TT-935 hydrophobically modified alkali soluble emulsion thickener can be used as the preferred thickener or synergistic thickener for waterborne coatings. At relatively low dosage, TT-935 can effectively improve the medium shear (Kreb Stormer) viscosity.Compared with the medium and high molecular weight cellulose thickener, the fluidity and leveling performance of the coatings were improved. Adding a small amount of surfactant or ethylene glycol ether cosolvent to reduce the low shear viscosity

TT-935 can be used in exterior wall coatings, but as the product contains anionic structure, we suggest that formulators should pay attention to minimizing the possibility of foaming. We recommend SCT-275 non-ionic polyurethane rheological modifier for higher water resistance. The following benefits can be obtained by using TT-935 alone or in combination with other thickeners: Improving flow and leveling Improving Spatter ResistanceStability of antimicrobial enzymes Reducing the cost of raw materials
physical characteristics
The following are typical data, but should not be considered as specifications:
Appearance: Milky white liquid
Solid content, by weight (%): 30.0
Density (g/ml): 1.058
Brinell Viscosity (Lipper, LVT, 1# Rotor, 60 rpm, 25 C) < 200
PH value: 2.8
Chemical type: anion
Usage
- adjust the pH value of the coating with ammonia water to 8-9.
- Dilute the water of ALESHUN TT-935 in a ratio of 1:1.
- Under the condition of low-speed stirring, diluted ACRYSOL TT-935 was added slowly, and the pH value of the coating was adjusted by ammonia water to keep it at 8-9 all the time.
- Measure the change of paint viscosity while stirring, stop adding thickener after reaching the prescribed viscosity.
