Product Name:Pentaerythritol tetraacrylate
English Name:Pentaerythritol tetraacrylate
CAS No.:4986-89-4
Aliases:PETA, Pentaerythritol tetrakis(acrylate), Tetramethylolmethane tetraacrylate
Molecular Formula:C17H20O8
Physical Properties:It is a colorless to light yellow transparent viscous liquid with a slight ester odor and a molecular weight of 352.34. Density at 25°C is about 1.10–1.20 g/cm³, viscosity at 25°C is about 500–1000 mPa·s, and refractive index is about 1.48. It is soluble in acetone, toluene, ethyl acetate and other organic solvents, but insoluble in water. It has a high boiling point (above 350°C) and readily polymerizes upon heating; therefore, it should be stored sealed in a cool, dark place and usually contains a polymerization inhibitor.
Uses:It is used as a tetrafunctional crosslinking monomer in UV/EB curable coatings, inks, adhesives and photosensitive resins, significantly improving curing speed, crosslinking density, hardness, scratch resistance and chemical resistance of the cured film. It is also used in the preparation of high-refractive-index optical materials and composite matrices.
Technical Specifications:
Appearance: colorless to light yellow transparent viscous liquid
Purity: ≥95%
Viscosity (25°C): 500–1000 mPa·s
Acid value: ≤0.5 mg KOH/g
Moisture: ≤0.1%
