For professionals in the chemical industry, a deep understanding of material properties is fundamental to successful product development and application. Lauryl Acrylate (LA), identified by its CAS number 2156-97-0, is a prime example of a versatile monomer whose distinct properties drive innovation across various sectors. As a reputable manufacturer and supplier based in China, we aim to provide clarity on this important chemical compound.

Physically, Lauryl Acrylate is described as a clear, colorless liquid. This appearance is advantageous as it does not introduce unwanted color into formulations, which is crucial for applications where visual clarity or specific color matching is required. Its odor is typically characterized as ester-like, which is generally mild and non-offensive. The molecular weight of Lauryl Acrylate is approximately 240.38 g/mol, and it has a density of around 0.87 g/cm³ at 25°C, indicating it is less dense than water.

Chemically, Lauryl Acrylate is an ester of acrylic acid and dodecanol. The presence of the acrylate functional group (-OOC-CH=CH2) signifies its ability to undergo free-radical polymerization. This reactivity is the basis for its widespread use in UV and electron beam (EB) curing technologies, where it polymerizes rapidly to form robust polymer networks. The long, twelve-carbon alkyl chain (lauryl group) is a significant contributor to its hydrophobicity and flexibility. This hydrophobic tail makes the resulting polymers resistant to water and imparts a pliable nature, preventing brittleness.

The primary applications for Lauryl Acrylate stem directly from these properties. It is extensively used as a flexibilizing monomer in UV-curable coatings, inks, and adhesives. By incorporating LA into formulations, manufacturers can achieve improved film flexibility, reduced shrinkage during curing, and enhanced water and weather resistance. For professionals looking to buy Lauryl Acrylate, these specific benefits are key drivers for its selection.

Furthermore, its low viscosity (around 5.0 mPa.s at 20°C) makes it an effective reactive diluent, aiding in the formulation of low-VOC or solvent-free systems, which are increasingly preferred for environmental and safety reasons. This ease of formulation and application is a critical factor for industrial users.

In summary, Lauryl Acrylate is a functional monomer defined by its clear liquid form, ester-like odor, low viscosity, and crucially, its hydrophobic and flexible nature derived from its long alkyl chain. These properties make it an indispensable component for UV-curable coatings, inks, adhesives, and various polymer syntheses.
