Характеристики

Ключевые свойства и преимущества

High Reactivity: The vinyl group ensures rapid polymerization during UV curing or thermal processes, facilitating efficient production cycles in industrial manufacturing.
Hydroxyl Functionality: Presence of a secondary hydroxyl group enables post-polymerization reactions, allowing for tailored cross-linking with various curing agents.
Enhanced Adhesion: Significantly improves bonding strength on polar substrates, including metals, glass, and certain plastics, essential for high-quality protective coatings.
Weather Resistance: Provides durability and resistance to UV degradation and moisture, ensuring long-lasting performance in outdoor applications and harsh environments.
Excellent Miscibility: Compatible with a wide range of acrylic monomers and solvents, offering flexibility in formulating complex copolymer systems.

Спецификации

Технические особенности

Chemical formula is C6H10O3 with a molecular weight of approximately 130.14 g/mol, ensuring consistent molar calculations for batch formulations.
Typical purity levels exceed 97%, with low levels of acrylic acid and diacrylates to maintain controlled viscosity and polymerization rates.
Physical properties include a boiling point of 77 degrees Celsius at 5 mmHg and a flash point of 99 degrees Celsius.
Viscosity is approximately 5-10 mPa.s at 25 degrees Celsius, allowing for easy handling and efficient mixing in liquid resin systems.
Inhibitor levels, usually MEHQ (Hydroquinone Monomethyl Ether), are strictly regulated to prevent autopolymerization while ensuring shelf-life stability during transport.
