Full Description

Butyl acrylate (CAS 141-32-2) is the n-butyl ester of acrylic acid, a reactive monomer. It is used to produce coatings, inks, adhesives, sealants, textiles, plastics, and elastomers, including architectural latex coatings and pressure-sensitive adhesives. It is a comonomer for solvent- and water-based polymer dispersions.

Frequently Asked Questions

What is butyl acrylate used for?

Butyl acrylate (BA, CAS 141-32-2) is a reactive acrylic monomer used to produce coatings, inks, adhesives, sealants, textiles, plastics, and elastomers. It is a key comonomer in architectural latex coatings, pressure-sensitive adhesives, and solvent- and water-based polymer dispersions.

What is butyl acrylate made from?

Butyl acrylate is the n-butyl ester of acrylic acid (C7H12O2), produced by esterifying acrylic acid with n-butanol. As a monomer it is polymerized or copolymerized into emulsion and solvent-based resins.

What is the CAS number and molecular formula of butyl acrylate?

Butyl acrylate has CAS number 141-32-2 and molecular formula C7H12O2. It is supplied as a stabilized monomer for (co)polymerization.

What is the UN/DOT shipping number for butyl acrylate?

Butyl acrylate ships under UN 2348 (butyl acrylate). The SDS and shipping documentation specify packing group, labeling, and required inhibitor; confirm transport requirements with your carrier.

What is the price of bulk butyl acrylate?

Butyl acrylate pricing tracks order volume, packaging, and market conditions, so RawSource quotes it per order rather than as a fixed price. Submit a bulk RFQ with your target quantity to receive current pricing and lead time; a CoA and SDS accompany each shipment.
