Natural Mica Powder Filler for Resin, Epoxy and Composite Manufacturing
KosNature supplies natural muscovite mica powder as a functional mineral filler for epoxy resin, polyester resin, polyurethane resin, FRP, flooring compounds, 接着剤, sealants and composite materials.
Our mica powder with high purity, low impurity content, and stable performance.It can provide good dispersion performance for your resin systems.
Mica Powder for Resin
Our mica powder has thin particles, large particle diameter, and a good aspect ratio.
It can effectively form a physical barrier layer for your products.
Easy Dispersibility
High-quality wet-process products have a complete sheet-like structure, making them easy to disperse uniformly in the system and reducing flocculation.
Surface-modified products (such as silane treatment) can further improve compatibility with resins and dispersion efficiency.
Anti-Settling
The high aspect ratio sheet-like structure gives it excellent suspending properties, effectively delaying sedimentation and improving storage stability.
No Interference with Curing
Chemically inert, it does not participate in cross-linking reactions and has no adverse effects on the resin curing process at normal addition levels.
No Agglomeration (Easy Processing)
Pre-dispersion or masterbatch processes effectively prevent powder agglomeration, ensuring smooth operation.

FAQ Guide
Mica powder is widely used as a functional filler in coatings, plastics, and rubber.
It provides reinforcement, barrier properties, and insulation performance.s also commonly used as a pearlescent pigment in cosmetics and art resin to add luster.
さらに, it is used industrially in welding electrodes, roofing felt, and fireproof materials.
The common particle size range is 10–60 μm.
If you require surface smoothness and dense barrier performance, finer powder is recommended (such as <44 μm). If higher mechanical strength is required, coarser flakes can be selected (such as >100 μm).
Yes.However, particle size and surface treatment should be considered when selecting the product.
Mica powder has a high aspect ratio flake structure and excellent electrical insulation properties.
It can significantly improve resin rigidity, dimensional stability, and heat resistance.
At the same time, it is chemically inert and compatible with different systems.
Wet grinding is mainly carried out in water.
It better preserves the flake structure and produces products with higher aspect ratio, higher purity, and better performance.However, the cost is higher.Dry grinding is performed by direct mechanical grinding.
It has lower cost, but the structure is more easily damaged and the purity is less stable.
It is mainly used in applications with lower performance requirements.
