CORIPOL® ALF – lecithin-based fatliquor for all soft articles
Features
®
CORIPOL ALF is a turbid, brown liquid based on natural phospholipids.
Charge: Anionic.
Handling & storage:
Wear goggles and gloves during handling. ALWAYS STIR BEFORE USE
and close containers tightly afterwards.
Can be stored for about 1 year (from date of production) if kept between
10°C and 35°C. In any case protect from frost and heat above 40°C.
If product becomes frozen, warm to approx. 20°C and stir before use.
Method of emulsifying:
®
CORIPOL ALF should be thoroughly mixed with the other fatliquoring
agents being used. A homogenous emulsion can then be prepared with
warm water in a ratio of 1:4.
Benefits
®
CORIPOL ALF is pumpable and easy to emulsify. It is a highly
concentrated fatliquoring agent which allows the maximum softness to be
achieved with a minimum offer.
Leathers obtained by its use are characterised by: -
Application:

a particularly good, inner softness

a smooth and silky surface handle

improved tensile, tear and stitch-tear resistance

good gravimetric fogging behaviour

good heat & light fastness properties
®
CORIPOL ALF can be used as a single fatliquor for soft, light-weight
articles or more often, as a companion fatliquor in combination with other
®
CORIPOL brands to achieve the desired leather properties.
®
CORIPOL ALF provides at a rather low offer, equivalent softness
compared to higher additions of conventional fatliquors. The gravimetric
®
fogging values and physical properties imparted by CORIPOL ALF
comply with the latest specifications of the automotive industry.
