Description :

Overview of Stearyl Acrylate

Stearyl Acrylate is a long-chain alkyl acrylate monomer widely used in polymer and copolymer manufacturing to impart hydrophobicity, flexibility, and surface modification properties. Due to its long stearyl side chain, it provides wax-like characteristics, improved slip, and enhanced water resistance in finished polymer systems.

In industrial applications, Stearyl Acrylate is commonly referred to as long-chain acrylate monomer, alkyl acrylate, or hydrophobic acrylate. Its ability to modify surface behaviour and rheological properties makes it a valuable component in speciality polymers, coatings, and functional material formulations.

Application of Stearyl Acrylate

Polymer Modification & Speciality Copolymer Systems

Stearyl Acrylate is extensively used as a comonomer in polymer and copolymer systems where surface slip, flexibility, and hydrophobic performance are required. Its long alkyl chain reduces intermolecular friction and contributes to improved softness and surface smoothness in polymer films and moulded materials.

In such systems, Stearyl Acrylate is often copolymerized with materials such as Methyl Acrylate and Butyl Acrylate to balance hardness, flexibility, and surface properties. These applications are closely aligned with requirements in polymers, where tailored surface behaviour and processing efficiency are critical.

Coatings, Surface Treatment & Functional Finishes

Stearyl Acrylate plays an important role in coatings and surface treatment formulations by enhancing water repellency, slip characteristics, and resistance to blocking. It contributes to smooth film formation and improves surface durability in speciality coatings.

In coating systems, it may be used together with Acrylic Emulsion to achieve controlled rheology and surface performance. These applications are strongly associated with coatings and plastics, where surface quality, moisture resistance, and long-term appearance are essential.

Lubricity, Slip Additive & Speciality Industrial Uses

Stearyl Acrylate is also used in speciality industrial formulations where internal lubrication, slip behaviour, and anti-blocking performance are required. It helps reduce friction between surfaces and improves processing behaviour in polymer compounding and film applications.

Depending on formulation needs, it may be selected to complement other long-chain acrylates or wax-based additives to achieve specific functional outcomes. These applications support industries requiring controlled surface modification and stable performance under processing conditions.
