Store below 25 °C in original light-protective container, away from oxidizers, peroxides and strong acids. Avoid prolonged exposure to ambient daylight in the workshop. Shelf life 24 months unopened. Re-seal under nitrogen for opened drums to minimise moisture pickup.
Other grades of this compound
Same chemistry (CAS 119313-12-1), different purity / packaging.
Heat stablePhotoinitiator 369, High-Temperature
Thermally stabilised BDMB with decomposition temperature raised by 50°C. Maintains initiation activity in cure ovens and engine-bay coatings.
High solubilityPhotoinitiator 369, High-Solubility
Solvate-modified BDMB with 30% higher solubility in oligomers and reactive diluents. Drops cleanly into high-solids and solvent-free systems.
Water-basedPhotoinitiator 369, Water Dispersion
Stable 40% aqueous dispersion (≤100 nm) of BDMB with non-ionic surfactant. Drop-in for water-based UV coatings, eliminating solvent VOC.
BlendPhotoinitiator 369 Blend (369 + EDB)
BDMB + ethyl 4-(dimethylamino)benzoate amine synergist (4:1). EDB boosts dark / pigmented system cure speed by 30–50%.
