Description of 1,3,4,6-tetrakis(hydroxymethyl)-3a,6a-dihydroimidazo[4,5-d]imidazole-2,5-dione
1,3,4,6-Tetrakis(hydroxymethyl)-3a,6a-dihydroimidazo[4,5-d]imidazole-2,5-dione (CAS: 5395-50-6), commonly known as Tetramethylol acetylenediurea or Tetrahydroxymethyl glycoluril, is a multifunctional hydroxymethyl compound. This compound serves as an effective crosslinking agent and formaldehyde donor in textile finishing resins, coatings, and adhesives.
Application of 1,3,4,6-tetrakis(hydroxymethyl)-3a,6a-dihydroimidazo[4,5-d]imidazole-2,5-dione
Textile Wrinkle-Resistant Finishing. Used as a crosslinking agent in durable-press and wrinkle-resistant treatments for cotton and cotton-blend fabrics, providing excellent crease recovery and durability.
Formaldehyde-Based Resin Crosslinker. Serves as a formaldehyde donor in urea-formaldehyde and melamine-formaldehyde resins, enhancing crosslinking efficiency, mechanical strength, and water resistance.
Coatings and Adhesives. Incorporated into industrial coatings, laminates, and adhesives to improve film hardness, adhesion, and chemical resistance.
Paper and Nonwoven Treatments. Applied in wet-strength paper, tissue, and nonwoven fabrics to increase tensile strength and dimensional stability.
Wood and Particle Board Resins. Functions as a binder or modifier in particleboard, plywood, and wood composite adhesives for better bonding and moisture resistance.
Storage of 1,3,4,6-tetrakis(hydroxymethyl)-3a,6a-dihydroimidazo[4,5-d]imidazole-2,5-dione
It should be kept in a tightly sealed original container in a cool, dry, well-ventilated area away from direct sunlight, heat, and moisture. Recommended storage temperature: 5–25°C (room temperature). Keep away from strong acids, bases, oxidizing agents, and sources of ignition. The product is moisture-sensitive and may release formaldehyde or degrade upon prolonged exposure to humidity. Avoid contact with water or aqueous solutions.
