Application
Trimethylolpropane Tris(3-mercaptopropionate) is an industrial organic intermediate that can be used as a linker, polymerization modifier and photocuring agent. It is widely used in photocurable coatings, photosensitive materials, printed circuit boards or other functional materials.
This product is used in photocurable coating systems to improve the adhesion, hardness, toughness and other properties of the coating, and improve the curing performance and surface properties of the coating. At the same time, this product can be used as a photocurable comonomer or photocuring agent for polymers such as vinyl, (meth) acrylic acid, and polyiso(thio)cyanate to prepare optically transparent materials, improve the transparency and refractive index of the resin, and improve the impact resistance, dyeability and processability of the resin.
