AQUACER 531

AQUACER 531 is a versatile wax emulsion based on a modified polyethylene (PE) foundation, primarily used to enhance the surface properties of various aqueous coatings, printing inks, dry lubricants, and adhesives. Here's a breakdown of its characteristics and applications:

Composition: It comprises a non-ionic emulsion of a modified polyethylene wax.

Typical Properties:

• pH value: 3.5
• Non-volatile matter: 45% after 60 minutes at 125°C
• Carrier: Water
• Melting point: 125°C (wax content)
• Viscosity: 125 mPa·s at 20°C (D=400/s)

Storage and Transportation: It should be stored and transported within a temperature range of 5°C to 35°C, and it's advised to stir before use.

Applications:

1. Coatings Industry:
   • Special Features and Benefits: Enhances scratch resistance in aqueous coatings, increases abrasion resistance in printing inks, improves surface slip, and blocks resistance.
   • Recommended Use: Suitable for architectural coatings and printing inks/overprint varnishes.
2. Adhesives and Sealants:
   • Special Features and Benefits: Acts as an anti-blocking additive in hot-melt adhesives during underwater pelletizing, producing free-flowing and non-sticking granulated material.
   • Recommended Use: Added directly to the cooling water during the manufacturing process.
3. Thermoplastics:
   • Special Features and Benefits: Prevents compaction and caking of thermoplastic granulated material during underwater pelletizing, resulting in non-sticking and free-flowing granules.
   • Recommended Use: Added directly to the circuit water during underwater pelletizing.
4. Lubricants and Metal Processing:
   • Special Features and Benefits: Used in dry lubricants and anti-friction coatings to adjust the coefficient of friction (CoF) on metallic substrates, forming a uniform wax layer for low CoF.
   • Recommended Use: Can be used alone or with other aqueous binders in dry lubricants, anti-friction coatings, and surface sealers for metal components.

Recommended Levels: Vary based on application:

• For coatings and printing inks: 2–5% additive based on total formulation.
• For adhesives, thermoplastics, and lubricants: Ranges from 0.2% to 10% based on specific application requirements.

Incorporation and Processing Instructions:

• For coatings and printing inks: Preferably incorporated with a low shear rate at the end of the production process.
• For adhesives, thermoplastics, and lubricants: Added directly to the respective processes.

In summary, AQUACER 531 offers multiple benefits across various industries, including enhanced surface properties, anti-blocking capabilities, and improved lubrication, making it a versatile additive for different manufacturing processes.
