ORGANOCLAY BENTONITE SOLVENT BASED RHEOLOGICAL ADDITIVE
CP Series Organoclay Use Methods
CP series organoclay is made by excellent bentonite with the processing of highly purified, modified and oil exchange into organic covering additives, it is a sheet structure product, if you want the organic bentonite to play a better performance, you need
to separate its sheet-structure as much as possible. This process usually needs to be provided with mechanical energy, chemical
Energy and heat energy.
Dry powder method:
Dry powder method is that add the dry powder directly into the system during the production process.It doesn’t need the polar activator, such as CP-10, CP-APA, CP-MP10 ect
Pre-gel method :
For poor wettability resin systems (such as epoxy, polyester, short oil alkyd resin etc.) it is better to use CP series organoclay by pre gel.
(1) Composed of pre gel: solvent 87%， organoclay bentonite 8-10%， polar activator 3-4 %.
2）Preparation of pre gel: solvent and organic bentonite(mixed 10min, fully wettability),then add the polar activator (stirring for 5 min,full expansion).
Organoclay bentonite must have enough moisture to develop into a network structure pre gel, the water molecules forming a
bridge for the network structure, so the organoclay bentonite should not be too dry, the general moisture content should be around 3.5%， polar additives should not use anhydrous, the suitable content of the polar additives is appropriate 95% (the moisture is 5%).
The polar additive can help the sheet-layer structure Organoclay bentonite easily form a layer-sheet structure, thus formed a thixotropic gel,polar additives such as ethanol, methanol, acetone, propylene carbonate, the add amount of polar additives is generally 30%-50% of the organoclay bentonite.
