SINOMER® DDDMA

(Long-Chain Hydrophobic Crosslinking Monomer for Flexible, Fast-Curing Systems)


Chemical Name: 1,12-Dodecanediol Dimethacrylate;1,12-dodecanediyl bismethacrylate

CAS No.: 72829-09-5 

MF:C20H34O4

Molecular Structure:


Overview:

SINOMER® DDDMA (1,12-Dodecanediol Dimethacrylate) is a difunctional methacrylic monomer featuring a long C12 hydrophobic spacer chain between two reactive methacrylate end groups. This unique molecular structure provides exceptional flexibility, low 粘度, and enhanced molecular mobility. The long hydrophobic backbone effectively reduces curing shrinkage while imparting excellent weatherability and surface characteristics to the cured polymer matrix.

SINOMER® DDDMA exhibits fast curing response and non-yellowing properties, making it an ideal crosslinking monomer for applications requiring a balance of flexibility, toughness, and durability. It is widely adopted in biomaterials, dental composites, coatings, sealants, and specialty adhesives.
