Tetrahydrofurfuryl acrylate (THFA) with Cas 2399-48-6
What is Tetrahydrofurfuryl acrylate?
Tetrahydrofluorofurfuryl acrylate (THFA) is an important special acrylic ester, with cyclic ether groups in its molecule being more active than linear ether groups. The hydrogen on the alpha carbon of the ether bond also has some activity, and this special structure endows its subsequent products with special properties.THFA has gained prominence in coatings, inks, adhesives, and related fields in recent years. Its unique chemical structure endows it with exceptional properties, making it indispensable in UV curing technology.
Characteristics:
With the molecular formula C8H12O3, THFA combines a tetrahydrofuran (THF) ring and an acrylate group, creating a balance of rigidity and reactivity:
Tetrahydrofuran Ring: The polar ether group enhances adhesion to diverse substrates (e.g., plastics, metals). Its solvation effect on engineering plastics like PC and PET improves coating or adhesive film formation.
Acrylate Double Bond: Provides high reactivity for rapid free radical polymerization, forming stable crosslinked networks.
Low Viscosity & Dilution Capability: With a viscosity of only 10 cP (25°C), THFA outperforms traditional monomers (e.g., TPGDA, TMPTA) in diluting resin systems, ensuring smooth application in inkjet or screen printing processes.
Core Properties Derived from Its Structure:
Superior Adhesion: Strong bonding to plastics (PC, PET, PVC) and metals, minimizing delamination risks.
Low Shrinkage & High Flexibility: Minimal curing shrinkage reduces internal stress, while the cyclic structure enhances toughness to prevent brittleness.
Weather and Chemical Resistance: UV stability, water resistance, and tolerance to acids/alkalis suit harsh environments.
