1,10-Decanediol Diacrylate runs under the chemical formula C16H26O4. The compound carries a molecular weight of roughly 282.38 g/mol. This material stands out as a specialized diacrylate ester designed for advanced polymer synthesis and crosslinking activities in coatings, adhesives, inks, and engineered polymers. Production uses 1,10-decanediol as the backbone, joined with acrylate groups on each end. That molecular structure supplies more flexibility than short-chain analogs while still giving solid crosslinking through those reactive acrylate groups. You’ll find it sometimes listed under the HS Code 2916.12, covering acrylic esters in international shipments. Chemically, it falls in the category of diacrylates, which often appear as essential raw materials for UV-curing resins and industrial coatings.
On first look, 1,10-Decanediol Diacrylate can appear as a transparent, slightly viscous liquid at room temperature, but its physical state could shift to a waxy solid or even crystalline flakes in cooler environments. This duality lends itself to a wide range of industrial processing options. Typical density averages near 1.01–1.03 g/cm³, with slight variation as temperature and purity grade come into play. The refractive index hovers close to 1.450, making visual clarity an important quality. As a liquid monomer, it pours smoothly for bulk mixing, yet at lower temperatures, users might run into solidified pearls or flakes, indicating clean crystallization that points to high material quality. In powder form, the substance resists easy handling due to its oily nature—most operations favor the liquid solution, ensuring good dispersion in blending and lowering dust-related exposure risk.
Looking at its molecular structure, 1,10-Decanediol Diacrylate draws on a decane chain linking two acrylate end groups. Those carbon-carbon double bonds at each end act as reactive points during free radical polymerization. The formula C16H26O4 visually splits into an aliphatic decane core (ten carbons) separated by two ester bridges, each topped with a vinyl acrylate. This structure pushes the compound toward flexibility—an advantage compared with shorter diacrylate molecules, which lead to more brittle cured products. The balance between chain length and functionality supports tough, flexible elastomers while promoting strong internal cohesion in a cured state.
Manufacturers supply this diacrylate across a few standard formats: bulk liquid in drums or IBCs, and for some niche needs, melted flakes, semi-solid pearls, or powder grades for specialty compounding. Most industry users go with the liquid version, ordered by the liter or ton. Typical purity levels climb past 98 percent, as trace moisture or impurities damage the fast, photoinitiated reactions central to UV-curable systems. Professionals keep an eye on acid value, as well as color (APHA/Hazen scale) to judge suitability for clear, colorless films. Material safety data sheets will confirm volatility, vapor pressure, and flash point. Standard flash point exceeds 100°C, so spontaneous ignition poses less worry during routine storage, although adequate ventilation always belongs near open handling.
Safety never takes a back seat with highly functional acrylates. 1,10-Decanediol Diacrylate rates as a skin and eye irritant, with the possibility of sensitization if exposure repeats often. Gloves, goggles, and good local ventilation fit as default PPE inside the lab or factory. Storage assigns primary importance to keeping containers sealed, cool, and away from UV exposure—sunlight might kick off unwanted polymerization in the drum. Spills should be handled with absorbent pads and must never meet open drains. Regulation classifies many acrylates under hazardous raw materials, flagged for their potential to cause both acute irritation and long-range allergy in unprotected workers. Any signage ought to communicate both harmful potential and proper first aid for splashes. Fire risk does not challenge many sites, yet chemical fume resistance in construction materials remains a sound choice for long-term tank storage. Most handling incidents trace back to neglecting either splash protection or clean containment of fine powder residues.
You find 1,10-Decanediol Diacrylate as a backbone for developing flexible yet durable photopolymers, especially in 3D printing, electronics encapsulation, and protective automotive or flooring coatings. Its long-chain diol component pushes final cured material to stretch further before failure, resisting cracking or stress-induced breakage. Some companies select it to fine-tune flexibility within copolymer blends, carving out a niche for solvent-free, low-smoke curing systems that meet increasingly strict VOC rules. Custom ink and varnish formulators tap into its low yellowing rate, using the clear, liquid state for easy incorporation during bulk mixing. Powder and pearl variants show up most often in dry blend premixes, though hygroscopic pickup needs constant humidity control. As a raw material, every batch must deliver high acrylate purity and moisture content below 0.1 percent; even minor contamination can stall or misbuild the fast-curing polymer network. Crossover with other diacrylates remains limited, as the C10 chain guarantees unique flexibility and process balance not matched by shorter or more branched forms.
Being a synthetic acrylate ester, 1,10-Decanediol Diacrylate falls under chemical inventories like REACH in the EU, TSCA in North America, and similar lists in Asia. Manufacturers face annual scrutiny over emissions and responsible waste control, since residual monomer streams can burden air and water paths if controls slip. I’ve seen careful users invest in closed transfer lines and advanced vapor recovery to keep personal exposure below regulatory thresholds. Disposal routes rely on specialist chemical incineration, while recycling solvents calls for solid technical management to avoid trace contamination of new batches. Users who run large-scale compounding lines cannot ignore ongoing responsibility for transparent reporting and material declarations down the supply chain. Early preparation and rigorous chemical stewardship always pay off by sidestepping accidental releases or regulatory fines linked to improper handling.
