ADDITOL® XL 203 is a silicone-containing cationic antifloating, wetting, and dispersing agent primarily used in paint systems to prevent the floating of titanium dioxide and enhance pigment dispersion. Here's a breakdown of its key features, specifications, and suggested uses:
Type:
Silicone-containing cationic antifloating, wetting, and dispersing agent.
Form of Delivery (f.o.d.):
Active substance approx. 40%.
Product Data:
- Dynamic Viscosity (100 1/s; 23°C): 30 - 120 mPa.s
- Iodine Colour Number: <= 20
- Non-Volatile Matter (1 h; 125°C; 1 g): 38.5 - 41.5%
- Density (20°C): approx. 0.98 g/cm³
- Flash Point: approx. 63°C
- Appearance: brown, clear liquid
Special Properties:
- High pigment loading without an increase in viscosity.
- Reduction of dispersing time.
- Enhances gloss and leveling.
- Suitable for air drying and stoving solvent-borne paints and particularly for water-dilutable paint systems.
Suggested Uses:
- Prevents the floating of titanium dioxide in conjunction with organic or inorganic colored pigments.
- Enhances gloss and leveling of paint films.
- Allows for increased pigment loading without rises in viscosity.
- Recommended dosage range: 0.1 to 1.5% on total paint. Level on pigments: inorganic pigments (0.5 - 2.5%), organic pigments (1.5 - 5%).
Processing:
- Should be milled together with the pigments to obtain the full effect.
Storage:
- Storage stability packed in original containers at temperatures up to 25°C is at least 730 days.
Distinguishing Features:
- Unlike Additol XL 204, Additol XL 203 is a cationic-active antifloating agent suitable for solvent- and waterborne paint systems. It is not recommended for acid-curing paints.
Compatibility:
- Should not be used in conjunction with certain anionic products to prevent phase separation. Compatibility should be determined by experiments. Can be combined with cationic and non-ionic products.
In summary, ADDITOL® XL 203 serves as an effective antifloating and dispersing agent in various paint systems, contributing to improved pigment dispersion, gloss, and leveling while maintaining stability and compatibility with other components.
