Products Description
The molecule is equipped with three types of active groups:
1. Acrylic double bond: UV light-cured free radical crosslinking;
2. Secondary hydroxyl group: Can undergo secondary crosslinking with isocyanates and acid anhydrides, enhancing adhesion;
3. Phenolic oxygen-containing aromatic ring structure: High refractive index, low dielectric loss, strong temperature resistance, improving resin rigidity and weather resistance.
2-Hydroxy-3-Phenoxypropyl Acrylate (HPPA, CAS 16969-10-1) is a multifunctional acrylate monomer with acrylate double bond, reactive hydroxyl group and phenoxy ring, widely applied in 5G high-frequency copper-clad laminates, UV curable coatings and low-shrinkage 3D printing resins with low dielectric loss and high refractive index.

FAQ
FAQ
Q: Can I visit your factory?
A: Sure! Welcome anytime.
Q: How about the payment items?
A: L/C, D/P, T/T.
Q: Can you accept the inspection from a third party?
A: Yes. We have enough experience to cooperate with the inspection project.
Q: How long is the delivery time?
A: Usually, the shipment can be delivered within 10-15 days after the order is confirmed.
Q: Could COA and MSDS documents be provided for each batch?
A: For each batch, we can provide the complete set of COA and MSDS documents.
Q: Will there be any resin yellowing problem under the high-temperature and high-pressure bonding process?
A: Under normal copper-clad laminate high-temperature lamination conditions, it shows a slight yellowing. Overall, its temperature resistance and anti-yellowing properties are much better than those of ordinary hydroxy acrylate monomers.
Q: Could hydroxyl groups enhance the adhesion of the paint film to the plastic substrate?
A: Sure. The hydroxyl groups can anchor to the polar groups on the plastic surface, significantly enhancing the adhesion of the paint film.
Q: To what extent can the addition achieve a reduction in the curing shrinkage rate of the photosensitive resin?
A: It can effectively reduce the solidification shrinkage rate by approximately 30% to 45%, significantly reducing the warping deformation of the printed piece.
Q: Will it enhance the toughness and bending resistance of the printed product?
A: Sure. The phenolic flexible structure effectively enhances toughness and bending resistance, and is less prone to cracking.
Q: Could the modification with epoxy improve the moisture resistance and heat resistance properties?
A: Sure. The rigid structure of the benzene ring combined with the increased cross-linking density of the hydroxyl groups can significantly enhance the moisture resistance and boiling water resistance of the modified epoxy.
