Industrial Applications of 1,4-Butanediol dimethacrylate
| Industry | Application | Process |
|---|---|---|
| Coatings & Inks | Used as a crosslinker and reactive diluent to enhance coating hardness, abrasion resistance, and adhesion | Applied in ultraviolet (UV) curing systems; copolymerized with acrylate monomers and cured via UV-induced free-radical polymerization |
| Adhesives | Improves bond strength and heat resistance in high-performance structural adhesives | Employed as a difunctional monomer in photopolymerization or thermal curing systems; mixed with prepolymers and cured to form the final product |
| Photocurable Resins | Used as a highly reactive monomer to improve cure speed and crosslink density | Formulated as a comonomer in acrylate-based photocurable resins; participates in free-radical polymerization |
| 3D Printing (Photocuring) | Functions as a component of photosensitive resins to improve mechanical properties and dimensional stability of printed parts | Blended with prepolymers such as urethane acrylates; cured into final shape via stereolithography (SLA) or digital light processing (DLP) |
| Electronic Encapsulation Materials | Used to formulate low-shrinkage, high-heat-resistance encapsulants and insulating coatings | Incorporated into UV-curable encapsulant resin formulations; crosslinked and cured via photoinitiator-triggered reactions |
Manufacturing Quality Control of 1,4-Butanediol dimethacrylate
| Test Item | Common Test Methods | Method Overview |
|---|---|---|
| Purity (Main Component Content) | Gas Chromatography (GC) | The sample components are separated using a capillary chromatographic column. The BDDMA main peak area is quantified using an FID detector. Purity is calculated by internal or external standard method, with accuracy above 99%. |
| Acid Value (Free Acid Content) | Acid-Base Titration (GB/T 1668-2008) | Free carboxylic acids in the sample are titrated with potassium hydroxide ethanol solution, using phenolphthalein as indicator. Acid value (mg KOH/g) is calculated to evaluate acidic impurity content. |
| Peroxide Content | Iodometric Method or Colorimetry | Peroxides oxidize potassium iodide to release iodine under acidic conditions. The iodine is titrated with sodium thiosulfate, or measured by colorimeter to ensure no residual polymerization initiator remains. |
| Water Content | Karl Fischer Titration (KF Method) | Trace moisture is measured using Coulometric or Volumetric Karl Fischer reagent. Moisture is controlled to <0.1% to prevent runaway polymerization or hydrolysis during storage. |
| Appearance and Color | Visual Color Comparison / ASTM D1209 | Check if the sample is clear and colorless. A platinum-cobalt colorimeter is used to measure color number. Color should be ≤10 Hazen to ensure absence of degradation or oxidation products. |
| Density | Density Meter / Pycnometer Method (GB/T 4472) | Density is measured at 25°C using a digital density meter or pycnometer. Typical value is about 1.03–1.05 g/cm³, used as an auxiliary indicator for purity assessment. |
| Refractive Index | Refractometry (GB/T 6488) | The refractive index (nD²⁰ ≈ 1.470–1.475) is measured at 20°C or 25°C using a digital refractometer, as a rapid indicator for purity and batch consistency. |
| Volatile Matter / Residue | Loss on Drying Method (GB/T 6283) | The sample is dried at 105°C to constant weight to measure volatile components and non-volatile residue. Residue is controlled to ≤0.1% to assess impurities or polymer residues. |
| Acrylate Monomer Residue (Methacrylic Acid) | High-Performance Liquid Chromatography (HPLC) | Residual unreacted methacrylic acid monomer is detected using a C18 reverse-phase column and UV detector (210–220 nm). Residue is controlled to <50 ppm to ensure safety and polymerization control. |
| Thermal Stability (TGA) | Thermogravimetric Analysis (TGA) | The sample is heated under nitrogen atmosphere (e.g., 25–300°C), and the mass loss curve is monitored to evaluate the onset of thermal decomposition and presence of low-boiling impurities or decomposition products. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, lead, cadmium, mercury and other heavy metal contents are measured to meet RoHS or REACH standards (e.g., Pb <1 ppm), for control in electronics/medical grade products. |
