SE6770 is a solvent-based acrylic polyol resin with a hydroxyl content of 3.0% (based on the theoretical calculation of non-volatile components). It is primarily used to prepare solvent-based two-component polyurethane coatings when mixed with aliphatic isocyanate curing agents.

Key Characteristics

1. Hydroxyl Content: The 3.0% hydroxyl content provides good reactivity, allowing it to effectively cross-link with isocyanate curing agents. This enhances the durability and adhesion of the final coatings.

2. Versatile Applications:

   • PU Topcoat: Suitable for high-performance polyurethane topcoats, delivering excellent gloss and abrasion resistance.
   • Spectacle Frame Paint: Its strong adhesion and chemical resistance make it ideal for coating eyewear frames.
   • Plastic Cover Varnish: Effectively enhances the appearance and protective qualities of plastic surfaces.

3. Solvent-based: As a solvent-based resin, SE6770 offers good flow and film-forming properties, facilitating the creation of uniform coatings.

Suitability

• Polyurethane Coatings: The combination with aliphatic isocyanates results in coatings with outstanding weather resistance and UV stability.
• Environmental Considerations: While solvent-based, it is important to consider environmental and health safety during application by selecting appropriate solvents and handling methods.
