Description
ADDITOL® MBF is a radical photoinitiator used to facilitate the curing of formulations containing unsaturated materials when exposed to UV light. Here's an overview based on the provided technical datasheet:
Introduction: ADDITOL® MBF functions as a radical photoinitiator that undergoes a photochemical reaction when exposed to UV light, generating radicals that initiate polymerization in systems containing unsaturated groups.
Performance Highlights:
-
- Low viscosity liquid at room temperature.
- Mild odor.
- UV curable products containing ADDITOL® MBF exhibit very good surface cure and limited yellowing.
Suggested Applications: Typically used at levels of 1 - 4% by weight based on the reactive components of the formulation, ADDITOL® MBF finds applications in clear coats for plastic, wood, and metal; overprint varnishes; paper upgrading; and inks and pigmented coatings when combined with other photoinitiators.
Precautions: It's recommended to review the Safety Data Sheet (SDS) for information on identified hazards, recommended personal protective equipment, and procedures before using ADDITOL® MBF.
Storage and Handling: Store the material in a dry area away from direct sunlight, and prevent exposure to UV or visible light. Keep containers closed and protected from physical damage. The recommended storage temperature range can be found in the SDS.
Typical Physical Properties:
-
- Appearance: Clear yellow liquid
- Assay: ≥ 97.5%
- Density at 25°C: 1.16 g/cm³
- Extinction coefficients: 256 nm (68 liters gram-1 cm-1), 344 nm (0.35)
- Viscosity at 25°C: ~5 mPa.s
- Molecular Weight: 164
ADDITOL® MBF facilitates the UV curing process by promoting polymerization, leading to the development of various coatings and inks with desirable properties.
