SYNTEX DIBS
1. COMPOSITION
Organic product in aqueous solution free of any compounds based on aldehydes.
2. PHYSICAL & CHEMICAL PROPERTIES
Aspect : liquid
Colour : brown
pH (10 % solution) : 3.5 +- 1.0
Density : 1.2
3. CHARACTERISTICS
SYNTEX DIBS is used on pickled skins or hides for pretanning and is an interesting substitute to products based on aldehyde.
SYNTEX DIBS gives a white leather with very good light fastness. SYNTEX DIBS has the advantage of containing neither aldehyde nor formaldehyde. With vegetable and synthetic tannins, tanners obtain leather with very low free-formaldehyde content.
Hides and skins pretanned with SYNTEX DIBS can be shaved without any difficulty with a better value for the shavings.
SYNTEX DIBS allows a very quick chrome tanning.
Fatty skins pretanned with SYNTEX DIBS can be degreased at a temperature of 50°C without any risk. This is a very important advantage for tanners for a complete degreasing in hot water which can be made with our Degreaser, Synerpal UC 100.
4. APPLICATIONS
- SYNTEX DIBS should be added without dilution in the drum as some precipitation could occur with water at pH>4,0.
- Pretanning of hides (upholstery, automotive leather) : 2-3 % on pelt weight. Used at pH < 3.5 it needs to be neutralised at pH 4.5/4.8 before samming and shaving.
- Pretanning before degreasing : 2-3 % on pelt weight. pH should be raised to 4.6 before degreasing.
Afterwards, skins are put in bath with SYNTEX PRA (2 %) during 1 hour before chrome tanning.
