CH-39
Ingredients: modified polyesterAcid value: ≤35mgKOH/gPackaging: 200 kg, wide-open iron drum packagingEffective ingredients: 100%State: brown viscous liquidDensity: 0.99g/cm3Flash point: ≥185℃Shelf life: 2 yearsA. Used in solvent-based coatings (vehicle paints, industrial coatings, high-solid coatings, general color pastes) as well as solvent-based inks and ultraviolet (UV) curing inks to improve pigment dispersibility and tinting power and rheological properties.B. Used for surface treatment of organic or inorganic pigments to improve pigment dispersibility, tinting power and solvent resistance, improve pigment fluidity and improve coloring effect.A. When used in inks and coatings, CH-39 can be dissolved in the resin solution, stirred evenly and then added to the pigment for grinding. The dosage of CH-39 is 1-5% of the dry weight of inorganic pigments and 5-15% of the weight of organic pigments and carbon black.B. When used for surface treatment of organic pigments, CH-39 can be slurried with pigment filter cakes, or added in the form of emulsion or solution before filtering the pigment, or CH-39 can be ground together with the crude pigment to participate in its pigment transformation process. The dosage of CH-39 is 2-5% of the dry weight of the pigment.
