The effects demonstrated are :

  • For a given shear rate. viscosity is reduced by up to 50% at low shear rates and upto 33% at higher shear rates.
  • When stored for period of up to 21 days, low viscosity is retained
  • Libnol 40 do not have adverse effect on the mechanical properties of cured plastisols and in some circumstances improve them. Since Libnol • 40 is liquid form at formulation temperatures, it's incorporation in plastisol formulations creates no problems.
  • There are additional beneficial effects in using Libnol - 40 viscosity depressants. Libnol - 40 can be used as a post-polymerization additive in E-PVC manufacture, it has also useful antistatic properties.

LIBNOL-40 AS A VISCOSITY DEPRESSANT FOR PVC LEATHER CLOTH

Libnol - 40 is effectively used as viscosity depressant in manufacturing PVC Leather Cloth by spread coating technique.

The major advantages are as follows :

  • Stiffness of Leather Cloth improves as primary Plasticizer is replaced by Libnol 40.
  • Cost gets decreased as Viscosity and thickness is controlled as desired.
  • Finished and feel gets improved.
  • It also helps in dispersion Of pigments and fillers. so this gives better surface and gloss.
  • Dosage recommended is about 5 to 10% of Plasticizers depending upon the viscosity and stiffness desired.
