Description

Polyethylmethacrylate CAS NO 197098-43-4 is a synthetic polymer belonging to the acrylate ester family, known for its excellent film-forming properties, clarity, and durability. This material is valued for its ability to form tough, transparent coatings and films with strong adhesion to various substrates. It is a critical component for formulators and manufacturers in the coatings, adhesives, and specialty plastics industries seeking to enhance product performance and longevity.

Application

• Industrial and Protective Coatings: Used as a primary film-forming agent in solvent-based and waterborne coatings for metal, wood, and plastic, providing excellent gloss, weather resistance, and chemical protection.
• Adhesives and Sealants: Serves as a key polymer in pressure-sensitive adhesives (PSAs), structural adhesives, and caulks, offering strong bonding strength and flexibility.
• Printing Inks: Acts as a resin binder in specialty printing inks, contributing to fast drying times, rub resistance, and vibrant color development.
• Plastic Modifiers and Impact Improvers: Utilized as an additive to modify the properties of other polymers, enhancing impact resistance, processability, and surface characteristics.
• Leather and Textile Finishes: Applied in topcoat formulations for leather and fabric to provide a durable, flexible, and water-resistant finish.
• Optical Materials: Employed in the production of transparent sheets, light guides, and other optical components due to its high clarity and light transmission properties.
