Description

Ethyl α-Chloroacrylate CAS NO 687-46-7 is a versatile and highly reactive ester monomer, a key building block in advanced polymer synthesis. Its primary value lies in its ability to introduce chlorine functionality and cross-linking sites into polymer chains, significantly enhancing material properties such as adhesion, chemical resistance, and durability. This makes it an essential raw material for manufacturers in the coatings, adhesives, and specialty plastics industries seeking to develop high-performance products.

Application

• Reactive Monomer for Acrylic Polymers: Used in the synthesis of specialty acrylic resins for high-performance coatings, paints, and varnishes.
• Adhesive Formulations: Serves as a cross-linking agent in pressure-sensitive and structural adhesives to improve bond strength and environmental resistance.
• UV-Curable Systems: A key component in inks, coatings, and 3D printing resins that cure rapidly under ultraviolet light.
• Fiber Treatment & Textile Chemicals: Imparts water repellency, stain resistance, and durability finishes to synthetic and natural fibers.
• Oilfield Chemicals: Used in the formulation of drilling fluid additives and enhanced oil recovery polymers.
• Photoresist & Electronic Materials: Employed in the production of photoresists and other polymeric materials for the semiconductor industry.
• Impact Modifiers: Incorporated into engineering plastics to improve toughness and impact resistance.
