Description
🧪 YDNU-65 High Solid Methylated Urea Formaldehyde Resin
For Fast-Curing Coatings, Water-Based Finishes & Paper Coating Applications
🌟 Product Overview
YDNU-65 is a high-performance methylated urea formaldehyde resin with ≥85% solid content, designed for rapid crosslinking of hydroxyl-containing polymers without the use of acid catalysts. Its fast curing, cost-effective, and solvent-free nature makes it ideal for eco-friendly coatings and paper finishes.
🔧 Key Features
- ✅ Fast Cure (No Catalyst Needed) – 2x faster than conventional UF resins
- ✅ Zero Solvent Content – Compliant with VOC and eco-label regulations
- ✅ High Compatibility – Works with alkyds, acrylics, epoxies, and polyesters
- ✅ Stable & Reliable – 6 months storage without phase separation
- ✅ Low Formaldehyde Release – Safer for handling and end-use
- ✅ Versatile Performance – For baking finishes, clear coats, and paper sizing
📌 Typical Applications
- Fast-drying alkyd baking enamels
- Water-based wood topcoats and clear lacquers
- Paper coating binders
- Industrial metal and furniture finishes
