Shenesin JPL
【Chemical Nature】
Compound of modified aliphatic aldehydes
【Properties】
Shenesin JPL has tanning effect in a wide pH range ( pH2 ~ pH8 ). When used as pretanning agent before chrome tanning, it will help the penetration, distribution and absorption of chrome, resulting in a fuller and tighter wetblue with finer grain and less chrome content in the residue float.
Shenesin JPL has dispersing effect on fats. When used in fatliquoring, it will enhance the the fatliquoring effect and reduce the risk of loose grain.
Shenesin JPL is suitable for nappa, upholstery and garment leathers where the softness and fullness are important.
【Characteristic features】
Physical form: Light yellowish liquid
Effective Substance (%)：≥20
PH Value ( 1:10 )：5.0~6.0
【Application】
Shenesin JPL can be used before chrome tanning and retanning, before neutralization, in retanning and in fatliquoring.
The dosage is normally 1% ~ 4% based on shaved weight.
【Transportation and Storage】
Shenesin JPL is categorized as non-DG cargo, can be transported and stored normally. The powder and liquid products have a shelf life of at least one year if they are stored in their tightly sealed original packaging at temperatures between 8℃ and 40℃. Drums should be tightly resealed each time material is taken from them, and their contents should be used up as soon as possible after they are opened.
