Характеристики

Ключевые свойства и преимущества

Dual-functional monomer combining a reactive acrylic vinyl group and a primary hydroxyl group for versatile chemical modifications.
Exceptional adhesion promotion on various substrates, including metals, glass, and plastics, due to the high polarity of the hydroxyl group.
Highly hydrophilic nature, making it ideal for the formulation of water-borne systems and specialty hydrogel materials.
Rapid curing response in radiation-curable (UV/EB) formulations, improving the overall crosslinking density and chemical resistance of films.
Facilitates post-polymerization reactions, allowing the secondary crosslinking with polyisocyanates to create high-durability polyurethane-modified acrylic systems.

Спецификации

Технические особенности

Chemical Formula: C5H8O3 with a molecular weight of approximately 116.12 g/mol, appearing as a clear, low-viscosity liquid.
Specific gravity of 1.106 at 20 degrees Celsius and a refractive index of approximately 1.450 for optical clarity.
Boiling point of approximately 197 degrees Celsius at atmospheric pressure, though it typically undergoes polymerization before reaching this temperature.
Flash point of 101 degrees Celsius (closed cup), requiring storage in cool, ventilated areas away from heat sources.
Purity levels typically exceed 97 percent, with moisture content controlled below 0.2 percent and MEHQ inhibitor levels at 200-400 ppm.

Практическое применение в отраслях

Области применения

Automotive coatings and topcoats where high gloss, weather resistance, and scratch resistance are critical performance requirements.
Synthesis of thermosetting acrylic resins used in industrial finishes, providing sites for crosslinking with melamine or isocyanate resins.
Formulating UV-curable inks and varnishes to enhance surface hardness, chemical durability, and substrate adhesion properties.
Production of specialty contact lenses and medical hydrogels due to its biocompatibility and high water-swelling capacity once polymerized.
Pressure-sensitive adhesives and textile finishes where increased cohesive strength and bonding performance are necessary for demanding environments.
