YDN385 Series | Fully Water-Soluble High-Imino Melamine Crosslinkers
The YDN385 Series is a fully water-soluble modified melamine resin platform for aqueous polymer crosslinking and selected specialty waterborne systems. It includes YDN385, YDN385T and YDN385L-60, covering different solids and viscosity windows for application-driven selection.
The YDN385 Series is designed for aqueous polymer crosslinking, textile coatings, nonwoven binders, waterborne industrial coatings, selected microencapsulation systems and other specialty waterborne applications. The series includes YDN385, YDN385T and YDN385L-60, allowing selection across different solids, viscosity and processing requirements.
Start with YDN385, then match the grade to the formulation conditions.
The YDN385 Series is a fully water-soluble modified melamine resin platform mainly used for aqueous polymer crosslinking, textile coatings, waterborne coatings and related functional-material systems.
YDN385 is the standard grade and is suitable for initial evaluation in many compatible aqueous systems. Where viscosity, solids content or processing behavior requires a different window, YDN385T or YDN385L-60 can be evaluated.
Actual crosslinking performance also depends on base-polymer functionality, formulation pH, catalyst system, addition level and cure conditions. Qualification in the complete formulation is recommended.
Formulation value
- Fully water-soluble for compatible aqueous formulations
- High-solids, higher-viscosity and low-viscosity options within one series
- Suitable for evaluation in waterborne coatings, textile coatings and nonwoven binders
- Can be evaluated in selected aqueous microcapsule shell / wall-material systems
Three grades cover different solids and viscosity windows.
The YDN385 Series offers good water solubility across different solids and viscosity ranges, allowing grade selection according to formulation and processing conditions.
| Grade | Solids | pH | Viscosity @30°C | Grade Character |
|---|---|---|---|---|
| YDN385 | ≥78% | 8–10 | 800–1500 mPa·s | Standard high-solids general grade |
| YDN385T | ≥78% | 8–10 | 1500–2000 mPa·s | Higher-viscosity grade |
| YDN385L-60 | ≥58% | 8–10 | 30–100 mPa·s | Low-viscosity, easy-dilution grade |
Technical note: The values above are provided for series selection. Detailed technical specifications should be confirmed against the applicable product documentation and actual supply information.
Match the specification and process window to the actual application.
YDNRESIN normally begins by matching the application to YDN385, YDN385T or YDN385L-60. If an existing grade does not fully cover the required process window, selected technical parameters can be evaluated in relation to polymer structure, formulation medium, cure conditions and target performance.
Parameters that may be evaluated: solids content, viscosity, pH window, water solubility / dilutability, system stability, reaction profile and cure response.
Useful customer inputs
- Base resin / emulsion type and functional groups
- Target solids, viscosity and working-bath pH
- Cure temperature, time and catalyst system
- Final performance and regulatory requirements
Technical development: Application-specific specifications are subject to technical feasibility, laboratory validation and commercial production conditions.
Typical evaluation directions
YDN385 Series or YDN8080 Series?
For aqueous polymer crosslinking, water resistance, chemical resistance and coating-performance requirements, start with the YDN385 Series. For conventional textile finishing focused on easy-care, wrinkle resistance, stiffness/body and wash durability, start with the YDN8080 Series.
Microencapsulation
Microencapsulation should be validated in the laboratory using the actual core material, emulsification system, pH, reaction temperature, shell-formation process, target particle size and storage-stability requirements.
