Specifications

Pigment Printing Thickener (EM-618A)

1) General Description
 EM-618A Thickener for pigment printing is an anionic acrylic polymer, serving as printing carrier in coating printing on textiles. EM-618A can be equal with PTF thickener in performance, but its price is more competitive than that of PTF.

2) Technique Data 

Appearance                      Solid content            Viscosity                                    PH value

yellowish viscous emulsion  36±2%     65.000~80.000mpas        6~7 (Acceptable PH 4~12)

Thickening capability:

Mix with water  2.3% dosage of EM-618A,rotary viscosity can be higher than 25pa.s.

3)Property and features  

1. Good fluidness, easy to mix with other water-based materials.
2. Strong water cohesive and thickening capability under high-speed stirring.
3. High consistency with printing binder, pigment pastes and other textile printing auxiliaries.
4. If pigment doesn’t reach enough consistency, then thickener can be added, which won’t have ill impact on printing result.
5. High thickening capability. 2.3% in flat screen printing and less than 2.0% in rotary screen printing.
6. High quality stabilization. Free from dilution or bad smell.
7. Good color yield, sharp definition and soft hand feeling.
8. Bring thickening effect to printing paste, and the prepared paste can mix with all kinds of oil-covering water-based paste.
9. Applicable also in bringing better thickening effect to rubber paste, transparent paste, color-printing paste, if consistency is not high enough.

4) Usage

1. On preparing printing paste, add appropriate dosage of EM618 to measured water and stir at high speed until reaching required consistency.

2. In case printing paste is not viscous enough, then add some EM618 when stirring.

5)Safety Notes 

1. Thickening ability in soft water is better than that in hard water.

2. Don’t mix with cationic auxiliaries.

3. One year of guarantee under storage temperature 0-40°C.

4. Please use cloth or soft paper to clean when getting blotched by thickener, and wash with salt electrolyte and water.

Notes: Above usages have been proved through practice. But considering practical printing techniques, please choose the right manufacturing process after experiment.
