Description

Poly(Propylene Glycol) Acrylate is a reactive, low-viscosity acrylate monomer featuring a polyether backbone. This compound is valued for its ability to impart flexibility, hydrophilicity, and enhanced adhesion properties when copolymerized into various polymer systems. It is essential for formulators and manufacturers in the coatings, adhesives, sealants, elastomers (CASE), and advanced material sectors seeking to modify polymer characteristics.

Application

• UV-Curable Coatings & Inks: A key reactive diluent and crosslinker in formulations requiring fast cure, low shrinkage, and improved flexibility.
• Adhesives & Sealants: Used to enhance the tack, peel strength, and low-temperature performance of acrylic-based pressure-sensitive and structural adhesives.
• Hydrogel Synthesis: Serves as a hydrophilic co-monomer for creating soft, water-absorbent networks used in biomedical and personal care applications.
• Polymer Modification: Incorporated as a functional side chain to introduce polyether segments, improving the impact resistance and compatibility of rigid polymers.
• Lithographic Resins: Employed in the production of photoresists and printing plates for the electronics industry.
• Fiber Optic Coatings: Contributes to the protective, flexible primary coatings applied to optical fibers.

Quality Control

Our Poly(Propylene Glycol) Acrylate is manufactured under a strict quality management system. Each batch is analyzed to ensure consistent monomer purity, functionality, and low levels of residual inhibitors and solvents. Certificates of Analysis (COA) documenting key parameters such as assay, acid value, color, and water content are provided with every shipment.

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). To prevent premature polymerization, maintain under an inert atmosphere if the container is opened and stored for extended periods. Keep away from heat, sparks, and open flame.
