Description
1,4-Butanediol diacrylate (CAS 1070-70-8) is a difunctional acrylate monomer commercially known under trade names including SR 213. It carries the molecular formula C10H14O4 and is also referenced as 1,4-butylene diacrylate or tetramethylene diacrylate in supplier and regulatory documentation.
In UV- and peroxide-cured polymer systems, it functions as a crosslinker by reacting through both acrylate end groups to form tightly networked polymer chains, increasing hardness and solvent resistance in coatings and adhesives. In printing and packaging applications, it contributes to ink film integrity by controlling cure speed and crosslink density during radiation curing.
Supplied as a liquid under HS code 29161290 and subject to REACH registration requirements within the EU, this material is available in standard industrial drum and IBC formats. No E-code or Ph.Eur. designation applies. Buyers should confirm inhibitor levels and purity grade against their specific formulation requirements prior to ordering.
