Description

Tetramethylol Acetylenediurea is a highly functionalized, cross-linking chemical agent derived from acetylenediurea. This compound matters for its ability to form durable, water-resistant bonds with hydroxyl-containing polymers, making it a key component in high-performance resin systems. Industries such as textile finishing, paper manufacturing, and specialty adhesives rely on its unique reactivity to enhance product durability and performance under demanding conditions.

Application

• As a durable press agent and cross-linker in textile finishing for wrinkle-resistant fabrics.
• As a wet-strength resin in paper and paperboard production.
• As a key component in the formulation of high-performance, water-resistant wood adhesives and laminates.
• As a cross-linking monomer in the synthesis of specialty polymers and coatings.
• In the production of flame-retardant and soil-release finishes for technical textiles.
• As a reactant in the manufacture of melamine-urea-formaldehyde (MUF) resin modifiers.

Quality Control

Our Tetramethylol Acetylenediurea is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, reactivity, and physical properties. A Certificate of Analysis (COA) detailing assay, moisture content, and other critical parameters is provided with every shipment to guarantee consistency and traceability for your production processes.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product performance.
