Description

n-Methylolacrylamide is a versatile bifunctional monomer containing both a polymerizable vinyl group and a reactive N-methylol group. This unique structure makes it a critical cross-linking agent for enhancing the performance of polymers, particularly in applications requiring improved durability, water resistance, and dimensional stability. It is essential for manufacturers in the coatings, adhesives, textile finishing, and paper industries seeking to upgrade product performance.

Application

• Cross-linking Agent for Acrylic Polymers: Imparts thermosetting properties to coatings, adhesives, and binders, improving their hardness, chemical resistance, and weatherability.
• Textile Finishing: Used in the production of durable press (DP) and wash-and-wear fabrics, providing crease resistance and shape retention to cellulose fibers.
• Paper Coating & Sizing: Enhances the wet strength, printability, and surface properties of paper and paperboard.
• Photoresist & Photopolymer Formulations: Serves as a reactive component in UV-curable inks, photoresists, and printing plates.
• Soil Stabilization & Grouting Agents: Acts as a co-monomer in polymers used for soil consolidation and waterproofing in construction.
• Flocculants & Water Treatment Polymers: Incorporated into polyacrylamide-based flocculants to modify charge density and improve performance.

Quality Control

Our n-Methylolacrylamide is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, appearance, and stability. A Certificate of Analysis (COA) detailing assay, moisture content, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to polymerization or degradation.
