High hardness & fast cure speed – rapidly develops surface hardness
Low shrinkage & low deformation – reduced volume contraction during cure, excellent dimensional stability
Reduced skin irritation – milder than many conventional acrylates (e.g., HDDA, TMPTA)
Bio-based content – derived from renewable resources, supports green formulation goals
Excellent adhesion – good bonding to plastics, metals, and other substrates
Halogen-free – compliant with EU RoHS directive
Good compatibility – miscible with acrylic oligomers and other monomers
UV curable plastic coatings
UV printing inks (offset, screen, flexo)
UV adhesives
Photosensitive resins for electronics
Electronic appliances, automotive parts, architectural decoration
SINOMER® ISDA provides a unique balance of bio‑sourced content, fast cure, low irritation, and low shrinkage – making it an attractive choice for high‑performance, environmentally conscious UV formulations.
