ROWAFLEX® TH 3

Highly efficient synthetic Thickener for aqueous pastes and polymerdispersions

Type Thickener
Chemical Basis Polyacrylic acid derivative
Appearance yellowish, low-viscous liquid dispersion
pH-Value 8 - 9
Ionogenity anionic

Properties

ROWAFLEX® TH 3 is a thickener for polymer dispersions. The excellent efficiency of
ROWAFLEX® TH 3 makes it possible to significantly reduce the amount of use
compared to conventional thickeners. To achieve the high efficiency of the product
is in the neutral and in the alkaline range.


ROWAFLEX® TH 3 gives the polymer dispersion following properties:

  • reaches the final viscosity after short mixing time in high field intensity
  • improves the dispersing ability of thermoplastic powders
  • gives stability to the paste
  • has a positive influence on the rheological behavior of the paste
  • extends the storage times of the finished paste
  • high viscosities can be reduced with water
  • is self thickening , no adding of ammonia necessary

Application

ROWAFLEX® TH 3 is a special thickener for thermoplastic powder/aqueous dispersions that are applied on rotary printing equipment.

The required quantity of the finished product varies depending on the print template (mesh
number/CP) and is between 0.2 and 0.5% in relation to the total paste quantity (evaluate a
final viscosity of approx. 2.500-4.500 mPas).
