Lithium Battery Applications
In the lithium battery industry, CY-QX20 fumed nano alumina is applied as a coating on battery separators to significantly enhance their high-temperature resistance and safety, effectively preventing thermal shrinkage and short circuits. Additionally, as an additive for lithium battery anode materials, it improves electrical conductivity and reversible discharge capacity. When used for negative electrode coating, it effectively enhances temperature resistance and overall safety performance.
Powder Coating Applications
CY-QX20 is an ideal additive for tribo-charging powder coating formulations. Whether used in epoxy-polyester hybrids, polyester-TGIC, or other resin systems, it delivers an excellent combination of flowability and charge characteristics. It improves powder bulkiness, reduces caking, enhances abrasion resistance, promotes powder flow during spraying, and increases powder transfer efficiency. It also performs exceptionally well as a thermal and radiation protection agent in coil coatings.
Industrial Additives
As a flow promoter, CY-QX20 enhances anti-blocking performance in PET films. It also serves as a key component in protective and adhesive layers for fluorescent tubes, light bulbs, and eco-friendly powder coatings.
Inkjet Paper Coatings
CY-QX20 fumed alumina is widely used in high-quality inkjet paper coatings, imparting excellent gloss and superior print quality to the paper surface.
