Description

DEUTERON LE 50 is an additive designed to increase the conductivity of electrostatically sprayed lacquers. It is essentially a 50% solution of Tetraalkylammoniumethylsulphate in n-butanol. Here's a breakdown of its key details:

Chemical Description: Tetraalkylammoniumethylsulphate 50% solution in n-butanol.

Physical Data:

- Appearance: Light liquid
- Viscosity: Approximately 20 mPa·s
- Specific Weight: Approximately 0.89 g/cm³
- pH-Value: Approximately >7 (1% in distilled water)
- Flash Point: 35°C

Properties: DEUTERON LE 50 significantly reduces the electric resistance of organic solvents and their mixtures due to its cationic character and extreme polarity. It is soluble in all common lacquer solvent mixtures, sometimes appearing slightly cloudy.

Application: DEUTERON LE 50 finds use in various applications including air-drying primers and coatings, baking enamels, 2-component systems, and wood finishes.

Dosage: Depending on the polarity of the paint to be electrostatically sprayed, the dosage can range from 0.3% to 4% based on the total formulation. It's a highly effective anti-static agent, allowing for small amounts to be added while maintaining effectiveness. This is crucial to avoid detrimental effects on water resistance or reduction of anti-corrosion properties.

Processing: It can be added at any time during production and to the final product with a simple stirrer.

Storage Conditions: DEUTERON LE 50 can be stored in its original tightly closed containers for at least 24 months at room temperature.

Package Sizes: Available in steel hobbock/hoop (25 kg net) and steel drum (185 kg net).

Safety Regulations: Classified as a dangerous product according to regulations and requires labeling. Detailed safety information is available in the safety data sheet provided by the manufacturer.

DEUTERON LE 50 is part of the range of conductivity agents offered by DEUTERON GmbH, serving the needs of the coatings industry.
