Hydroxypropyl Methacrylate (HPMA) — CAS 27813-02-1
Hydroxypropyl Methacrylate (HPMA) is a functional methacrylate monomer widely used in coatings, adhesives, specialty polymers and resin modification.
It provides hydroxyl functionality for crosslinking and improves final polymer performance. Commercial HPMA is an isomeric mixture dominated by the secondary hydroxyl isomer (~75–80%), offering balanced hardness and extended pot life.
