®Vinnolit C 65 V is a homopolymer whose small particle size and narrow particlesize distribution have been selected to suit the particular needs of paste making. Due to its extremely low plasticizer absorption at room temperature, the extender resin ®Vinnolit C 65 V lowers the viscosity of plastisols and reduces dilatancy if present.It also increases the shelf life of the pastes. ®Vinnolit C 65 V is used as a blend component together with other emulsion or microsuspension paste grades.

Processing and Application
Plastisols based on ®Vinnolit E 67 ST can be
applied by all commonly used coating
techniques.
®Vinnolit E 67 ST is recommended for the
production of foamed wallcoverings having
smooth or structured surfaces.
®Vinnolit E 67 ST has the following
outstanding properties:
• Medium paste viscosity rates with
slightly pseudoplastic flow behaviour
• Excellent foamability
• Fine cell structure (even with very high
filler loading)
• Very high powder fineness, suitable for
screen printing
• Very good whiteness
