What Is Zinc Oxide Powder?
Zinc oxide is a highly stable substance that can remain stable in harsh environments such as high temperature, high pressure, strong acid, strong alkali, etc. Zinc oxide powder is usually white or slightly yellowish. It is used in a variety of manufacturing processes: rubber, plastics, ceramics, glass, cement, lubricants, paints, ointments, adhesives, sealants, pigments, food, batteries, ferrites, flame retardants, and first aid tape.

How to Use Zinc Oxide Powder on the Face?
Zinc oxide has been found to have the following uses and benefits:
- It helps reduce skin inflammation associated with rashes, allergies, or irritation (including diaper rash);
- Provides broad-spectrum sun protection against burns (including photosensitive skin);
- Prevents skin cancer/tumors (basal cell carcinoma);
- Promotes wound healing and prevents bacterial infections;
- Helps with the recovery of burns and damaged tissue;
- It helps treat acne breakouts;
- Keeps moisture locked in dry skin;
- Reduces dandruff;
- Treats warts;
- Relieves inflammatory skin conditions (including rosacea);
- Treats pigment disorders (melasma);
- Prevents skin aging;
- Promotes collagen synthesis and the formation of new connective tissue;
Since zinc oxide is not water-soluble, it needs to be combined with a carrier agent to be most effective. It is often added to topical solutions such as makeup (especially skin foundations), mineral sunscreens, salves or balms, and moisturizers. Some lotions or creams contain zinc oxide so that the oily substance penetrates the skin. The zinc forms a barrier over them, locking moisture in place. Because zinc is a mineral, it can adhere to the skin and reflect sunlight by scattering UV rays. Therefore, zinc oxide is called a "physical barrier substance" rather than a "chemical substance." Due to this scattering ability, most commercial chemical sunscreens usually also add at least a small amount of zinc oxide. Zinc oxide is often used in combination with other anti-inflammatory or antibacterial zinc substances, including antioxidants, zinc gluconate, or zinc sulfate, and sometimes in combination with antibacterial agents to treat acne.
What is the Role of Zinc Oxide Powder in Coatings?
Here are six functions of zinc oxide in paint:
- As a white pigment and as a filler: Zinc oxide is a white pigment, also called zinc white. Because its tinting power is smaller than that of titanium dioxide, when titanium dioxide varnish is needed for coloring, zinc oxide can be used in larger quantities when replacing titanium dioxide. It makes the color paste easy to weigh, easy to adjust accurately, and reduces color sensitivity.
- A small amount is used in epoxy resins containing carboxyl functional groups to improve the properties of the coating: Zinc oxide is alkaline and can react with the carboxyl functional groups in epoxy resins to form zinc soaps to improve the flexibility and strength of the coating, and the coating is cleaner than titanium dioxide as a color paste.
- Promote the reaction between epoxy and carboxyl groups: In electrostatic powders such as epoxy resin/polyester, polyester/TGIC, etc., it makes the epoxy reaction carboxyl reaction faster, catalyzes the drying reaction, and reduces the solidification time.
- As a conductive functional filler: In some industrial applications, anti-static or conductive static electricity is required. Zinc oxide, as a metal oxide, has a certain conductivity, so it is widely used as a conductive filler in this type of architectural coating.
- Has the function of shielding ultraviolet light: Zinc oxide is a reasonable and low-cost white light stabilizer. In particular, it has good safety protection capabilities for UV light in the range of 240-380nm. It is often used in electrostatic powders, especially for outdoor electrostatic powders. It has good ultraviolet light shielding capabilities, which can increase the service life of the coating.
- Has the function of removing mold and bacteria: Zinc oxide has a strong sterilization ability and is used for sterilization in water-soluble and other architectural coatings. It also has the effect of removing mold when used in electrostatic powders.
