Description

Poly(n-Octyl Methacrylate) is a high molecular weight polymer derived from the esterification of methacrylic acid with n-octanol. This compound is valued for its excellent hydrophobic properties, low glass transition temperature (Tg), and compatibility with a wide range of organic materials, making it a versatile performance additive. It is primarily utilized in industries requiring durable, flexible, and water-resistant polymer modifications, such as coatings, adhesives, and specialty plastics.

Application

• As a key modifier in pressure-sensitive adhesives (PSAs) and sealants to enhance tack, flexibility, and water resistance.
• As a plasticizer and flow improver in industrial and automotive coatings to improve film formation and durability.
• In the formulation of printing inks and overprint varnishes to provide gloss and abrasion resistance.
• As a compatibilizer and impact modifier in engineering plastics and rubber compounds.
• For the production of specialty lubricant additives and grease thickeners.
• In the research and development of controlled-release drug delivery systems and biomedical materials.
