Applications in coatings:

Flame retardant coatings: Aluminum hydroxide can be used as a flame retardant in coatings to improve the flame retardant properties of the coating. This is useful in applications where the coated surface needs to be protected from fire or high temperature environments.
Optical coatings: Aluminum hydroxide particles can be used to prepare optical coatings for reflecting and refracting light, such as mirrors, optical filters, etc.
Applications in industrial paper:

Flame-retardant paper:

In some special industrial applications, paper with flame-retardant properties is required to improve fire safety. Aluminum hydroxide can be added to the manufacturing process of industrial paper to enhance its flame retardant properties.

Filler: 

Aluminum hydroxide can be used as a filler in industrial paper to improve the strength and texture of the paper. This helps create stronger and higher quality industrial paper suitable for packaging, printing and other uses.
In both areas, aluminum hydroxide is often used as a functional additive to improve the properties of materials. Its application can vary depending on the specific requirements and the type of coating or industrial paper being prepared. The addition of aluminum hydroxide often enhances a material’s fire resistance, mechanical properties, optical properties or texture, making it suitable for a variety of industrial applications.
