Product Application of Pentaerythritol Triacrylate CAS#3524-68-3
Thanks to its plentiful acrylate functional groups, the monomer is capable of fast-speed solidification when exposed to ultraviolet rays or electron-beam radiation.
The substance enjoys broad-ranging utilization in several manufacturing fields. It serves as core raw-material for high-end radiation-hardened surface coatings. Besides, it is incorporated into ultraviolet-curable bonding agents and printing ink formulas. Micro-electronic components and printing-plate processing also adopt this acrylate monomer for the fabrication of photoresist raw materials.
