Description
DPOLYTHIOL 309 is a high-performance multifunctional thiol compound designed for advanced polymer curing and modification systems. It delivers fast reaction speed, excellent crosslinking efficiency, and reliable mechanical enhancement, making it ideal for high-demand coating, adhesive, and resin applications.escription
The key feature of POLYTHIOL 309 lies in its high thiol functionality, which allows it to participate efficiently in click-type reactions and step-growth polymerization. Compared with low-molecular-weight mercaptans, its polymeric structure provides better handling safety, lower odor, and improved formulation stability.
Main features include
● High mercapto group content for efficient crosslinking
● Controlled molecular weight for predictable reactivity
● Low volatility and reduced odor compared to small-molecule thiols
● Good compatibility with epoxy, acrylate, and vinyl systems
These characteristics make POLYTHIOL 309 particularly suitable for industrial formulations requiring precision and reliability.
