Chemical & Physical Properties:
- Composition: High molecular weight modified silicone
- Appearance: Viscous liquid
- Non-volatile content: 78~82%
- Solvent: Water
- Specific gravity: Approximately 0.98
Applications:
- Suitable for use in various applications including:
- Waterborne inks, coatings, and leather refinishing
- Solvent-borne inks containing polar solvents
Key Properties:
- Imparts slip, mar-resistance, and anti-blocking characteristics
- Provides excellent hand feel and slip performance
- Enhances water resistance and improves leveling & wetting
Incorporation:
- Recommended to be diluted with water or compatible solvent before use
- Best incorporated at the grinding stage to ensure proper dispersion and performance
- High shear mixing is required if incorporated at the post-addition stage
Levels of Use:
- Typically used at levels ranging from 0.05% to 3.0% based on the total formulation weight
- Conduct a ladder study to determine the optimum dosage for specific applications
Health and Safety:
- Product should be tightly closed to prevent crust formation due to surface drying
- Avoid eye and skin contact
- Consult the Safety Data Sheet (SDS) for detailed information on safe handling and storage
