Is n-Butyl Acrylate the same as 2-Ethylhexyl Acrylate?

No. They are different acrylic monomers and can produce different polymer balances. The monomer choice should follow the required polymer design, co-monomers and final formulation rather than a name-based substitution.

Which n-Butyl Acrylate points should be specified before production use?

Confirm assay, water, inhibitor type or level, packing and the intended storage period. The offered batch COA should be reviewed against the agreed specification before the monomer is charged to the process.

Why is inhibitor information relevant for n-Butyl Acrylate?

Acrylic monomers require controlled inhibitor conditions during storage and handling to reduce the risk of unintended polymerisation. The required inhibitor condition should be agreed with the planned process and checked against the supplied SDS.

n-Butyl Acrylate (BA) CAS 141-32-2

n-Butyl Acrylate (BA), CAS 141-32-2, also known as butyl 2-propenoate, is an acrylic monomer for polymer dispersions used in industrial adhesives, waterborne coatings, construction sealants and coating binders. 2-Ethylhexyl Acrylate is a related soft acrylic monomer for copolymer selection. It is selected at the polymer-manufacturing stage according to the monomer balance, co-monomers and inhibitor condition. COA, TDS and SDS are available for the offered batch; assay, water, inhibitor level and packing are agreed for the intended process.

3 Order Specification and Documentation

Product Introduction

n-Butyl Acrylate (BA) (CAS 141-32-2) is a stabilized acrylic monomer for emulsion and solution-polymer manufacture. The listed material is used as a soft-monomer component in acrylic systems for adhesives, coatings and binders; it is a reactive raw material, not a finished acrylic resin, dispersion or adhesive.

Applications

Acrylic pressure-sensitive adhesive and tape formulations
Waterborne and solvent-borne acrylic coating polymers
Polymer emulsions for paper, textile and construction binders
Sealant and elastomer-modified acrylic copolymer systems

Order Specification and Documentation

An n-butyl acrylate order is matched to the intended polymer route. The agreed specification can include monomer assay, inhibitor system, colour, water and acid value, with packaging selected for the required handling and production schedule. A batch COA, together with the applicable TDS and SDS, is available for the quoted BA monomer grade.

For related acrylic ester monomers with different alkyl groups, compare Ethyl Acrylate, 2-Ethylhexyl Acrylate, and Isobutyl Acrylate.
