Toynol^® DS-197 dispersant for subimation dyes, disperse dyes in digital inks 



Characteristics Chemical Components

Mixture of Amine alkyl hydroxy affixture of HMW styrene acrylic copolymers and surfactant

Recommended Applications

Phthalocyanine organic pigment(blue/green)
Azo organic pigment(red/yellow)

Physical properties
Grinding operation

Dispersing sand mill, Glass bead(0.8-1.2mm), Filling rate 70%
3000rmp/min  60min

Performance evaluation

• Centrifugal stability: take 20ml millbase into centrifuge tube, centrifuge 10 min under condition of 3000r/min, then take out to observe the layering of millbase. Pour out liquid and calculate amount and percentage of precipitate.
• Viscosity evaluation:Use Brookfield rotational viscometer.
• Fineness measure:Scraper fineness meter
• iscosity stability:Store millbase in 100ml wild-mouth bottle at 40ºC for 24 hours, measure viscosity change,  ±50% change is regarded qualified.

Example1(★:Excellent  ☆:Good )

Experimental pigment: phthalocyanine green G, powder content 30%
Pigment content:                  30
Dispersant dosage(as supplied):    20
Defoamer(Toynol^®):               0.1-0.3
Wetting agent(Toynol^®):           0-0.3(as appropriate)
Water:                          add to 100%
Example2(★:Excellent  ☆:Good )

Experimental pigment: permanent yellow P.Y.12, powder content 35%
Organic pigment content:          35
Dispersant dosage(as supplied):    20.4
Defoamer(Toynol^®):               0.1-0.3
Wetting agent(Toynol^®):            0-0.3(as appropriate)
Water:                           add to 100%
 

(When actual operation:First add dispersant into water, then add powder, 4000rmp/min 10min. After powder completely wetting, put into grinding glass beads to start timing grind.)

Recommended Applications

• Water-based inks
• Architectural coating
• Wood and furniture coatings
• Automotive coatings
• Can coatings
• Anticorrosive paint
• Leather coatings

Operation proposal

1. Suggested dosage of organic pigment(Based on pigment, Toynol^® dispersants calculate solid content SOP):10-50%;
2. Do not add wetting agents separately;
3. Toynol^® wetting agents can accelerate original powder wetting;
4. Adding Toynol^® defoamers can quickly eliminate grinding foam;
5. To obtain optimal performance, Toynol^® additives must be added in water before resin and pigment;
6. Advise gradient test;
