Product Overview

Nano Iron Oxide, also named nano Fe₃O₄ powder, CAS 1317-61-9, is high-purity superfine magnetic nanopowder designed as high-performance microwave absorbing filler.

With special nano-scale structure and intrinsic magnetic characteristics, the material generates efficient electromagnetic loss effect. When blended into industrial coatings, it endows coating systems with excellent electromagnetic wave absorption and EMI shielding functions. It can effectively absorb and attenuate electromagnetic radiation, restrain electromagnetic signal interference, and is an ideal functional additive for manufacturing wave-absorbing and anti-interference coating products.

Product Properties

The product is uniform black nanopowder with stable physical and chemical properties. Nano particle size ensures good dispersion compatibility with various resin systems for industrial coatings. It possesses favorable magnetic loss capacity, wide effective absorption frequency band, and stable wave absorbing performance. The material features weather resistance, and it will not easily degrade the basic mechanical properties of finished coatings after compounding.

Core Advantages

Excellent microwave absorption performance. Unique magnetic loss property enables effective attenuation of electromagnetic waves, achieving reliable EMI shielding effects for coatings.

Good compatibility with coating raw materials. Nano particles disperse evenly inside resin substrates, avoiding agglomeration and maintaining smooth surface of finished industrial coatings.

Wide frequency band adaptability. Works steadily for absorption of multiple-band electromagnetic waves, meeting diverse electromagnetic protection demands.

Stable weather resistance. Retains long-term wave absorbing function after coating curing, suitable for indoor and outdoor equipment protection coatings.

Easy processing. Can be directly mixed with solvent-based or water-based coating formulas without complicated pre-treatment procedures.

Main Applications

This nano iron oxide is used as microwave absorbing functional filler for different kinds of industrial coatings. It is widely applied in electromagnetic interference shielding coatings, radar wave absorbing coatings, electronic device anti-radiation coatings, communication equipment anti-interference coatings, and electromagnetic protection coatings for precision instruments.

Usage Guidance

Add nano iron oxide powder into coating formula during the grinding and dispersing stage. Match suitable dispersant to promote uniform distribution of nanoparticles. Adjust the addition proportion according to target electromagnetic shielding indicators.

Fully stir and grind the mixture to prevent particle aggregation. Test the wave absorbing performance of sample coatings to confirm the optimal dosage for specific projects.

Packing & Storage

Standard package adopts 25kg sealed kraft paper bags or plastic drums. Small sample packages can be supplied for formulation testing.

Seal and store the powder in cool, dry and ventilated environment. Prevent moisture absorption and particle agglomeration. Avoid long-term exposure under humid air. Keep separated from strong oxidants during storage and transportation. This product is classified as ordinary industrial chemical.
