1, this product belongs to class II corrosive chemicals, use with protective glasses and acid-proof gloves, once splashed on the skin, rinse with plenty of water.
2, suitable for use in the medium of PH value 2-7 or with.
3, Avoid adding sulfide, and do not contact with oxidizing and reducing substances.
Take the OT DLPI-46 (KR-46) produced by Ken rich in the United States as an example. Its chemical composition is bis(dilauryl phosphite) complex tetraoctyl titanium oxide, and the structural formula is (CH jrO): Ti·[ P(OH) (OC: Hz s) ala, good water resistance, can be used in solvent-based or water-based coatings. It can be dissolved in organic solvents such as dioctyl phthalate, toluene, xylene and gasoline to coat pigments and fillers or directly used in solvent-based coatings; it can also be used in hydrophilic cosolvents such as AMP-95 (2-Amino-2-methylpropanol), etc., disperse it in water or direct high-speed grinding method to emulsify and disperse it in water, coat pigments and fillers, or directly use it in water-based paint.
According to the literature [2~4], the application of KR-46 in coatings has the functions of anti-rust, corrosion resistance, catalytic curing and lowering the baking temperature. It can be genetically modified wax summarized into the following aspects of application performance:
Improve the dispersion of most pigments and fillers in polyvinyl acetate latex paint, the amount of filling and the friction resistance of the coating, such as the improvement of chrome green in alkyd resin, colored quartz in epoxy resin and barite powder from 3M Dispersibility in chlorinated rubber.
Significantly reduce the viscosity of most pigments and fillers in acid anhydride cured or amine cured epoxy resin systems, but it is not suitable for amide cured epoxy resins.
Improve the adhesion of melamine resin to steel, iron, aluminum, tin, brass and other metals, glass and inorganic materials, and improve the adhesion of polyester, polyurethane, and epoxy resin to mild steel.
Improve the filling amount and coating gloss of most pigments and fillers in saturated polyester and unsaturated polyester. Improve the wear resistance of the titanium dioxide-containing internal acrylic resin coating.
