Hydroxypropyl Acrylate (HPA) is also a very useful feedstock for chemical syntheses because it readily undergoes addition reactions with a wide variety of organic and inorganic compounds.

Features & Benefits

It can be used to impart the following properties to polymers:

  • Chemical resistance
  • Crosslinking
  • Adhesion
  • Scratch resistance
  • Weatherability
  • Rheology modifier
  • Low VOC

Storage & Handling:

In order to prevent polymerization, Hydroxypropyl Acrylate (HPA) must always be stored under air, and never under inert gases. The presence of oxygen is required for the stabilizer to function effectively. It has to contain a stabilizer and the storage temperature must not exceed 35 °C. Under these conditions, the storage stability of one year can be expected upon delivery. In order to minimize the likelihood of over storage, the storage procedure should strictly follow the “first-in-first-out” principle. For extended storage periods over 4 weeks it is advisable to replenish the dissolved oxygen content.
