Description

Urea, N,n-Bis(Hydroxymethyl)- (9Ci) is a versatile chemical intermediate belonging to the class of N-methylol compounds. This compound matters for its ability to act as a reactive cross-linking agent and a source of formaldehyde, making it crucial for modifying the properties of polymers and resins. Industries such as textile manufacturing, paper production, and specialty polymer synthesis need this chemical for applications ranging from durable press finishes to wet-strength additives.

Application

• As a key intermediate in the production of amino resins for wood adhesives and coatings.
• As a durable press (DP) or anti-crease finishing agent for cellulose-based textiles like cotton.
• In the manufacture of wet-strength resins for paper and paperboard products.
• As a cross-linking agent in the synthesis of specialty polymers and thermosetting plastics.
• In the formulation of leather tanning auxiliaries and finishing chemicals.
• As a component in slow-release fertilizer systems and agricultural chemical formulations.
• For research and development in organic synthesis as a building block for heterocyclic compounds.
