Polyscreen PS is a two-pack screen ink combining outstanding resistance to many chemicals and solvents with excellent adhesion to an extensive range of ‘difficult’ surfaces.


Polyscreen PS inks are supplied in two parts (ink and catalyst). The tin containing the ink has sufficient space to take the catalyst which must be added to cure the system. Before printing, estimate the amount of ink required for a day’s work and thoroughly mix the ink and catalyst together in the following ratios: Polyscreen Inks: 5 parts by weight Polyscreen Catalyst: 1 part by weight Polyscreen Varnish: 3 parts by weight Polyscreen Catalyst: 1 part by weight Polyscreen Matt Catalyst is available to obtain finishes ranging from satin to matt by varying the mixing ratio from 5:1 for a satin finish to 1:1 for a matt finish.


Polyscreen PS dries by a combination of solvent evaporation and a chemical reaction between the base and catalyst. Air drying times can be as fast as half an hour using ZV551 Thinner and Cleaner or as slow as 5 hours when using ZV574 Retarder. At room temperature, full chemical resistance and adhesion are not developed until about 4 days after printing.

Adhesion and outdoor weather resistance are enhanced and drying times considerably reduced if Polyscreen is dried at elevated temperatures, however, Polyscreen inks are not recommended for use in applications where prolonged outdoor exposure is a possibility
