Description

Tris[2-(3-Mercaptopropionyloxy)Ethyl] Isocyanurate is a multifunctional thiol compound, serving as a crucial crosslinking agent and chain transfer agent in advanced polymer synthesis. Its molecular structure, featuring three reactive mercaptan groups, enables precise control over polymer network formation and molecular weight, which is essential for achieving specific material properties. This product is particularly valuable for manufacturers in the optical lens, adhesive, sealant, and specialty coating industries who require materials with enhanced clarity, refractive index, and durability.

Application

• Optical Resin & Lens Manufacturing: A key monomer for high-refractive-index optical plastics used in eyeglasses, camera lenses, and LED encapsulants.
• UV-Curable Coatings & Inks: Acts as a reactive diluent and crosslinker to improve adhesion, flexibility, and scratch resistance.
• Epoxy Resin Modification: Used as a curing agent or toughening additive to enhance the impact resistance and thermal stability of epoxy systems.
• Polyurethane Elastomers: Functions as a chain extender or crosslinker to fine-tune the hardness, elasticity, and chemical resistance of PU products.
• Adhesives and Sealants: Imparts improved weatherability and bond strength, especially in formulations requiring low yellowing and high transparency.
• Polymer Synthesis (RAFT Agent): Serves as a chain transfer agent in Reversible Addition-Fragmentation Chain Transfer (RAFT) polymerization for producing polymers with controlled architecture.
