Description

Hentriacontyl Acrylate is a high-molecular-weight acrylate ester monomer, a key building block for specialty polymers. This long-chain acrylate is valued for its ability to impart unique properties such as hydrophobicity, flexibility, and low surface energy to polymer chains. It is essential for R&D and production in advanced material science, serving industries that require tailored performance from coatings, adhesives, and functional additives.

Application

• Specialty Polymer Synthesis: As a comonomer for creating high-performance acrylic resins with enhanced film-forming and mechanical properties.
• Surface Coatings & Inks: Imparts water resistance, durability, and specific rheological characteristics to industrial and protective coatings.
• Pressure-Sensitive Adhesives (PSAs): Used to modify tack, peel strength, and cohesion in adhesive formulations.
• Lubricant & Fuel Additives: Serves as a precursor for viscosity index improvers and pour-point depressants.
• Textile & Fiber Treatment: Employed in coatings to provide water-repellent and softening finishes.
• Release Coatings & Mold Agents: Contributes to non-stick and easy-release properties in various manufacturing processes.
