1. UV-Curing Coatings/Inks
As a multifunctional thiol monomer, it participates in photocuring through a “thiol-ene” click chemistry reaction, improving the adhesion, hardness, weather resistance, and curing speed of coatings.

2. Adhesives
As a crosslinking agent, it enhances the interfacial bonding force between organic and inorganic materials, thereby improving bonding strength and water resistance.

3. Polymer Modification
As a modifier or chain extender, it is used in the synthesis of special polymers such as sulfur-containing epoxy resins, improving the heat resistance, chemical resistance, and mechanical properties of the final product.

4. Electronic Packaging Materials
Used in photoresist or sealant formulations, it helps improve the dielectric properties and mechanical strength of the materials.

🧪 Detailed Application Scenarios
The wide application of BDDMP is mainly due to the two highly reactive thiol groups (-SH) at its molecular ends, enabling it to play a key role in multiple fields:

Role in UV-curing systems:
Under ultraviolet (UV) irradiation, the thiol groups of BDDMP can undergo efficient “thiol-ene” click chemistry reactions with carbon-carbon double bonds (such as acrylates) in the system. This reaction accelerates the curing speed, and the resulting thioether bonds make the coating denser, thus improving adhesion, hardness, and scratch resistance. Therefore, it is an important raw material for high-performance UV coatings and inks.

As a high-performance crosslinking agent:
In adhesives or composite materials, the thiol groups of BDDMP can react with various functional groups (such as epoxy groups, isocyanate groups), forming a strong chemical crosslinking network between molecules. This significantly improves the water resistance, heat resistance, and dimensional stability of the material.

Synthesis of special polymers:
As a reactive intermediate, BDDMP can be used to construct polymer backbones. For example, reacting with glycidyl methacrylate (GMA), it can synthesize sulfur-containing epoxy resins with thioether bonds in the main chain. These materials usually have superior heat resistance and chemical resistance, suitable for fields with demanding material requirements.
