Used as a reinforcing and extending agent in paints and coatings, dry mica powder improves durability, weather resistance, corrosion resistance, and water barrier properties. It is commonly used in rust-proof paints and structural steel coatings.

It is added to plastics to enhance stiffness, strength, heat resistance, and dimensional stability while reducing shrinkage, making it suitable for automotive parts and electrical equipment.

In cosmetics and skincare products, it provides a natural shimmer, improves texture, adhesion, and smooth feel in items like foundations, powders, blush, and eyeshadow.

Also utilized in construction materials such as cement and asphalt to reduce cracking and improve strength. In rubber, it enhances tear resistance. In ceramics, it aids forming and reduces cracking during firing.

Common in welding rod coatings, where it acts as a slag conditioner and arc stabilizer. Its electrical insulation and heat resistance make it suitable for use in electronics and thermal insulation applications.
