Description

2-Cyclohexylpropan-2-Yl Methacrylate CAS NO 186585-56-8 is a specialized methacrylate monomer featuring a bulky cyclohexyl-substituted tertiary butyl group. This unique sterically hindered structure is engineered to impart exceptional properties such as enhanced hydrophobicity, improved thermal stability, and reduced polymer chain mobility in the resulting copolymers. It is a critical building block for advanced material scientists and polymer formulators seeking to develop high-performance coatings, adhesives, and specialty resins with tailored characteristics for demanding industrial environments.

Application

• High-Performance Coatings: Used as a co-monomer to formulate automotive clear coats, industrial maintenance paints, and marine coatings requiring superior weatherability, chemical resistance, and low moisture absorption.
• Advanced Adhesives & Sealants: Imparts enhanced flexibility, adhesion to low-energy surfaces, and durability in pressure-sensitive adhesives (PSAs), structural adhesives, and construction sealants.
• Specialty Polymer Modifiers: Serves as a key monomer for synthesizing impact modifiers, processing aids, and compatibilizers to improve the toughness and processability of engineering plastics.
• Optical and Electronic Materials: Employed in the production of optical lenses, light-guiding plates, and photoresist materials where high purity and controlled refractive index are paramount.
• Hydrophobic Surface Treatments: A precursor for creating water-repellent and anti-fouling surface coatings for textiles, membranes, and construction materials.
• UV/EB Curable Systems: An effective reactive diluent and crosslinker in ultraviolet (UV) or electron beam (EB) curable inks, varnishes, and 3D printing resins.

Quality Control

Our production of 2-Cyclohexylpropan-2-Yl Methacrylate adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets precise customer specifications and consistent lot-to-lot performance. Certificates of Analysis (COA) detailing all critical parameters are provided and can be tailored to support compliance with REACH, ISO, and other relevant regulatory frameworks for global supply.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat, sparks, and open flame. Due to its reactivity with strong acids and solubility in organic solvents, ensure segregation from incompatible materials. For long-term storage under an inert atmosphere such as nitrogen, please contact our technical team for specific recommendations.
