Description

2-Methylpentyl Acrylate is a versatile acrylate ester monomer characterized by its branched alkyl chain. This compound is a crucial building block in polymer chemistry, valued for its ability to impart flexibility, low-temperature performance, and enhanced hydrophobicity to copolymer systems. It is primarily sought by manufacturers in the coatings, adhesives, and specialty polymers industries for developing advanced materials with tailored properties.

Application

• Pressure-Sensitive Adhesives (PSAs): Imparts low glass transition temperature (Tg) and improved tack for labels and tapes.
• Coatings and Paints: Used as a co-monomer to enhance flexibility, weatherability, and water resistance in acrylic resins.
• Textile and Leather Finishes: Modifies polymer backbones to create soft, durable, and water-repellent finishes.
• Acrylic Fiber Modification: Incorporated to improve dyeability and the tactile properties of synthetic fibers.
• Sealants and Caulks: Contributes to elasticity and long-term durability in construction and industrial sealants.
• UV-Curable Resins & Inks: Serves as a reactive diluent or functional monomer in fast-curing formulations.

Quality Control

Our 2-Methylpentyl Acrylate is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing to ensure consistent purity, identity, and performance. A detailed Certificate of Analysis (COA) confirming specifications for assay, purity, and critical impurities is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its light-sensitive and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents and initiators.
