Description

(Hexadecyl)Icosyl Acrylate is a high-molecular-weight acrylate ester monomer, characterized by its long alkyl chain. This structure is crucial for imparting unique properties such as enhanced hydrophobicity, flexibility, and low surface energy to polymer formulations. It is primarily utilized by manufacturers in the polymer and specialty chemical industries seeking to modify the performance characteristics of coatings, adhesives, and lubricant additives.

Application

• Polymer Modification: Acts as a comonomer to introduce long-chain alkyl groups, improving the flexibility, water resistance, and low-temperature performance of acrylic polymers.
• Specialty Coatings & Inks: Used in formulating high-performance, hydrophobic surface coatings, release coatings, and printing inks where slip and mar resistance are critical.
• Pressure-Sensitive Adhesives (PSAs): Incorporated to adjust the viscoelastic properties, tack, and peel strength of acrylic adhesive systems.
• Lubricant & Fuel Additives: Serves as a precursor or intermediate in the synthesis of viscosity index improvers and pour point depressants for industrial lubricants and fuels.
• Surface Active Agents: Utilized in the production of specialty surfactants and emulsifiers for demanding industrial applications.
• Radiation-Curable Resins: A functional monomer in UV-curable formulations for coatings and 3D printing resins, contributing to reduced shrinkage and enhanced elasticity.

Quality Control

Our (Hexadecyl)Icosyl Acrylate is produced under stringent quality management protocols. Each batch is analyzed to ensure it meets precise chemical and physical specifications, including purity, identity, and absence of critical impurities like polymerization inhibitors at specified levels. A comprehensive Certificate of Analysis (COA) detailing assay results, physical properties, and stability data is provided with every shipment to guarantee consistency and support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). To maintain product integrity and prevent premature polymerization, it is recommended to store under an inert atmosphere such as nitrogen and to use appropriate inhibitors as supplied. Keep away from heat, sparks, and open flame.
