Description

2-Hydroxyethyl Acrylate is a versatile bifunctional monomer containing both a polymerizable acrylate group and a reactive hydroxyl group. This dual functionality makes it a critical building block for synthesizing polymers with tailored properties, such as enhanced adhesion, crosslinking capability, and hydrophilicity. It is essential for manufacturers in the coatings, adhesives, textile, and personal care industries seeking to develop high-performance, customizable materials.

Application

• UV-Curable Coatings & Inks: A key component in formulations for wood, plastic, and metal coatings, providing fast curing, high gloss, and chemical resistance.
• Acrylic Resins & Polymers: Used to produce hydroxy-functional acrylic copolymers for automotive, industrial, and architectural coatings.
• Adhesives & Sealants: Imparts improved adhesion to various substrates and enables crosslinking in pressure-sensitive and structural adhesives.
• Reactive Diluents: Functions as a low-viscosity, reactive monomer to modify the rheology of oligomer systems without compromising performance.
• Textile & Leather Finishes: Employed in binders and finishing agents to create durable, flexible, and water-resistant fabrics and leathers.
• Hydrogel Production: Serves as a monomer for synthesizing hydrophilic polymers used in contact lenses, wound dressings, and agricultural products.
