Description

Methyl Vinyl Ether-Monoethyl Maleate Copolymer is a synthetic polymer formed from the copolymerization of methyl vinyl ether and monoethyl maleate. This versatile material is valued for its film-forming, adhesive, and thickening properties, making it a key functional additive in various industrial formulations. It is primarily utilized by manufacturers in the pharmaceutical, personal care, and specialty coatings industries seeking consistent performance and regulatory compliance.

Application

• Pharmaceutical Coatings: Used as a film-forming agent in enteric and sustained-release tablet coatings.
• Personal Care Products: Acts as a stabilizer, thickener, or film-former in hair sprays, mousses, and skin care formulations.
• Adhesive Formulations: Serves as a tackifier and modifier in pressure-sensitive and specialty adhesives.
• Industrial Coatings: Functions as a binder or additive to modify the rheology and film properties of specialty paints and coatings.
• Textile Processing: Employed as a sizing agent or finishing aid to improve fabric handle and performance.
• Printing Inks: Used to adjust viscosity and enhance the gloss and adhesion properties of inks.

Quality Control

Our Methyl Vinyl Ether-Monoethyl Maleate Copolymer is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for viscosity, solids content, residual monomers, and other critical parameters. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
