Methyl Benzoylformate, also known as Photoinitiator MBF with the CAS number 15206-55-0, is a high - quality product supplied by our factory at the best price. It is a white to light - yellow crystalline powder. The molecular formula of Methyl Benzoylformate is C9H8O3, and its molecular weight is approximately 164.16 g/mol. It has a melting point in the range of 47 - 51 °C, and its boiling point is around 260 - 262 °C. This product has good solubility in common organic solvents such as ethanol, ethyl acetate, and toluene, but is sparingly soluble in water.
1. **UV - Curable Coatings**: Methyl Benzoylformate is widely used as a photoinitiator in UV - curable coatings. When exposed to ultraviolet light, it decomposes rapidly to generate free radicals, which initiate the polymerization reaction of monomers and oligomers in the coating. This results in a fast - drying, hard, and durable coating surface. It can be applied to various substrates, including wood, metal, plastic, and glass, providing excellent protection and decoration.
2. **Printing Inks**: In the printing industry, it plays a crucial role in UV - curable inks. It enables high - speed printing processes as the inks can be cured almost instantly under UV light. This leads to sharper images, better color reproduction, and improved print quality. Additionally, UV - curable inks are more environmentally friendly compared to traditional solvent - based inks as they emit fewer volatile organic compounds (VOCs).
3. **Adhesives**: In the production of UV - curable adhesives, Methyl Benzoylformate helps to achieve strong and quick - setting bonds. It is suitable for bonding different materials, such as plastics, rubbers, and metals. These adhesives are used in industries like electronics, automotive, and packaging, where fast assembly and high - strength bonding are required.
1. **Formulation**: When formulating UV - curable systems, the appropriate amount of Methyl Benzoylformate should be added according to the specific requirements of the application. Generally, the dosage ranges from 1% to 5% of the total formulation weight. However, this can vary depending on factors such as the type of monomers and oligomers used, the intensity of the UV light source, and the desired curing speed.
2. **Mixing**: Thoroughly mix Methyl Benzoylformate with other components of the formulation. It is recommended to use a high - speed mixer to ensure uniform dispersion, which is essential for consistent curing throughout the system.
3. **Curing Process**: Expose the formulated product to an appropriate UV light source. The UV light should have a wavelength within the absorption range of Methyl Benzoylformate (usually around 250 - 400 nm). The curing time depends on the thickness of the coating or adhesive, the intensity of the UV light, and the formulation. It is necessary to optimize these parameters to achieve the best curing results.
1. **Wood Coating Application**: A furniture manufacturer was looking for a fast - drying and durable coating solution for their wooden products. They incorporated Methyl Benzoylformate into their UV - curable coating formulation at a dosage of 3%. After applying the coating and curing it under a high - intensity UV lamp for 10 seconds, they observed a hard and scratch - resistant surface. The production efficiency increased significantly as the curing time was reduced from hours (in traditional solvent - based coatings) to seconds. Moreover, the coating had excellent adhesion to the wood, and the finished furniture had a high - gloss appearance that was well - received in the market.
2. **Printing Ink in High - Speed Printing**: A printing company was facing challenges in achieving high - quality prints at high speeds using traditional solvent - based inks. They switched to a UV - curable ink formulation containing Methyl Benzoylformate. In a high - speed web offset printing process, the inks were cured instantly under UV light. This led to sharper images, reduced dot gain, and improved color registration. As a result, the company was able to increase its production volume and reduce waste, improving overall profitability.
