Propoxylated neopentyl glycol diacrylate is a low-viscosity, difunctional acrylate monomer widely used in UV curing and EB curing systems.. It polymerises quickly via free-radical reaction to produce a cross-linked polymer.
Because of its low viscosity and high reactivity, it’s commonly blended with:
Photoinitiator
- Photoinitiator 819
- TPO
- Benzophenone
Amine synergists
These additives work in concert to deliver fast cure, surface dry and conversion rates.
Moreover, this monomer has superior flexibility and adhesion, and is a high-performing UV-curable formulation.

Q1: What is the function of this product in UV-curable products?
A: It’s a reactive monomer which, after being initiated by the photoinitiator, polymerises via a cross-linked network.
Q2: With which products should the monomer be combined?
A: It is commonly used with the following products:
- Photoinitiators (e.g., 819, TPO, Benzophenone)
- Amine Synergists (e.g., EDB)
- Light Stabilizer
Q3: Do I need a photoinitiator?
A: Yes. If you don’t use a photoinitiator, the monomers will not polymerise under UV exposure.
Q4: What are the main benefits of using this monomer?
A: It has the following properties:
- Low viscosity
- Good flexibility
- Fast curing speed
Q5: How can polymerization during storage be avoided?
A: Inhibitors are usually added to Polymerization Inhibitor from occurring in storage.
