Product Description: WynCoat* SE-4251

WynCoat* SE-4251 is a specialized additive designed to enhance the performance of both water-based and solvent-based coating systems. It is an 80% active dispersion of a very high molecular weight polydimethylsiloxane (PDMS) gum, renowned for its beneficial properties in various industrial applications.

Key Features and Benefits:

1. High Active Content:

   • Solid Content: 80%
   • This high concentration ensures effectiveness even at low addition levels.

2. Viscosity:

   • At 25ºC: ≥20000 cp
   • The high viscosity indicates a substantial presence of the active ingredient, contributing to its performance in coatings.

3. Appearance:

   • White, Viscous Liquid: Easy to incorporate into formulations without altering the appearance significantly.

4. Additive Performance:

   • Slip: Reduces the coefficient of friction, making surfaces feel smoother.
   • Mar Resistance: Protects surfaces from scratches and scuffs.
   • Gloss Enhancement: Improves the shine and aesthetic appeal of coated surfaces.
   • Anti-blocking: Prevents coated surfaces from sticking together.
   • Release Effects: Facilitates the release of molded parts or layers in various applications.

5. Manufacturing:

   • Tin-based catalysts are not used, making it more environmentally friendly and safer for specific applications.

Applications and Uses:

WynCoat* SE-4251 is versatile and suitable for a range of applications in paints, inks, and coatings. It is particularly effective in solvent-based coatings, including:

• Leather Top Coats: Enhances the finish and durability of leather products.
• Paints and Inks: Improves handling and performance characteristics.
• Coatings Formulations: Used to impart desirable properties such as slip, mar resistance, and gloss.

Usage Guidelines:

• Application Range: 0.05-3.00% weight percent based on the total formulation.
• Incorporation: Can be added directly or pre-diluted with water or the solvent used in the coating system.
• Effectiveness: Particularly notable in solvent-based systems.

Packaging and Storage:

• Available Sizes: 20 kg pail and 200 kg drums.
• Storage Conditions: Store between 10°C and 40°C in the original unopened container.
• Shelf Life: 24 months from the date of manufacture when stored properly.

Limitations:

• Not for Medical or Pharmaceutical Uses: The product is neither tested nor represented as suitable for medical or pharmaceutical applications.

Product Safety:

• Handling: Refer to the product’s Safety Data Sheet (SDS) for detailed information on safe handling and usage practices.
• Safety Measures: Ensure proper protective equipment and handling procedures are followed to avoid any health and safety risks.

Summary:

WynCoat* SE-4251 is an advanced additive designed to enhance the properties of coating systems, providing benefits such as slip, mar resistance, gloss, anti-blocking, and release effects. Its high active content and viscosity make it highly effective in a range of applications, particularly in solvent-based coatings for leather and other surfaces. Proper storage and handling ensure a long shelf life and maintain the product's efficacy over time.
