Omnirad TPO-L improve surface cure.
Omnirad TPO-L is usually combined with other photoinitiators such as Omnirad 481, Omnirad 73 and Omnirad BP Flake.
Formulated product properties will depend on the actual reactive monomers, oligomers and additives utilized.
Features & Benefits of Omnirad TPO-L:
Omnirad TPO-L is a liquid photoinitiator, making it easy to incorporate into formulations.
Omnirad TPO-L is compatible with most oligomers and monomers used in the UV Radcure industry.
Omnirad TPO-L is also useful for blending with other photoinitiators.
Omnirad TPO-L is suitable for the production of formulations which on curing exhibit low yellowing and low odour.
As Omnirad TPO-L absorbs in the long wave region of the UV spectrum, it is particularly suitable for use in pigmented systems, even those containing TiO2, as well as thick film layers.
Recommended Addition levels of Omnirad TPO:
An addition level of 0.3 - 5% by weight of total formulation is recommended for technical applications.
Storage & Handling of Omnirad TPO:
Storage of Omnirad TPO must be in a cool, shaded, well ventilated and dry area away from direct sources of heat and sunlight.
If crystals found upon exposure to cold temperature, material should be warmed up to approx. 35 - 40 °C to re-melt and stirred until homogenous before use.
Avoid Omnirad TPO contact with alkaline additives and water.
Subject to appropriate storage under the usual storage and temperature conditions, our products are durable for at least 24 months.
Omnirad TPO-L should be handled in accordance with good industrial practice.
