What is Trimethylolpropane diallyl ether?
Trimethylolpropane diallyl ether (CAS 682-09-7) is a reactive monomer combining a free hydroxyl group with two allyl ether functionalities in a single molecule.
Where is Trimethylolpropane diallyl ether used?
- Coatings: reactive diluent and crosslinker in UV- and peroxide-cured systems, contributing flexibility to the cured film without sacrificing network density
- Adhesives and sealants: tunes crosslink density and improves elongation in elastomeric systems
- Two-component coatings: the pendant hydroxyl group enables co-reaction with isocyanates or melamine resins
- Ink binders for printing and packaging
- Polymer synthesis: introduces controlled branching or acts as a functional comonomer where both allyl and hydroxyl reactivity need to be addressed
- Its dual reactivity allows it to participate in both crosslinking networks and hydroxyl-reactive curing systems.
Commercial specifications
- Drum and IBC packaging are typical for commercial supply volumes
