Description

2-Propenoic Acid, Polymer With α-Hydro-ω-Hydroxypoly[ Oxy(Methyl-1,2-Ethanediyl)] Ether With 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol (3:1) is a specialized polymeric surfactant and rheology modifier, with CAS number 67290-37-3. This compound is engineered to provide exceptional thickening, stabilizing, and emulsifying properties in complex aqueous and solvent-based systems. It is a critical raw material for formulators in the coatings, adhesives, and personal care industries seeking to enhance product performance and stability.

Application

• Coatings & Inks: As a rheology modifier and thickener in waterborne architectural paints, industrial coatings, and printing inks to control viscosity, prevent sagging, and improve application properties.
• Adhesives & Sealants: Used to adjust the flow and build viscosity in acrylic-based pressure-sensitive adhesives (PSAs) and construction sealants, ensuring proper application and bond strength.
• Personal Care Products: Functions as an emulsifier and stabilizer in creams, lotions, and hair care formulations, creating stable emulsions and enhancing sensory feel.
• Industrial & Institutional Cleaners: Acts as a thickening agent and stabilizer in liquid soaps, hard surface cleaners, and detergent formulations to control viscosity and suspend active ingredients.
• Textile & Leather Processing: Employed as a processing aid, thickener for dyes and pigments, and finishing agent to improve handle and performance of treated fabrics and leathers.
• Paper Coatings: Serves as a retention aid and rheology control agent in coating formulations to improve paper gloss, printability, and barrier properties.
