Molecular Structure：
SINOMER®CHA is an important monofunctional acrylate monomer, whose molecular structure consists of an active acrylate double bond and a rigid cyclohexyl group. This unique structure endows it with multiple key functions. As a reactive monomer, its double bonds in the molecule are very active and can easily undergo polymerization reactions with other acrylic or vinyl monomers under heating, light, or the presence of initiators. Introducing rigid functional groups: After polymerization, the cyclohexyl group on the molecule will be introduced into the polymer, as its cyclic structure brings hardness, strength, and good glossiness.

Q1: What is Cyclohexyl Acrylate and its relationship with related chemicals?
A: Cyclohexyl Acrylate (CAS 3066-71-5), SINOMER® CHA, is a functional acrylic monomer featuring a cyclohexyl ester ring structure. In the family of functional acrylates and related chemicals, its chemical structure sits between linear alkyl acrylates and aromatic monomers. This distinctive build allows it to impart a perfect balance of hardness, scratch resistance, and low shrinkage into copolymer formulations without adding brittle aromatic traits.
Q2: What are the common industrial uses of Cyclohexyl Acrylate?
A: The main industrial uses of Cyclohexyl Acrylate center around radical polymerization and UV curing technologies. It is widely used as a premium reactive monomer in UV-curable coatings, overprint varnishes, and electronic inks. It is also a core ingredient in engineering acrylic adhesives and synthetic resins to improve water resistance, optical clarity, and thermal stability.
Q3: Where can I find high-quality Cyclohexyl Acrylate for industrial and research purposes?
A: You can contact us - Sinocure. Our brand SINOMER® CHA guarantees factory-direct pricing, high purity, and stable inhibitor controls. We accommodate flexible volume requirements—ranging from experimental trial samples to multi-ton container shipments.
Q4: Are there any safety concerns or specific handling tips for Cyclohexyl Acrylate?
A: Yes. Cyclohexyl Acrylate is a combustible liquid that can cause skin irritation, serious eye irritation, and skin sensitization. To ensure safe operation, it must be handled under adequate ventilation using personal protective equipment (PPE), such as nitrile gloves and chemical safety goggles. Additionally, as a critical handling tip, never store this monomer under an inert gas (like pure nitrogen), because the built-in stabilizer (MEHQ) requires dissolved oxygen to prevent premature, hazardous polymerization. Full instructions are available in our GHS-compliant Safety Data Sheet (SDS). You can contact us.
