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:
- 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.
- 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.
- 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.
- 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.
