1,3-Butanediol Diacrylate carries the chemical formula C10H14O4 and brings the combined structure of a diol and acrylate into one compound, making it a key raw material in resin production and certain specialty polymers. This chemical usually takes the form of a clear liquid, but under cold storage, crystalline bits settle at the bottom before returning to their liquid state. At room temperature, it's neither chalky powder nor sticky flakes; think of a transparent syrup with a distinguishable sharp, acrylate-like odor. The density gets measured near 1.07 g/cm³ at 20°C. People in manufacturing call it a monomer, referring to its dual unsaturated acrylate groups linked by a butanediol bridge, providing both flexibility and reactivity in crosslinking reactions.
Most production lines treat 1,3-Butanediol Diacrylate as a liquid material, thanks to its low melting point and straightforward mixing with other acrylates. It holds a boiling point just above 240°C and a flash point near 110°C, which means it doesn't evaporate quickly but can catch fire under certain process conditions. Its two acrylate ends let it connect with other molecules, forming strong networks in cured resins. This property raises its value in UV-curing inks, paints, and advanced dental or medical composites, where a sturdy matrix is more than a desire—it's essential. The HS Code assigned to it is 2916.19, coming under acyclic polycarboxylic acids, which customs officers recognize with ease.
The backbone of 1,3-Butanediol Diacrylate consists of a four-carbon chain (butane structure) with two hydroxyl groups replaced by acrylate esters. Its molecular layout gives both flexibility and a clear site for polymerization. If someone ever tried to convert it into a solid, they'd freeze it or dehydrate it, but this only happens in labs, not in factories or bulk shipping barrels. The liquid state not only simplifies storage and metering, it helps in dissolving photoinitiators for coating makers. Every drum or bottle usually shows batch numbers, molecular weight (198.22 g/mol), and exact density, helping factories stick to their recipes and avoid costly mistakes in finished goods. Additives and stabilizers sometimes get blended in to lengthen shelf life, which everyone appreciates, especially those who only open new supplies every few weeks.
No one in my line of work skips over the Material Safety Data Sheet (MSDS) warnings for 1,3-Butanediol Diacrylate. Skin contact or inhaling the vapor brings health risks, ranging from irritation to headaches. Direct exposure sometimes triggers allergic reactions—red, itchy skin and watery eyes are common complaints among unprotected workers. While the liquid doesn't jump into flames on its own, a nearby spark or hot metal surface turns it hazardous thanks to that flash point. Proper ventilation, chemical gloves, and face shields come out every time it's handled, and disposal goes through high-temperature incineration or licensed chemical waste handlers. Environmental laws require that any spills stay contained to avoid pollution in water streams, for both worker safety and community protection. Long-term, companies look for closed systems and safe substitutes that offer the same reactive punch but lower toxicity, keeping with demands from workplace health advocates and regulators.
As the market leans toward products that balance high performance and safe handling, documentation for 1,3-Butanediol Diacrylate grows ever more detailed. EU REACH registration, RoHS compliance, and regular testing for purity and impurities appear in every procurement contract. Factories keep records of every batch, tracking lot numbers and source suppliers to guarantee consistent quality. Changes in regulatory policies force annual reviews and updates to protocols, often involving external auditors who check everything from shipment labeling to the conditions inside production plants. These quality safeguards don't just protect workers at the plant—they also provide confidence for big end-users, whether they're producing electronics, adhesives, or next-generation coatings. This kind of transparency and vigilance safeguards both reputation and public health, underlining why every detail, from molecular structure to MSDS filing, deserves careful attention.
