Structural formula:

Physical and chemical properties: This product is a dark yellow or dark orange red viscous liquid, flash point 160 ℃, density ρ (20 ℃): 1.101, refractive index n 20 ℃ 1.471, decomposition temperature 210 ℃. Soluble in isopropyl alcohol, xylene, toluene, insoluble in water. This product is a non-toxic and non-corrosive liquid. The oral poisoning amount of white mice is LD 50 10g/kg (reference value: table salt LD 50 3.8g/kg)

Application areas: plastic products, rubber products, adhesives, fiberglass products, paints, inks, ointments, magnetic materials, waterproof materials, composite flame retardants, etc.

Application object:

1. Matrix resin: PE, PP, PS, PC, AS, ABS, PVC, SBS, polyester, polyether, polyurethane, polyamide, polycarbonate and other thermoplastic, thermosetting resins and other elastomers.
2. Inorganic fillers: CaCO₃, MgCO₃, BaSO₄, CaSO₄, MgO, Al(OH)₃, talc powder, mica powder, lithopone powder, titanium dioxide, wollastonite powder, pyrophyllite powder, sepiolite powder, Carbon black, clay, bentonite, aluminum smelting red mud, iron red, chrome yellow, titanium cyanine blue, antimony trioxide, ammonium polyphosphate, zinc metaborate, etc.

Product Features:

1. This product is a chelating titanate coupling agent, suitable for processing high humidity filler. Such as precipitated white carbon black, clay, talc, silicate, carbon black, glass fiber, etc.
2. This product can significantly increase the dispersion, anti-settling and storage stability of pigments such as carbon black, iron red, medium chrome yellow, and titanium cyanine blue in the organic matrix, shorten the grinding time and the number of channels, improve Paint film adhesion, appearance, corrosion resistance, enhanced adhesion and catalytic curing functions (see "Coating Dispersion Coupling Agent" for details).
3. Chelating titanate coupling agent has better viscosity reduction effect than monoalkoxy type, its addition ratio is preferably 1.0-1.2%, it will continue to increase, the effect is not obvious.
4. This product has obvious effect in rubber products, such as increasing tensile strength, tear strength, elongation and aging resistance.
5. This product can greatly increase the filling amount of inorganic filler in resin (plastic, rubber, paint and other composite products), significantly improve the physical and mechanical properties such as tensile strength, impact strength, elongation at break, and reduce the system viscosity , Improve processing performance, reduce, energy consumption and production costs.
