🔬 Why PO2-NPGDA Excels in These Applications

PO2-NPGDA is a propoxylated modification of neopentyl glycol diacrylate (NPGDA), whose unique structure delivers key characteristics:

Superior Comprehensive Performance:
While retaining NPGDA’s high reactivity, hardness, and scratch resistance, the introduction of flexible propoxy chains results in cured films that are not only rigid but also more flexible. This enhances adhesion to substrates like plastics and prevents brittle cracking.

Outstanding Processability:
Its low viscosity effectively dilutes and adjusts resin system viscosity, improving application properties. Simultaneously, its low skin irritation enhances production safety.

Critical Low Shrinkage:
It exhibits minimal volume shrinkage during curing (typically <5%), which is crucial for dimensional accuracy in 3D printing, coating adhesion, and internal stress control in electronic encapsulation.
