Product Description
Bentonite can be divided into calcium grade, sodium grade, organic, active and other specifications
Applications:
1)Used for low,medium and high-polarity solvent system of the aliphatic, alkyl, aromatic hydrocarbon, or the mixture solvent with the aromatic hydrocarbon and the vinegar,ketone,ester,aether,alcohol,etc.and lubricating grease.
2)Used in adhesive,phenolic aldehyde,putty ash binder, acrylic painting, cast painting ,chlorinated rubber paint,ink (mineral oil), powder coating, asphalt primer, marine paint,antiseptic paint, etc.
Use methods:
:
1)Add painting and solvents mixed with stiring fastly
2)Add organic bentonite stiring for 10 minutes,make the bentonite fully wet.
3)Add polarity activator ,such as ethanol, carbinol ,etc,stir 5-10 minutes.
4) Add paintings etc, stir and scatter to the requiried fineness
5) Dilute to the necessary viscosity
Dosage:
According to different paintings,coatings,solvents'effect,generally adding 0.5%-2.0%,actual quantity can be confirmed by test.
