FINALUX-G 101 acts as a PVC paste thinner although changes in flow behavior of the
plastisol i.e. a slight increase in dilatance is brought about with FINALUX-G 101. In practice as an example, in spread coating, improved leveling behind the coating knife is achieved. The use level in this application is @ 0.5% calculated on PVC + Plasticizer weight.
FINALUX-G 101 is mainly used as pigment dispersing agent in pigment paste for plastisols. A dosage of 10% of FINALUX-G 101 in relation to DOP results in a pigment paste with a much reduced viscosity than in a paste made with DOP alone. The effect may be used to reduce
the portion of the liquid phase in pigment pastes. In Tinting pastes often a separation of the
liquid phase during storage takes place.
FINALUX-G 101 as a part of the liquid phase
will reduce this phenomenon remarkably when
incorporated in pigment pastes.
In PVC plastisols, an improvement in pigment dispersion is achieved and the formation of agglomerates is avoided. This is due to the probable surface active properties of FINALUX-G 101 as it is attracted to the hydrophilic surface of Titanium Dioxide and the remaining alkyl chain of FINALUX-G 101 renders the pigment lipophilic.
The use of FINALUX-G 101 in pigment pastes has resulted in improved colour strength due to its dispersing properties.
