Product Details
The using method of organic bentonite for paints.
Pre-gel method
The usage is more suitable for poor wettability resin systems and non-thixotropic grinding pigment. Ingredient: solvent 87%, organic bentonite 8-10%,polar activator (95%alcohol or 95%methanol)3-4%.
Process:
Add organic bentonite into solvent, stir the mixture for 10mins,make it be fully dispersed.
Add polar activator and stir 5mins to lrt it be fully dispersed and inflated. If needed,1%-2%surfactant can be added to the pre-gel for lower viscosity.
Instructions for use
1.For poor wetting epoxy resin,polyester,short oil alkyd resin and acrylic rosin with surfactant,and thixotropic grinding pigment,the process can be used as follows:
●A.Resin blend with solvent
●B.Add organic bentonite pre-gel for dispersion.
●C.Add the pigments and fillers,disperse with high shear for a few minutes.
●D.Complete dilution
2.For poor wetting resin system and non-thixotropic pigment,the process can be used as follows:
●A.Resin blend with solvent
●B.Add appropriate surfactant if possible.
●C.Add the pigments and fillers,disperse with high shear for a few minutes to the right fineness.
●D.Add organic bentonite pre-gel for dispersion.
●E.Complete dilution
