Tri(propylene glycol) diacrylate/TPGDA CAS No:42978-66-5 C15H24O6

Core Application Areas

1. Active diluents and crosslinking agents in light-curing/radiation-curing systems‌

2. Significantly reduces the viscosity of UV resin systems and improves application performance;

3. Participates in UV- or electron beam (EB)-initiated polymerization reactions, enhancing curing efficiency and reducing the required radiation dose;

4. After curing, they exhibit both good hardness and flexibility, have low volumetric shrinkage, and demonstrate superior adhesion compared to short-chain analogues (such as DPGDA).

‌Specific End Products‌

1‌. UV Coatings‌: Surface coatings for wood, metal, plastic, and other substrates; particularly suitable for high-end formulations requiring resistance to yellowing and low odor;

2‌. UV Inks‌: Offset, gravure, flexographic, and electronic printing inks, enhancing gloss and adhesion;
