Introduction to Application of Titanium Dioxide in Coatings

Coatings are the largest user of titanium dioxide.

Titanium dioxide is a pigment used the most in coating industry (content of titanium dioxide in various coatings 10-35%)

Coatings are chemical materials. The modern coatings are becoming a type of multifunctional engineering materials gradually.

For the film formed, the coating is a semi-finished film product. The coating can only demonstrate its function after being used, i.e. being applied on the surface of the coated object.

The function of coating film can be concluded into three aspects: protection, decoration and special function.

The coating forms a film on the surface of the object after construction. Therefore, the composition of the coating contains the components needed for the completion of construction process and the formulation of film. The component that formulates the film is the most important and is necessary in every coating type. This component is called film forming matter. In the colorized film, the pigment is an important component in its composition. To complete the construction process, the coating contains solvent occasionally. For the need of construction and film performance, the coating contains auxiliaries sometimes. Therefore, the coating contains four components, i.e. film forming matter, pigment, solvent, and auxiliaries.

The coatings are usually classified into two types subject to the solvents used: oil paints and water-based paints.

Oil paints usually use aliphatic hydrocarbon, aromatic hydrocarbon, alcohol and other organic solvent.

Ware-based paints use water as the solvent.

The organic solvent in coatings will evaporate into the air during the film forming, resulting in air pollution and waste of resources. The organic matters released during the production and use of coating will cause heavy pollution to the air and are listed as one of the primary urban pollution sources following the cars currently. Therefore, the water-based paints using water as the solvent, due to its compatibility with and protection for the environment, are getting more and more attention as a substitution for solvent-based paint.

Water-based paints, powder paints and the high-solid content paints are the paints with the best prosperity.

Application of Titanium Dioxide Products in Printing Ink

Introduction to printing ink and the application of printing ink in titanium dioxide

About printing ink (I)

Printing ink is mainly made up of pigment, filling, and binder, additives (pigment and filling can be collectively called as coloring materials). Add proper amount of auxiliaries according to the requirements for printing performance. For example, the auxiliaries commonly used in water-based ink are PH value stabilizer, retarder, defoamer, reducer; the auxiliaries commonly used in oil-based ink are abrasion resistance agent, anti-gelling agent, viscosity reducer, etc.; mix, blend or wet grind after matching with certain ratio, and disperse evenly after repeated suppression to produce it.

About printing ink (II)

The manufacturing process of printing ink involves in colorimetry (color matching of printing ink), rheology (system viscosity of printing ink), colloid chemistry (system stability of printing ink), oil chemistry (selection of printing ink solvent), synthetic resin chemistry (flexibility of printing ink), pigment intermediate chemistry (matching of dyes and pigments), analytical chemistry (selection of system formula), photochemistry (UV printing ink), biochemistry (new biological ink) and content of other subjects, which needs comprehensive knowledge to fully master it.

Classification of Ink (I)

The classification of ink is not strict or clear enough in actual situations due to its miscellaneous varieties. Therefore, it is pretty difficult to classify them scientifically.
Generalized classification of ink shall be made subject to the printing plate, namely into relief printing plate ink, lithographic plate ink, gravure printing ink and screen printing ink. But this classification is limited by the principle, and cannot cover all practical situations. In recent years, the printing ink types are constantly increasing and more new designs appear. So if the classification is only made subject to the plate, there will be a great limitation.
Classification by drying type, such as UV printing ink, oxidation drying ink, penetration drying ink, evaporation drying ink, solidification drying ink, and etc.
Classification by purpose, such as book printing ink, tin printing ink, glass printing ink, plastic printing ink, and etc.
Classification by product features, such as security printing ink, high gloss ink, photosensitive ink, transparent printing ink, electrostatic printing ink. We also often hear alcohol (soluble) printing ink, water (soluble) printing ink. They are just called by their features. It can be seen that some names of the classified ink are out of date, such as rotary ink. And another example taken is lead printing ink, which is not as strict as it was before.
When we are talking about the classification of printing ink, we should first establish a concept of classification by plate, and then associate the other classification methods of drying type, product purpose and product features with each other. Only in this way will we establish a complete and systematic concept of classification.
