High Quality Irgacure 651 (CAS 24650 - 42 - 8) is a highly efficient photo - initiator with excellent performance. It has a unique chemical structure that allows it to quickly initiate the polymerization reaction under ultraviolet (UV) light. The product is characterized by its high purity and consistent quality, ensuring reliable performance in various applications. The melting point of Irgacure 651 is typically in the range of 65 - 75 °C, and it has good solubility in common organic solvents such as acetone, toluene, and ethyl acetate. Its molecular formula is C₁₆H₁₆O₃, and the molecular weight is approximately 256.29 g/mol.
Irgacure 651 is widely used in the UV - curing industry. It is commonly employed in coating applications, such as wood coatings, metal coatings, and plastic coatings. In wood coatings, it helps to achieve a fast - drying and hard - wearing finish, enhancing the appearance and durability of the wood surface. For metal coatings, it provides corrosion resistance and a smooth, glossy finish. In plastic coatings, it can improve the scratch resistance and chemical resistance of plastic products.
It is also used in the printing ink industry. UV - curable inks containing Irgacure 651 can be cured rapidly under UV light, which is suitable for high - speed printing processes. This results in sharp, clear prints with excellent color fidelity and abrasion resistance. Additionally, it is used in the adhesives and sealants industry, where it enables fast bonding and sealing, providing strong and reliable joints.
When using High Quality Irgacure 651, it is important to follow the proper procedures. First, it should be thoroughly mixed with the resin or other components in the formulation. The recommended dosage usually ranges from 1% - 5% by weight, depending on the specific application and the desired curing speed. The mixture should be stirred well to ensure uniform dispersion of the photo - initiator.
After the formulation is prepared, it can be applied to the substrate using appropriate coating or printing methods. Once applied, the coated or printed substrate should be exposed to UV light. The intensity and duration of UV exposure depend on the thickness of the coating or ink layer, as well as the specific curing requirements. Generally, a UV lamp with a wavelength of around 365 nm is commonly used for curing Irgacure 651 - containing formulations.
Case 1: Wood Furniture Coating
A furniture manufacturer was looking for a high - performance coating solution to improve the quality and production efficiency of their wood furniture. They used a UV - curable coating formulation containing High Quality Irgacure 651. After application and UV curing, the furniture had a smooth, hard, and glossy finish. The curing time was significantly reduced compared to traditional solvent - based coatings, from several hours to just a few minutes. This not only increased the production throughput but also reduced the energy consumption and environmental impact. The coated furniture also showed excellent scratch resistance and chemical resistance, which improved the overall durability of the products.
Case 2: High - Speed Printing
A printing company was facing challenges in meeting the high - speed printing requirements of their clients. They switched to a UV - curable ink formulation with Irgacure 651. The new ink could be cured instantly under UV light, allowing for high - speed printing at speeds of up to 300 meters per minute. The printed materials had sharp images and vivid colors, with no smudging or bleeding. The abrasion resistance of the prints was also improved, ensuring that the printed materials could withstand handling and transportation.
