Charging Additive  KC3010

To share:

The main chemical composition of the charging additives is fatty acids and quaternary ammonium salt complexation. One is the fatty acid compounds, the melting point of the powder is at 67℃~70℃, and it is white powder, it is mainly through proton exchange occurs the charge transfer, and it can change the surface resistivity of the powder coating. Another is the heat resistance quaternary ammonium salts that based ionic surfactant, it is white or light yellow powder, the use of hydrophilic groups in the powder coating surface can absorb moisture from the air to form pro-dielectric film or rely protic reduced surface resistance.

The chemical charging additives of zhihua is based on the above two kinds of main component to compound, it can overcome the recessed corners and other parts difficultly powdering problem by electrostatic shielding, Meanwhile the leak is faster than a large number of surface accumulation charge, it can reduce the electrostatic repulsion and bounce caused big ripples orange peel, and it can make the coating surface smoothly.

1. Technical parameters

Ø  Appearance: white powder

Ø  Content: ≥99%

Ø  Thermal decomposition temperature:≥300℃

Ø  Volatile matter: ≤0.15%

2. Product feature

Ø  It can prevent static electricity to adsorp dust in the air on the products.

Ø  It can prevent static electricity to make adverse consequences in the processing, such as adhesion inequality.

Ø  It plays a surface regulatory role of the coating appearance, it can promote leveling, and the coating has a good printing.

Ø  It has a suitable compatibility with the resin. If the compatibility is too large, the charging additives have a slow migration on the powder surface to form antistatic layer; if the compatibility is too small, the charging additives have a fast migration to change the appearance of the powder coating.

3. Dosage

This product is used by added to involve in extrusion, the use level is 0.3% by weight based on total formula. Please accord to the test to determine the specific amount.

4. Packaging and storage   

Packaging with PE lined Kraft paper bags. Net weight 25kg per bag. Sealed packaging, storing in a cool and dry place, reasonable storage shelf life of this product is at least 2 years.
