Polymer Crosslinking
Acts as a crosslinking agent in the production of polymers, improving the mechanical strength, rigidity, and solvent resistance of the final material. It is particularly useful in acrylate-based polymer systems.
Reactive Diluent
Functions as a reactive diluent in radiation-curable formulations, reducing viscosity while becoming incorporated into the polymer network during curing. This leads to improved processing and performance characteristics.
Adhesives and Coatings
Incorporated into formulations for adhesives and coatings to enhance durability, adhesion, and resistance to environmental factors. Its crosslinking ability contributes to tougher, more resilient films.
Dental Materials
Used in the development of dental composites and adhesives, where its crosslinking properties contribute to the strength, wear resistance, and dimensional stability required for restorative applications.
