anionic fatliquors such as TRUPON® DXV in the production of shoe upper leather.

TRUPONOL OST can be stored for up to one year, if temperatures below 5 °C and above   40 °C can be avoided. On prolonged storage or extremes of temperature TRUPONOL OST may exhibit some settlement which can be rectified by either warming and/or stirring the product thoroughly before use.
