Description

Hentriacontyl Methacrylate is a high-molecular-weight methacrylate ester monomer, a key building block for specialty polymers. This long-chain alkyl methacrylate is valued for its ability to impart exceptional hydrophobicity, flexibility, and low surface energy to polymer coatings and materials. It is primarily utilized by formulators and polymer chemists in the production of advanced performance additives, pressure-sensitive adhesives, and surface-modifying resins. The compound, with CAS NO 93857-98-8, is essential for creating materials with tailored properties for demanding industrial applications.

Application

• Performance Additives: Used as a comonomer to synthesize polymeric flow improvers and pour point depressants for fuels and lubricants.
• Specialty Coatings: Imparts water repellency, slip resistance, and mar resistance in industrial, automotive, and protective coatings.
• Adhesive Formulations: Serves as a key monomer in pressure-sensitive adhesives (PSAs) and hot-melt adhesives to enhance tack and low-temperature flexibility.
• Surface Modification: Employed in graft copolymers and surface-active agents to modify the wettability and compatibility of fillers and fibers in composites.
• Release Liners & Films: Used in the production of low-surface-energy polymers for release films and liners.
• Printing Inks: Modifies the rheology and film properties of inks, improving scratch resistance and gloss.
• Personal Care Polymers: A potential ingredient in the synthesis of film-forming agents for hairsprays and cosmetic products.
• Research & Development: A valuable reagent for academic and industrial R&D focused on novel polymer architectures with long alkyl side chains.

Quality Control

Our Hentriacontyl Methacrylate is manufactured under strict quality management protocols. Every batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and Nuclear Magnetic Resonance (NMR), to ensure high purity and consistent performance. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing assay, identity, and impurity profiles. Our quality commitment ensures the material meets the stringent requirements for polymer synthesis and specialty chemical formulation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C/59-77°F). Due to its light-sensitive nature and tendency to be easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
