MT ST Rheological Additive
For solvent-based systems, improved performance of seed-resistant
MT ST is a very fine white rheological additive and forms a strong network structure in paint, printing ink and coatings, with excellent thixotropic property and good dispersion, providing excellent anti-sagging, anti-settling, thickening effect.
Applies to most of solvent-based or non-aqueous coating system.
3、Typical Physical Data
||·air-drying industrial finishes
||·texture and transparent varnish
||·chlorinated rubber coatings
||·caulks and mastic
||·coloring agents, cosmetic
||inorganically modified polyamide compounds
|Size Distribution (μm)
·Easy-to- disperse, can be incorporated into coatings system by simply mixing;
Allows higher incorporation temperatures commonly used for high-speed dispersion machine;
· Excellent thixotropy, anti-setting, thickening performance ;
·Without reducing water-resistance and weather-resistance of coatings;
·Does not normally react with system components such as pigments and resins
5、Levels Of Use And Incorporation
Levels of use: The optimum use levels of MT ST will depend on the system being formulated.In coating system, MT ST may vary from 0.2~0.8% by weight of the total formula.
Incorporation:Shear,controlled temperature and time are required for proper activation of MT ST.High-shear disc impellers, pearl, sand, ball or triple-roll mills should be used for MT ST.
１、Direct incorporation: Incorporation at the beginning of the dispersion. After pre-mixing the MT ST in a solvent/binder blend for about 5 minutes, other ingredients can be added and the system processed in the normal way.
２、Pre-gel: With 10% of the MT ST thixotropic additive, 10% butanol, or isopropanol, 80% of xylene by total formula weight for high-speed dispersion.Incorporate temperature should not be less than 40 ℃ and mixing temperature should not exceed 80 ℃, otherwise it will affect the use effect!
Levels of use : 3% -5% (in the form of pre-gel)
In the above temperature range, shear force as much as possible should be applied to MT ST in the disperse proces. Dispersed or abrasive, the stronger the better, sooner.
