Zhejiang Fenghong hfgel-140f organic bentonite without activating thickening rheological additives

  Hfgel-140f rheological additive is a new easily dispersed and self activated organic ammonium modified smectite organic clay
It is a rheological additive for paints and inks in medium high polar solvent systems such as aromatics, esters and ketones
It is used in medium high polar solvent systems such as xylene esters (such as butyl acetate), xylene ketones (such as cyclohexanone) and xylene butanol, It can be self activated and dispersed without activator
In the low polar solvent system of aliphatic hydrocarbons such as 200 solvent oil and white oil (mineral alcohol), activator shall be added to help dispersion (activator such as 95% ethanol, 30-40% of the weight of organic soil)
The products are similar to bentone-sd2, Claytone APA and tixogel-mp250

Product application:
Hfgel-140f is a kind of easily dispersed and broad-spectrum rheological additive, which is especially suitable for medium high polarity solvent systems, such as xylene, xylene butyl acetate, xylene cyclohexanone and other solvent systems, as well as anti-corrosion paint, marine paint, industrial decoration paint, automobile primer, binder and sealing materials

 
usage method:
Hfgel-140f rheological additive is generally directly added to the grinding process of product processing
Under the shear force of grinding (or stirring) dispersed pigment, hfgel-140f can be fully dispersed and activated

1
Dosage:
The dosage of hfgel-140f rheological additive in paint depends on the thickening effect, rheological property control requirements and pigment precipitation degree required by the system
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

2
General usage:
(1) Add resin / solvent;
(2) Add hfgel-140f additive and stir at high speed for 10-20 minutes;
(3) If the solvent is 200 solvent oil, white oil and other aliphatic hydrocarbon low polar solvents, add 30-40% polar activator of organic soil (such as 95% ethanol) and stir at high speed for 10-20 minutes;
(4) Add wetting agent and pigment, grind and disperse (stirring, ball milling, sand grinding) to the required fineness;
(5) Add other materials in the formula and continue to disperse until uniform
