Overview
JD-206 is a polyfunctional aziridine crosslinker for applications requiring high crosslinking efficiency, water, heat and chemical resistance, creep resistance and long-term stability. It reacts with carboxyl groups at room temperature, is suitable for carboxyl-functional systems, is miscible with water and various organic solvents, and can also react under dry conditions.
Typical dosage: 1%–3% based on acrylic or polyurethane binder solids. Cure at room temperature or bake at 60–100 °C. For emulsions and dispersions, a formulation pH of 8–10 is recommended. Crosslinking improves water and chemical resistance, dry and wet rub resistance, anti-blocking properties and coating durability, and enhances adhesion to certain substrates.

Product applications
- Waterborne wood coatings: improves water, abrasion and chemical resistance and adhesion.
- Leather coatings: improves dry/wet rub fastness and chemical resistance.
- Textile printing pastes: improves resistance to stonewashing and enzyme washing and reduces surface blocking.
- Waterborne adhesives: enhances cohesion and helps reduce adhesive residue from protective films on substrates.
- Waterborne inks: improves water and wet-rub resistance and coating printability.
- Waterborne sealants: improves water resistance; enhances cohesion in cement-based systems.
- Vinyl coatings: reduces plasticizer migration and improves stain resistance.
- Waterborne industrial coatings: improves water and solvent resistance.
Safety, Storage, and Packaging
- For industrial use only. Wear suitable personal protective equipment and avoid skin and eye contact. If discomfort occurs, stop exposure, follow the SDS first-aid instructions and seek medical attention promptly. Do not use in acidic media.
