Introduction:
Organic Bentonite 38 is a kind of traditional organic ammonium montmorillonite organoclay,which is applicable to aliphatic and aromatic system of low-medium polar solvent, such as mineral oil, paraffin oil, toluene, xylene, 200# solvent oil systems. This product is similar to Bentone 34.
Application:
38, as a kind of thickening, anti-sinkable, anti-sagging and thixotropy additive, is widely used in All solvent paint and coatings , sealing compounds, and cast coatings , grease, etc.
Usage:
38 can disperse at normal temperature. Pre-gel is suggested to make out of it and, added before grinding. High shearing equipments should be adopted so as to achieve the best dispersible effect.801-B can be dispersed completely with polar activator including: carbonic acid allethrin,methanol/water (95/5), ethanol/water (95/5)or acetone. The best dosage of polar activator can be changed according to different systems, usually 30-50% of the organoclay.
Dosage:
38’s dosage in the system is usually 0.5-2.0% (percentage in weight)
