Description

Poly(Hydroxypropyl Acrylate) is a functional acrylic polymer derivative, also known as Poly(2-Hydroxypropyl acrylate). This versatile polymer is valued for its reactive hydroxyl groups and acrylic backbone, making it a key intermediate and performance additive. It is primarily used in the formulation of advanced coatings, adhesives, and specialty polymers where enhanced adhesion, crosslinking capability, and hydrophilicity are required. Industrial buyers in sectors such as paints & coatings, pressure-sensitive adhesives, and biomedical materials rely on its consistent quality for product development and manufacturing.

Application

• Crosslinking Agent for Coatings: Used in thermosetting acrylic resins to improve hardness, chemical resistance, and durability of industrial and automotive finishes.
• Hydrophilic Modifier for Adhesives: Imparts moisture compatibility and enhances adhesion to polar substrates in pressure-sensitive and structural adhesive formulations.
• Reactive Diluent & Monomer: Serves as a building block for synthesizing custom acrylic copolymers with tailored properties like flexibility and weatherability.
• Biomedical & Hydrogel Materials: Utilized in the development of contact lenses, wound dressings, and drug delivery systems due to its biocompatibility and water-absorbing characteristics.
• Fiber & Textile Treatment: Applied as a surface modifier to improve dyeability, antistatic properties, and soil release of synthetic fibers.
• Photoresist & Electronic Chemicals: Acts as a component in photopolymerizable resins for printed circuit boards and microelectronics.

Quality Control

Our Poly(Hydroxypropyl Acrylate) is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure consistency in molecular weight distribution, hydroxyl value, viscosity, and residual monomer content. Certificates of Analysis (COA) detailing key parameters are provided with every shipment. We adhere to relevant ISO 9001 standards, and our production can be tailored to meet specific customer requirements for purity and performance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). The product is hygroscopic (moisture-sensitive) and should be kept away from strong oxidizers, acids, and bases. For long-term storage, consider using an inert atmosphere to maintain optimal quality.
