Description

Tris(Hydroxymethyl)Urea is a versatile organic compound derived from urea and formaldehyde, serving as a key intermediate in various chemical syntheses. Its primary value lies in its ability to act as a reactive source of hydroxymethyl groups, making it essential for creating cross-linked polymers and resins. This product is particularly needed by manufacturers in the adhesives, textile finishing, and specialty chemical industries, where it contributes to product durability and performance.

Application

• Resin and Polymer Synthesis: A crucial monomer for producing amino resins, urea-formaldehyde resins, and other thermosetting polymers used in wood adhesives and molding compounds.
• Textile Industry: Employed as a durable press finishing agent and cross-linking agent for cellulose fibers to impart wrinkle resistance and dimensional stability to fabrics.
• Paper Manufacturing: Used as a wet-strength additive and coating agent to improve the mechanical properties and printability of paper products.
• Leather Tanning: Acts as a tanning auxiliary and filling agent to enhance the softness, fullness, and dye uptake of leather.
• Adhesive Formulations: Serves as a key component in the formulation of high-performance industrial and woodworking adhesives.
• Chemical Intermediate: Utilized in organic synthesis for the preparation of more complex molecules in pharmaceutical and agrochemical research.

Quality Control

Our Tris(Hydroxymethyl)Urea is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and appearance are available upon request to support your quality assurance and regulatory needs.

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 to minimize exposure to atmospheric moisture, which can affect product quality and handling properties.
