Description

Poly(Hexadecyl Methacrylate) is a high molecular weight polymer derived from the esterification of methacrylic acid with cetyl alcohol. This long-chain alkyl methacrylate polymer is valued for its excellent hydrophobic properties, low glass transition temperature, and compatibility with various organic matrices. It is primarily utilized as a key additive and modifier in specialty coatings, lubricants, and personal care formulations where surface modification, internal lubrication, and water resistance are critical performance factors.

Application

• Internal Lubricant and Processing Aid for engineering plastics and rubber compounds to improve flow and mold release.
• Hydrophobic Additive in architectural and industrial coatings to enhance water repellency and surface protection.
• Viscosity Index Improver and Pour Point Depressant in synthetic lubricants and greases.
• Textile and Fiber Treatment agent to impart softness, water resistance, and anti-static properties.
• Modifier for Pressure-Sensitive Adhesives (PSAs) to adjust tack, peel strength, and cohesion.
• Additive in Personal Care Products such as hair styling agents and skincare formulations for film-forming and conditioning effects.
• Component in Ink and Toner Formulations to control rheology, gloss, and adhesion.
• Release Agent and Anti-blocking Agent in polymer films and packaging materials.
