CAS 220140-29-4 : Modified Asymmetric Glycoluril

Chinese name: Four ( Methoxymethyl )-3a- Methyl -6a- Propyl Glycine

English name: Imidazo[4,5-d]imidazole-2,5(1H,3H)-dione, tetrahydro-1,3,4,6-tetrakis(methoxymethyl)-3a-methyl-6a-propyl-

Molecular formula: C ₁₈ H ₃₄ N ₄ O ₆

Appearance: Liquid or low-melting solid (depending on purity)

Innovations and Applications: This compound represents a significant advancement over the traditional guanidine scaffold.

Structural asymmetry: by introducing a substituent at the bridgehead position of the guanidine scaffold ( 3a and 6a position) introduces asymmetric alkyl chains (methyl and propyl), thereby breaking the molecular symmetry. This “ Entropy increase ” The design significantly reduces the molecule’s crystallinity, enabling it to exist in a liquid state or to be highly soluble in common organic solvents.

Formulation compatibility: When formulating high-solids coatings ( High Solids Coatings ) At this point, the product exhibits improved miscibility with polyesters and acrylic resins, resulting in a more uniform coating and reduced orange-peel effect.

Crosslinking performance: It retains four methoxymethyl groups ( -CH₂OCH₃ ), under acid catalysis, it can still efficiently undergo transesterification with the hydroxyl groups in the resin, forming a dense crosslinked network that delivers outstanding hardness and chemical resistance.  。   

We have a professional export team and our brushes are exported to European and American countries. We can do OEM and ODM services. We have a brush design team that develops and designs new brushes every year.
