Product Description

Product Name	Tetrahydrofurfuryl Acrylate (THFA) (Monofunctional Flexible Monomer)
CAS NO.	2399-48-6
Formula & Weight	C8H12O3 (MW: 156.18)
Chemical Structure
Technical Specifications	Appearance: Clear colorless liquid Assay (GC): ≥ 98.0% (Typ. 99.0%) Color (APHA): ≤ 30 Acid Value: ≤ 0.5 mg KOH/g Water Content: ≤ 0.1% Tg (Glass Transition): -15°C (Flexible) Viscosity (25°C): 2 - 4 mPa.s (Low Viscosity) Inhibitor (MEHQ): 100 - 200 ppm
Why Use THFA?	The go-to monomer for difficult adhesion & flexibility: Excellent Adhesion: The cyclic ether group promotes strong bonding to difficult substrates like metal, glass, and PET plastics. Flexibility Modifier: With a low Tg (-15°C), it acts as an internal plasticizer, improving the impact resistance and flexibility of coatings. High Solvency: Exceptional ability to dissolve and dilute high-viscosity oligomers and resins, reducing the need for non-reactive solvents. Applications: UV Inkjet Inks, Flexible Coatings, 3D Printing Resins, and Metal Varnishes.
Packaging & Handling	Packaging: 200kg Plastic Drum / 1000kg IBC Tank. Storage: Store in a cool, dry place. Avoid heat and direct sunlight to prevent premature polymerization.
