Description

Poly(n-Decyl Methacrylate) is a high molecular weight polymer belonging to the family of long-chain alkyl methacrylates. This compound is valued for its ability to impart excellent low-temperature flexibility, hydrophobicity, and internal plasticization to polymer systems. It serves as a crucial performance additive and co-monomer for advanced material formulations in industries requiring durable, weather-resistant, and low-tack properties. Key sectors utilizing this specialty polymer include coatings, adhesives, lubricants, and personal care product development.

Application

• Coatings & Paints: Used as a modifying resin to enhance flexibility, water repellency, and low-temperature film formation in industrial, marine, and architectural coatings.
• Adhesives & Sealants: Acts as a tackifier and plasticizer to improve adhesion, cohesion, and elasticity in pressure-sensitive and structural adhesive formulations.
• Lubricant & Grease Additives: Functions as a viscosity index improver and pour point depressant in synthetic lubricants and high-performance greases.
• Personal Care & Cosmetics: Employed as a film-forming agent and texture enhancer in nail polishes, hair styling products, and sunscreens.
• Plastic & Rubber Modification: Incorporated as a co-monomer to improve the impact resistance, processability, and weatherability of acrylic plastics and synthetic rubbers.
• Printing Inks: Utilized to adjust rheology, gloss, and substrate adhesion in specialty printing ink systems.
