Description

Pentaerythritol Diacrylate Monostearate is a specialized multifunctional monomer that combines the properties of an acrylate and a fatty acid ester. This unique structure is critical for formulating advanced materials requiring a balance of reactivity, cross-linking density, and hydrophobic modification. It is primarily sought by industrial manufacturers developing high-performance, radiation-curable coatings, inks, and adhesives where enhanced surface properties and durability are essential.

Application

• UV/EB Curable Coatings: A key component in formulations for wood, plastic, and metal coatings, providing excellent cure speed, hardness, and chemical resistance.
• Printing Inks: Used in energy-curable inks for packaging and publications to improve adhesion, gloss, and rub resistance.
• Adhesives & Sealants: Imparts internal flexibility and water resistance in radiation-cured adhesive systems.
• Optical Fiber Coatings: Contributes to the protective secondary coating, offering low shrinkage and good mechanical properties.
• Dental Composites: Acts as a reactive diluent and cross-linker in light-curable restorative materials.
• Release Coatings & Overprint Varnishes: Enhances surface slip and release characteristics in specialized industrial coatings.

Quality Control

Our Pentaerythritol Diacrylate Monostearate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including assay, impurity profiling, and physical property verification, to ensure consistency and performance. A Certificate of Analysis (COA) detailing purity, color, acid value, and other critical parameters is provided with each shipment to guarantee compliance with your technical requirements.

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). This product is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) after opening to maintain purity and prevent polymerization. Keep away from heat sources and incompatible materials.
