S309 Organic Bentonite Thickening Rheological Agent

1. Quality Specification

Appearance: Light yellow powder

Moisture content(105℃,2hrs): ≤3.5%

Granularity (<76μm or200mesh): ≥95%

Fineness dispersion(no mill):≤60μm

Density:1.6 g/cm³

2. Characteristics and Application

S309 is made through special process of modifying. This organoclay has super dispersing property and high thixotropic property, applicable to low, middle and high polar solvent systems.

Disperse at high speed shear without polar activator in middle and high polar solvent systems, while in low polar solvent systems, adding a small amount of polar activator can reach better dispersing effect. In suitable systems, the fineness dispersion can be less than 5μm and it appears super thixotropic property and anti-flowing property. S309 can be added at any step. Then, according to different solvent systems, polar activator dosage is 20%-30% of organoclay or not needed.

It is with dispersion at high speed or by mill. Usually, the dosage in paints is 0.2-1.5%. It is applicable in epoxy paints, anti-corrosion paints,  high temperature lubricating greases, wood  paints, high-grade paints and inks,etc.

3. Packaging and Storage

Kraft bag interior with PE, or valve bags are used. The normal package is 25±0.25kg/bag, or according to customer demands. Keep it in dry places with temperatures of 0℃~30℃. The quality guarantee period is 24months.
