Fenghong fine organic bentonite hfgel-127 has excellent thixotropy

  Hfgel-127 rheological additive is a newly developed organic ammonium modified smectite organic clay, which can be applied to paints, inks, lubricating esters and oily cosmetics in medium high polar solvent system
Hfgel-127 has good rheological properties in this kind of system
Hfgel-127 can adapt to various temperature conditions, form a good colloidal structure in the system, have excellent thixotropy and anti sedimentation effect, and strengthen the paint film at the same time
It can also be used as thickener of lubricating grease
The product is similar to bentone-27 and SD2

Product application:
Hfgel-127 is a new rheological additive, which is especially suitable for medium high polarity solvent systems, such as xylene butyl acetate, ethanol resin, xylene butanol and other solvent systems
It is applied to anti-corrosion paint, marine paint, industrial decoration paint, automobile primer, ink, lubricating ester, cosmetics and so on

 
usage method:
HFGEL-127 rheological additives are directly added to the grinding process of products
HFGEL-127 can be fully dispersed and activated under the shear force of grinding (or stirring) disperse pigments, and the pre gel can also be prepared according to traditional methods

1
Dosage:
The dosage of hfgel-127 rheological additive in paint depends on the thickening effect required by the system, the requirements for rheological property control and the precipitation degree of pigment
The typical dosage range is 0
5-1
5% of the paint amount
Generally, it can be tried according to the dosage of conventional organic soil and then optimized
Generally, its dosage is lower than that of conventional organic clay
