WS Retarder PPA 80/20

WS Retarder PPA 80/20 is a professional-grade solvent blend developed for use as a retarder in compatible solvent-based flexographic printing inks.  It is especially designed to help control solvent evaporation and maintain suitable ink working characteristics during flexographic printing.

For best results, add gradually while monitoring ink viscosity, drying behaviour and print quality. The appropriate addition level will depend on the ink formulation, press speed, substrate, ambient conditions and manufacturer's recommendations.

Key Features

• Composition: 80% Propanol & 20% Propyl Acetate

• Designed specifically for flexographic printing applications

• Helps slow solvent evaporation in compatible solvent-based inks

• Helps reduce premature drying of ink on the plate and anilox

• Supports consistent ink flow and transfer during printing

• Useful for managing ink drying behaviour under challenging press conditions

• Suitable for press-side adjustment when recommended by the ink manufacturer

• Ideal for professional and industrial flexographic printing operations
