First, summary
The product is a new type of chelating phosphate coupling agent quaternary ammonium salt, and it is the best high-performance
water-soluble titanate coupling agent at present in our country. Its applied range is wide and has an obvious effect.
Second, composition
It is a kind of more reactive type chelate titanate coupling agent which is similar to American KR-238S.
Third, technical indexes
Density: D25≥1.008g / c
Viscosity: 850-950 mpa.s
Flashing point: (open)≥100℃
Refractive index: 1.487±0.002
PH: (test paper)7±0.5
Forth, dosage
0.5-2.5% of the weight of pigments, fillers or magnetic powders. Recommended dosage is 1-1.5%.
And the best dosage depends on experiment.
Fifth, application range
Magnetic material: magnetic powder, magnetic ink, magnetic tape, magnetic disc, magnetism and so on;
Magnetic plastic, magnetic rubber, magnetic coatings, magnetic ink, waterproof paint or waterborne coatings, dye, filler modification.
Sixth, characters
It can make active calcium have high padding in rubber and plastic and the performance is excellent;
It can increase the padding of magnetic powder to improve magnetic intensity;
It is benefit to the affinity between magnetic powder, pigments, or fillers and carrier to improve adhesive force and intensity;
It can be mixed with water under any proportion. It is not only appropriate for waterborne products but also for oil soluble products.
Seventh, usages
Diluted by solvent ≥1:1, the product needs to be sprayed uniformly in the pigments or fillers which are stirred at a high speed
(the product doesn’t need heating from outside ). It needs stirring for 5-15 minutes (the concrete time depends on rotational speed and dispersion effect ), then it can be discharged for reserve or
be added with other additives or carriers.
If it is used to grind, the diluted product should be added before grinding. Only adopt the above method will make grinding
more effective.
What’s more, it also can be diluted and soaked by water. Then it can be dehydrated or not dehydrated to be the solvent of the
formular. To produce pigments and fillers in a wetting way, it can be added in the productive period to take part in the reaction.
Eight, attentions
Pigments or fillers which are disposed at a high speed, heat dissipation should be noticed if they are discharged for reserve.
The product has a high viscosity (especially in winter), so before using, it should be heated in water bath. When the
temperature>50℃, the viscosity will descend quickly.
The product should be stored in a mothballed place under normal temperature. Shelf life is 3 years.
