Product Description
Versatile Crosslinking Monomer NMA48
NMA48 is a key aqueous-phase crosslinking monomer, presented as a water-based solution of N-(Hydroxymethyl)acrylamide. This agent is a transparent liquid, colorless to faint yellow, characterized by a guaranteed N-(Hydroxymethyl)acrylamide content of 42-46%. Functioning as an efficient reactive monomer, NMA48 is extensively adopted in multiple emulsion polymerization applications, proving fundamental in synthesizing self-crosslinking emulsions that substantially augment the end products' mechanical attributes and longevity.

Performance and Applications
- Outstanding crosslinking reactivity: Featuring both hydroxymethyl and acryloyl groups, it integrates into copolymerization chains during free radical polymerization and forms extensive covalent crosslinks through self-reaction or reaction with co-system functional groups (e.g., carboxyl, hydroxyl) under heat treatment. This results in major improvements in polymer water resistance, abrasion resistance, mechanical strength, and thermal stability.
- Textile applications: Instrumental in producing textile finishing agents for durable press, wash-and-wear resins, and coatings. Confers excellent anti-wrinkle properties, dimensional stability, and easy-care performance to textiles while allowing retention of a soft hand feel.
- Adhesives and coatings: Utilized as a crosslinking agent for manufacturing self-crosslinking acrylic emulsions and polyurethane dispersions. Significantly boosts adhesion, resistance to chemicals and staining, and thermal stability in architectural/industrial coatings, composite adhesives, paper treatment chemicals, and leather finishers.
Advantages
- Aqueous solution form ensures user-friendly application, bypassing dissolution difficulties typical of powder products, increasing production efficiency and handling convenience.
- Exhibits high crosslinking efficiency and strong reactivity; modest incorporation significantly raises crosslink density and improves polymer properties.
- Wide-ranging applications across industries, demonstrating excellent copolymerization capability with most vinyl monomers. Comparatively low free formaldehyde level provides favorable environmental performance.
