Performance and Applications
- Superior crosslinking properties: Bifunctional hydroxymethyl and acryloyl groups participate in copolymerization during free radical polymerization and establish stable covalent crosslinked networks upon heating, improving polymer properties like water resistance, mechanical strength, and thermal stability.
- High-end textile finishing: Eco-friendly crosslinking monomer for producing low- or formaldehyde-free finishing agents. Enhances fabric wrinkle resistance, dimensional stability, and durable press performance while preserving soft hand feel and breathability.
- Eco-friendly adhesives and coatings: Used for synthesizing self-crosslinking acrylic emulsions and waterborne polyurethane dispersions with low formaldehyde emission. Improves adhesion, water resistance, chemical resistance, and thermal stability.
Key Advantages
- Exceptionally low free formaldehyde content (<0.2%), superb environmental profile, complying with stringent international regulations
- Aqueous form ensures user-friendly handling, eliminates dissolving difficulties, enhances production efficiency and operational convenience
- High crosslinking efficiency, strong reactivity, and good copolymerizability with various vinyl monomers
