German technical background VOK®-NALZIN FA 179 Corrosion inhibitor

Introduction:

VOK®-NALZIN FA 179 can be used as a corrosion inhibitor for water-soluble coatings to prevent the formation of "flash corrosion", and can also be used as an inhibitor for tank corrosion. Because it can be emulsified in water, it can also be used as a temporary corrosion inhibitor.

Physical characteristics:

Appearance characteristics: transparent liquid

PH value, 5% dissolved in water: 8.0-9.0

Density at 20 ℃: about 1080Kg/m3

Viscosity at 20 ℃: zui is 250 mPa. s

Color: zui Dawei 12 Gardner

Solubility: soluble in water

Flash point (ASTM D 65):>62 ℃

Composition: Chelated zinc compound dissolved in various solvent mixtures

Application and characteristics:

VOK®-NALZIN FA 179 can be used on various types of water-diluted coatings, such as water-diluted alkyd resin coatings, acrylic resin, epoxy resin and coating dispersions.

VOK®-NALZIN FA 179 prevents the formation of flash corrosion, that is, the corrosion caused by water-soluble coating during drying on iron-containing substrate.

VOK®- NALZIN FA 179 contributes to the corrosion resistance of dry paint film and prevents tank corrosion during storage.

It can also be used as a temporary preservative for metal surfaces. For this purpose, 2% VOK can be sprayed on the metal surface ®- NALZIN FA 179 lotion. This method is recommended when VOK is not added to the paint ®- NALZIN FA 179, which can prevent early corrosion after construction.

characteristic

It is based on organic zinc chelate and has low nitrite content.

It shows strong affinity to iron-containing substrate to prevent flash corrosion.

Although it is water-soluble, it can be changed into insoluble or soluble zinc chelates during drying.

Water sensitivity decreased.

A passivation layer is formed to prevent corrosion after the paint film is dried.

It can be used as corrosion inhibitor in the tank.

Improved weather resistance.

consumption:

In order to prevent the formation of flash corrosion, 1.0-0.5% of total paint shall be added at the final stage of paint production VOK®-NALZIN FA 179。

To prevent corrosion in the tank, with concentration of 0.1-0.3% can be used VOK®-NALZIN FA 179。
