Low viscosity paint crosslinking agent
Printing ink tends to be based on the viscosity of the viscosity of the liquid ink and the liquid ink which is very low in viscosity. The most common form of the paste ink is offset printing ink and screen printing ink. The printing ink, which is also called liquid ink, is very low in ink such as photogravure ink, flexible printing ink and press ink.
In the dry way of low viscosity inks (liquid ink), the ink drying is a dry way of ink by crosslinking reaction. At present, the printing industry is using more and more UV light curing ink and EB curing ink (electron beam solidification).
Crosslinking agent is one of the key components in the composition of the inks. The selection of the crosslinking agent, which affects the drying rate of the ink film after printing ink; In addition, the crosslinking agent also affects the viscosity of the ink system itself and the adhesive ability of the printing ink after printing. Third, crosslinking agent will also affect the printed ink film layer on the surface of the resistance, such as printed on the surface of the heat resistance, light resistance, water resistance and solvent resistance, etc.
To sum up, the crosslinking agent is an important component of printing ink and the printing of light oil formula to improve ink performance and improve the printing of ink. It must be carefully selected to give the ink or gloss coating different properties when choosing ink and polish.
Next, a brief introduction to the ink system and some of the crosslinking agents used in the gloss oil:? Oxidation of crosslinking agent: trace crosslinking agent used in the printing ink, unsaturated oil substances may be was a veteran in the ink system, unsaturated oil substances through crosslinking reaction of oxygen, so as to achieve printing ink or oil polish dry fixation. Oxidation series crosslinking agents are usually used in single sheets of paper offset inks and grease inks, which are not used in liquid ink.

Oxidation of crosslinking agent, however, also can use liquid inks, ink and can give the unique performance, good alkali resistance performance is the most prominent advantages of the crosslinking agent. This advantage is useful in some printing, such as soap packaging printing paper need to print on the surface of strong alkali resistance, the oxidation of crosslinking agent could play a role. Oxidized alkyd and epoxy resins meet some special applications in some printing.
Oxidative interlinking agents can be used with catalysts that promote oxidative reactions, or they may not be catalysts. Oxidation series crosslinking agent can give ink products superior adhesion and resistance.
Zinc ammonium carbonate and ammonium zirconium carbonate: these inorganic zinc ammonium carbonate and ammonium zirconium carbonate and carboxyl reaction, crosslinking agent and resin will produce zirconium zinc ionic bond or ionic bond, the ionic bond has a strong heat resistance and strong resistance to alcohol. Ammonium carbonate and ammonium carbonate are commonly used in water-based ink. The PH of the ink formula system is usually 9 or higher. If PH is below 9, the chemistry of the ink system becomes unstable.
Silane: silane is a stimulant to improve the viscosity of the ink, more specifically the alkyloxane. Silane can be added to the solvent ink or water-based ink, which can react with the resin's carboxylate. The chemical reaction time is a little longer.
In addition, a higher drying temperature is required after the addition of silane ink printing. Silane has good viscosity and anti-resistance properties, and these properties are well represented in ink products.
