Zink oxide. This is an oxide zinc. Water insoluble, acids and strong base soluble. Zinc oxide, an important chemical additive, is commonly used for the manufacture of silicate products, plastics, rubbers, lubricants paints, ointments adhesives food, batteries and flame retardants. At room temperature, zinc oxide exhibits excellent luminescence properties and has a high band gap and exciton bound energy. You can use it in liquid crystal displays and thin film transistors as well light emitting diodes.
As a nano-material of zinc oxide, microparticles also became a part of related areas.

How is Zinc Oxide used?
1. It’s used mostly as a reinforcement agent, active agent or in rubber cable industry, coloring agent, filler of rubber and vulcanizing agents in Chloroprene.
2. Fine desulfurization in the chemical fertilizer sector.
3. Mainly used in white pigments for rubber vulcanizing activ agents, rubber catalysts, organic cats, desulfurizing substances, for xerographic print, pharmaceutical, and others.
4. It is used to desulphurize NH3, petroleum, and natural gas chemical materials gas.
5. Use it as a matrix in the analysis of reagents, reference agents, fluorescent agents, and other photosensitive data.
6. Useful for electronic wet copying, dry printing, laser facsimile communication and electrostatic recording on electronic computers.
7. It is used for special functions, such as plastic occupation and cleaning textiles.
8. This chemical is used extensively in the purification, deep desulfurization and extraction of materials for industrial purposes such as NH3, methanol, and hydrogen production.
9. It is used to make plaster and ointment.
10. Useful in the printing and papermaking industries, match making, coloring, and as a lightening agent. As a coloring agent in natural rubber, latex and rubber industries, it is also used as an active ingredient, reinforcement agent, and vulcanizing agent. You can also use it in production of zinc chromium, zinc yellow, and zinc carbonate. Additionally, it can also be used to produce feed additives such as zinc patching agents for feed processing, electronic laser data and phosphors.
11. White pigment. This pigment has a lower coloring power than Lithopone or titanium dioxide. This resin is used extensively in ABS resin (C8H8) n and epoxy resin as well as phenolic and NH3-based resins and PVC, paint, and ink coloring.

What role does Zinc oxide play in coatings?
1. As a White Pigment: Zinc dioxide is also called zinc white. Zinc oxide has a lower coloring power than titanium dioxide. This means that it can be used in situations where zinc dioxide is not required to change the color of titanium varnish. This makes it easy to weigh the paste and allows for an accurate adjustment. The color sensitivity can also be reduced.
2. This is a little-used method to increase the coating properties in epoxy resins with carboxyl functional bands.
Zinc oxide can be alkaline, reacts with carboxyl functional bands in epoxy resin to make zinc soap. The coating will improve flexibility and strength and it is lighter than titanium dioxide.

3. Promote the reaction between carboxyl and epoxy groups.
Epoxy resin / Polyester, Polyester / TGIC or other electrostatic materials: The catalytic reaction to epoxy is speeded up, dry-solidified, and the time of solidification is decreased.

4. It can be used as a filler for conductive functions.
Some industrial applications require the prevention of static electricity. This is because zinc oxide is an oxide of metal and has an electrical conductivity. Therefore, it’s used extensively as a conductive filler for architectural coatings.

5. It protects ultraviolet light.
Zinc dioxide is an inexpensive white light stabilizer. This has a high level of security protection, particularly for ultraviolet light between 240 and 380nm. This coating is used frequently in outdoor electrostatic powder. It has good UV shielding capabilities, which can extend the life expectancy of the product.

6. You can remove bacteria and mildew.
Zinc oxide can sterilize architectural coatings that are water-soluble and has strong germicidal abilities. Use it in the form of electrostatic powder to get rid mildew.

Why does rubber contain zinc oxide?
While zinc oxide makes up a tiny part of rubber compound production, it still plays an important part. Together, zinc oxide and the stearic acid make zinc soap. This improves zinc oxide’s solubility in rubber compound. It also forms a complex that contains an accelerator. This is a very powerful compound that reacts strongly with sulfur and forms a strong vulcanizing agents. This is the key to rubber production.
In rubber manufacturing, zinc oxide may also be used to improve rubber’s crosslinking density. Zinc oxide reacts to stearic to create Zn2++ sodium, which chelates to the side hanging rubber accelerator containing the sulfur. This makes the weak link in rubber stable, changes the cracking positions of sulfur bonds, allows rubber vulcanization, to form a shorter crosslinking bond, increase new crosslinking bond, and improves crosslinking density. Additionally, this can improve the thermal properties and aging of vulcanizates.
