Tetramethylene glycol diacrylate

Tetramethylene glycol diacrylate (CAS 1070-70-8 ), commercially abbreviated as BDDA, is a bifunctional acrylate monomer derived from 1,4-butanediol. It functions as a reactive crosslinker and diluent in UV- and peroxide-curable polymer systems. This monomer is essential for building network density and improving mechanical performance in cured materials. In UV-curable coatings and printing inks, BDDA controls viscosity while contributing to crosslink density. These properties directly affect cure speed and film hardness in industrial applications. Adhesive and sealant formulators use it to tune flexibility and cohesive strength in radiation-cured systems where elongation is critical. In plastics and polymer manufacturing, it acts as a crosslinking agent during polymerization to modify gel content. This modification improves the swelling resistance and dimensional stability of the final material produced. Personal care applications include its use as a crosslinker in gel-forming polymer networks. In these formulations, the network tightness determines the specific texture and product consistency required for the consumer. BDDA is supplied as a clear liquid, typically with inhibitor added to prevent premature polymerization during storage and transport. Technical and industrial grades are the standard commercial offering for this chemical. Purity levels are commonly specified at 98% or higher to ensure consistent performance in sensitive reactions. Packaging ranges from drums to IBC containers depending on the specific order volume and logistics needs. Contact us for supply of Tetramethylene glycol diacrylate Request Quote
