The product is a new kind of chelate phosphate acid titanate coupling agent quaternary ammonium salt, which is the best water-solubility titanate coupling agent in China and widely used. The effect of it is obvious, especially for magnetic and particles. It is also best assistant for producing active calcium (light calcium).
Appearance
Brow viscous liquid
Component
It is a kind of chelate phosphate acid titanate coupling agent which contains many active and component and similar to KR-238s made by Kenrich Chemical Company,USA.

Dosage
0.5~2.5% of the pigments, filler or magnet particle’s weight. And recommended volume is 1~15% of the pigments, filler or magnet particle’s weight. And the best dosage should be determined by experiments before use.
Range of Application
• It can be used in all kinds of magnetic material industry such as magnet particles, magnetic ink, magnetic band, magnetic disk, and magnetic core.
• It can be used in magnetic material industry such as magnetic plastic, magnetic rubber, magnetic coating, magnetic ink etc.
• It can also be used to improve the property of water proof or water soluble coating, fuel, filler.
• Producing of light calcium.
Feature
• It can improve the quality of the filling of the active calcium in the rubber, plastic, and improve the property of products.
• It can increase the filling quantity of magnetic particle and improve the quality of magnetic property.
• It can improve the avidity of magnetic particle, pigments or filler with carrier. At the same time, it can increase the adhesion and strength of the product.
• It can be dissolved in water at any rate, so it can not only be used in water-solubility product, also in oil-solubility product.
• This product can be stored for a long period and better than all other coupling agent.
Usage
Spray the coupling agent (diluted by solvent (1:1)) into pigment or filler in high speed mixer (no heat from outside), after agitating 5~15 minutes (the time of agitating depends on the speed of agitating and the effect of dispersion), discharge the material or add other auxiliary agent and carrier.
In the case of grinding process, it may be added before grinding, which is diluted by solvent.
It is permitted to dilute and immerse the material with water, then remove moisture or take water as solvent in the formulation. The coupling agent can also be added to the product to react during producing for moisture, producing pigments and filler.
In the process of producing active calcium, the coupling agent can be added during hydrolytic decomposition and then take part in charring.
Choice of solvent
Liquid wax (white oil), solvent oil or machine oil, isopropyl alcohol, alcohol, water etc.
Caution
For the pigment treated by high-speed mixer, please notice the heat elimination in the case of discharge.
If the product is found to be high viscous (especially in winter), you can heat it up under water bath and use it
If the temperature of the material is higher than 50?, the viscosity of it will decline.
Validity for three years from delivery date under encapsulation packing on the common temperature.
