Product name: Photoinitiator TPO
Chemical Name: 2,4,6-TrimethylBenzoylDiphenylphosphineOxide
CAS number: 75980-60-8
Molecular formula: C22H21PO2
Appearance: Light yellow crystalline powder
Purity (C): ≥99.0%
Melting point: 91.0-94.0 ° C (degrees Celsius)
Acid value (mgKOH/g): ≥4
Volatile: ≤0.2%
Ash: ≤0.10%
Uses: TPO is a highly efficient free radical (1) type light, highly efficient Photoinitiator that absorbs over a long wavelength range. Due to its wide absorption range, its effective absorption peak is 350-400nm, and it has been absorbed to about 420nm. Its absorption peak is longer than that of conventional initiators. After irradiation, it can generate two free radicals of benzoyl and phosphoryl groups. It can initiate polymerization, so the light curing speed is fast, it also has photo-bleaching effect, suitable for deep film thickening and yellowing of coating, low volatilization, suitable for water-based. This product is mostly used in white systems, and can be used in UV-curable coatings, printing inks, UV-curable adhesives, optical fiber coatings, photoresists, photopolymer plates, stereolithography resins, composite materials, dental fillers, etc. The use of this product should be based on the results of the actual experiment, the recommended addition amount is 0.5-4% w / w. It is fully cured on white or high titanium white pigmented surfaces. The coating does not yellow, the post-polymerization effect is low, and there is no residue. It can also be used for clear coatings and is especially suitable for products with low odor requirements. Used alone in unsaturated polyesters containing styrene systems, it has high initiation efficiency. For acrylate systems, especially colored systems, it is usually used in combination with amines or acrylamides, and in combination with other Photoinitiators to achieve complete cure of the system, especially for low yellowing, white systems and thick film curing. . Screen printing inks, lithographic inks, flexo inks, wood coatings. Recommended addition amount 0.5-3.0% (colored system), 0.3-2.0% (transparent system)
Packing specification: 20KG packaging
Storage: This product should be sealed and stored in a closed, dry, dark place, avoiding sunlight.
