Products Description
BPMA is a single-functional acrylate with a high refractive index and excellent waterproof and scratch-resistant properties.
UV/LED-UV has excellent curing performance. The cured film is highly transparent, with low yellowing, good heat resistance and weather resistance, high hardness and good wear resistance. It has good compatibility with various acrylic oligomers. It is a special functional monomer specifically used for high-end UV curing formulations in the fields of optics and microelectronics.

FAQ
Q: What is its function in OCA?
A: Raise refractive index to match optical interface and reduce light loss; lower curing shrinkage and improve thermal stability.
Q: How to store BPMA?
A: Keep sealed, away from light, store at low temperature. Stabilized with MEHQ to prevent thermal polymerization.
Q: Is cured film easy to turn yellow?
A: Biphenyl structure is more stable than many aromatic acrylates, delivering better long-term anti-yellowing performance.
Q: Why use BPMA for photoresist?
A: Rigid biphenyl skeleton brings high Tg, high resolution and good etch resistance for advanced photoresist.
