Application
Printex BS screen printing ink was developed for printing especially on synthetic fabrics, viscose, artificial silks, swimming costumes. With the help of Printex BS printing paste you can produce elastic, bright coloured prints with soft touch on white or light coloured textiles.
- 80 - 100 % Printex BS
- 0 - 5 % pigment or
- 0 - 15 % fluo-pigment
The colouring pigment has significant influence on fastness (wash-, rub-, light).The ink can be thinned with water and can be thickened with Printex V or Printex VA afterthickener additives. For lowering viscosity of the inks, we recommend adding Catalyzer D instead of water.
Very small amount can lower the viscosity significantly, and improves the fixing of the ink, catalyses the cross-linking at thermosetting.
- Adding 1-8 % Fixirer-2 reactive synthetic resin improves rub- and wash fastness, but can ruin the soft handle, the fabric become stiff.
- Adding 0.5 - 1% Catalyzer SV, makes printing possible on synthetic fabrics, which are not suitable for thermosetting.
- The ink can be mixed with Fixirer-2 and Catalyzer SV in the same time.
Thermosetting of the print
Always use thermosetting for textiles made of synthetic fibres predominantly.
- in heated chamber 130 - 150°C 3 - 5 min
- with contact heat 160 - 180°C 15 - 20 sec
- adding Catalyzer SV 130°C 15 -20 sec
Recommended mesh
PE monofilament 34 - 68
Recommended emulsion
Fotecoat 1010
Fotecoat 1915
Storage
In closed container, protect from freezing. Shelf life: 6 months. After long storage, thorough stirring is recommended.
Note
Please, always make a test print before starting production runs. Make sure that expected fastness properties can be achieved with the actual base materials within your technological conditions!
