Hexafluoroisopropyl acrylate

CAS: 2160-89-6

Overview

Hexafluoroisopropyl acrylate (CAS 2160-89-6 ) is a fluorinated acrylic monomer used to introduce extreme hydrophobicity, chemical resistance, and low surface energy into polymer systems.

It functions as a reactive building block in specialty coatings, optical materials, and high-performance polymer formulations where standard acrylates cannot meet durability requirements.

In electronics and photonics, it is incorporated into UV-curable resins and optical coatings where low refractive index and moisture resistance are critical performance targets.

Aerospace and defense coating formulators use it to produce films with exceptional resistance to fuels, solvents, and aggressive atmospheric conditions during operation.

In fluoropolymer synthesis, it serves as a comonomer to tune the surface energy and chemical resistance profile of specialty membranes and release coatings for industrial use.

Researchers and industrial formulators also apply it in anti-fouling and hydrophobic surface treatments for substrates requiring durable, low-adhesion finishes and protection.

Hexafluoroisopropyl acrylate is supplied as a liquid monomer, typically with an inhibitor added to prevent premature polymerization during storage and transport phases.

It is available in technical and research-grade specifications, with purity levels commonly ranging from 97% upward for industrial and advanced material applications globally.
