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.
Ultra purePhotoinitiator 369, Electronic Grade (Ultra Pure)
Ultra-pure 369 with metal-ion content ≤10 ppb. For semiconductor packaging, fine-line PCB and LCD photoresist formulations.
BlendPhotoinitiator 369 Blend (369 + EDB)
BDMB + ethyl 4-(dimethylamino)benzoate amine synergist (4:1). EDB boosts dark / pigmented system cure speed by 30–50%.
