what is Rheology Organoclay for Lubricating Grease

GDGEL-283B ORGANOCLAY RHEOLOGICAL ADDITIVE

Organophilic Clay Description：

GDGEL-283B is an organo clay (modified montmorillonite), designed especially for use in solvent based system including intermediate and low polarity polarity range organic liquid. It is an improved grade of GDGEL-283B. It is more fine, and easier to be dispersed compared with GDGEL-283.

Solvent Based Rheological Additives Properties：

Composition                              Organic derivative of a montmorillonite clay

Appearance                               Fine powder, light yellow

Moisture content (105℃,2hr)         ≤3.5%

Loss on ignition (1000℃)              40% Max

Bulk density                                 0.46g/cm3

Fineness (<74μm, %)                    ≥98%

Solvent Compatible Bentonite Application:

● Transparent coatings

● Lubricant Grease, ink, sealant

● Nano-composite

● Replacement of fumed silica

● Cosmetic

Rheology Modifiers Thickeners Using:

GDGEL-283B disperses under high shear and requires a polar activator (30%~40%)  for best efficiency. Heat is not required to obtain good dispersion. Addition levels are typically in 0.2%~2.0%. Polar activator (95% Ethanol or 95% Methanol) is needed. Normally addition level of polar activator is recommended to be 30%~40% of GDGEL-283B in weight.

International Countertypes:

Bentone®38, Claytone® 40

We believe that good quality and service make us to run faster and longer.

How to choose the suitable Organoclay for Solvent Based Paints/Coatings/Inks/Lubricant Grease?

The following 5 points can help us recommend the suitable grades.

1.      The solvent polarity (low, middle, high) and the percent of solvent composition they are using.

2.      Do they need to make pre-gel with addition of polar activator or add with dry powder.

  Our easy dispersing grade can be added directly, but some grades need to add polar activator and make gel.

3.      what’s resin system? The Bentonite should be used in unsaturated resin or epoxy resin system or the others?

4.      what is your purpose of organoclay when used in paint, ink, lubricant grease? Is it anti-sagging ability or anti-settling ability?

5.      Do they make finish or primer paint? Do they have the special requirement of transparency, color, matting capability etc.?
