Description

2-Hydroxypropyl 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 specialty polymers with tailored properties, such as enhanced adhesion, crosslinking capability, and hydrophilicity. It is essential for manufacturers in the coatings, adhesives, and advanced materials sectors seeking to develop high-performance, customizable resin systems.

Application

• UV-Curable Coatings and Inks: As a reactive diluent and crosslinker to formulate fast-curing, low-VOC, and high-gloss finishes for wood, plastic, and metal substrates.
• Pressure-Sensitive Adhesives (PSAs): To introduce polar hydroxyl groups into acrylic polymer backbones, improving adhesion to various surfaces and allowing for crosslinking to enhance cohesive strength.
• Hydrogel and Contact Lens Materials: As a co-monomer to impart hydrophilicity, flexibility, and oxygen permeability in biomedical and personal care polymer networks.
• Fiber Optic Coatings: In radiation-curable coatings that provide protective, flexible layers with excellent adhesion to glass fibers.
• Automotive and Industrial Coatings: For enhancing the chemical resistance, durability, and adhesion properties of acrylic polyol resins used in topcoat formulations.
• Textile and Leather Finishes: As a component in polymer emulsions and resins that provide durable, flexible, and water-resistant finishes.

Quality Control

Our 2-Hydroxypropyl Acrylate is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, purity, and impurity profile determination via GC and HPLC. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat, sparks, and open flame. Due to the presence of inhibitors, monitor storage time and temperature to maintain product stability.
