Description

n-Propyl Methacrylate is a versatile methacrylate ester monomer essential for creating high-performance polymers and copolymers. Its primary value lies in imparting flexibility, weatherability, and excellent adhesion properties to the resulting materials. This product is a critical raw material for manufacturers in the coatings, adhesives, and specialty plastics industries seeking to enhance product durability and performance.

Application

• Acrylic Resin Synthesis: A key monomer for producing acrylic and methacrylic resins used in automotive, industrial, and architectural coatings.
• Adhesive Formulations: Used to develop pressure-sensitive adhesives (PSAs) and structural adhesives with improved flexibility and bond strength.
• Specialty Polymers: Serves as a co-monomer in the production of impact modifiers, processing aids, and other functional polymer additives.
• UV-Curable Systems: An important component in inks, coatings, and 3D printing resins that cure rapidly under ultraviolet light.
• Fiber Treatment: Employed in the surface modification of textiles and fibers to enhance dyeability and water repellency.
• Dental & Medical Materials: Used in the formulation of dental composites and bone cements due to its biocompatibility and polymerization characteristics.

Quality Control

Our n-Propyl Methacrylate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) for each lot, detailing key parameters such as assay, purity, and inhibitor content. Our quality commitment aligns with industrial best practices, and we can support compliance requirements for specific applications upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources, strong acids, and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). The product typically contains an inhibitor (e.g., MEHQ) to prevent premature polymerization; storage conditions must be maintained to preserve inhibitor efficacy.
