Description

2-(Ethylthio)Ethyl Acrylate is a specialized acrylate monomer featuring a sulfur-containing ethylthioether side chain. This unique structure imparts valuable properties such as enhanced adhesion, flexibility, and chemical resistance to polymers, making it a critical intermediate for high-performance materials. It is primarily sought by formulators and manufacturers in the coatings, adhesives, and specialty polymer industries for developing advanced products.

Application

• UV-Curable Coatings and Inks: Acts as a reactive diluent and crosslinker to improve cure speed, adhesion to low-surface-energy substrates, and chemical resistance.
• Pressure-Sensitive Adhesives (PSAs): Incorporated to modify tack, peel strength, and cohesion, particularly for applications requiring oil or solvent resistance.
• Specialty Acrylic Resins: Used as a co-monomer to synthesize polymers with specific properties like low-temperature flexibility, weatherability, and reduced moisture vapor transmission.
• Fiber Optic Coatings: Employed in formulations where specific refractive index adjustments and enhanced mechanical protection are required.
• Photopolymer Printing Plates: Serves as a key component to achieve desired elasticity, swell resistance, and fine image reproduction.
• Modifier for Rubber and Elastomers: Used to graft onto polymer backbones to improve oil and heat resistance.

Quality Control

Every batch of 2-(Ethylthio)Ethyl Acrylate is produced and tested under a strict quality management system. We ensure consistent purity and performance through comprehensive analytical methods including Gas Chromatography (GC) and titration. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications for identity, assay, and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). This product is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) when in partially used containers to maintain stability and prevent polymerization. Keep away from heat, sparks, and open flame.
