Product Name:1,4-Butanediol diacrylate
English Name:1,4-Butanediol diacrylate
CAS No.:1070-70-8
Aliases:BDDA, Tetramethylene diacrylate, 1,4-Bis(acryloyloxy)butane
Molecular Formula:C10H14O4
Physical Properties:Clear liquid at room temperature with an ester characteristic odor. Molecular weight 198.22, density approximately 1.051 g/cm³ at 25°C, boiling point approximately 276°C at normal pressure, flash point approximately 143°C (closed cup). Slightly soluble in water; soluble in common organic solvents such as alcohols, ketones, esters, and aromatic hydrocarbons. Irritating to skin and eyes; direct contact should be avoided.
Uses:As a difunctional acrylate monomer, it is mainly used as a reactive diluent in UV-curable coatings, inks, and adhesives, effectively increasing crosslinking density and film hardness. It is also used in the synthesis of photosensitive resins, optical materials, and fiber modification, imparting good weather resistance and mechanical strength.
Technical Specifications:
Appearance: clear liquid at room temperature
Ester content: ≥98.0%
Acid value: ≤0.5 mg KOH/g
Water content: ≤0.1%
Inhibitor content: 200-400 ppm MEHQ
