Pentaerythritol tetra(3-mercaptopropionate) is a thiol-functional tetravalent ester used as a crosslinker and stabilizer in polymer, coating, adhesive, and specialty chemical formulations. It contains four mercaptopropionate groups on a pentaerythritol core, providing multiple reactive thiol sites for curing and formulation development.
- Provides four reactive thiol sites for efficient crosslinking.
- Enables thiol-ene and radical curing pathways.
- Improves mechanical strength and thermal stability of cured materials.
- Suitable for polymers, coatings, adhesives, and specialty formulations.
- High purity for consistent performance in research and industrial use.
