Benzil ketones, a class of organic compounds, play a pivotal role in the realm of UV curing as effective photoinitiators. Among them, BDK (Benzildimethyl ketal), commonly known as Photoinitiator 651, stands out for its versatile performance across a wide spectrum of UV-curable applications. NINGBO INNO PHARMCHEM CO.,LTD. is proud to offer high-quality BDK photoinitiators, contributing to advancements in coatings, printing inks, adhesives, and more.

What are Benzil Ketone Photoinitiators?

Benzil ketones are characterized by their specific chemical structure, which allows them to efficiently absorb UV light and generate free radicals. This process is fundamental to initiating the polymerization of monomers and oligomers in UV-curable formulations. They are typically Type I photoinitiators, meaning they undergo alpha-cleavage upon UV exposure, directly producing reactive radicals that drive the curing process. This direct cleavage mechanism often translates to high reactivity and fast curing speeds.

Key Advantages of BDK 651 Photoinitiator

Photoinitiator 651 (BDK) is a well-regarded member of the benzil ketone family, prized for several key attributes:

  • Excellent Surface and Through Cure: One of the most significant benefits of BDK 651 is its ability to promote both effective surface cure and adequate through cure. This dual action ensures that the entire depth of the coating or ink layer solidifies properly, leading to robust and durable finished products.
  • High Purity and Reactivity: NINGBO INNO PHARMCHEM CO.,LTD. provides BDK 651 with high purity, which is crucial for consistent and predictable performance. Its inherent reactivity allows for efficient initiation of polymerization, contributing to faster curing times.
  • Versatility: BDK 651 is compatible with a wide range of UV-curable systems, including acrylate and methacrylate-based formulations. This makes it suitable for diverse applications where reliable curing is essential.
  • Good Solubility: Its favorable solubility in common organic solvents and monomers ensures easy incorporation into various formulations without phase separation issues.

These characteristics make BDK 651 an ideal choice when seeking an effective surface and through cure photoinitiator for demanding applications.

Applications Across Industries

The applications for benzil ketone photoinitiators like BDK 651 are vast, reflecting their efficiency and versatility:

  • Coatings: In the coatings industry, BDK 651 is used to cure a variety of finishes, including wood coatings, plastic coatings, and overprint varnishes. It contributes to hard, scratch-resistant surfaces with excellent adhesion.
  • Printing Inks: For printing inks, BDK 651 ensures rapid drying and vibrant color reproduction on various substrates. Its ability to cure both the surface and the ink film beneath is critical for high-quality printing.
  • Adhesives: UV-curable adhesives benefit from the fast curing and strong bonding provided by BDK 651, making it valuable in electronics assembly, medical device manufacturing, and other precision bonding applications.
  • 3D Printing: In stereolithography (SLA) and digital light processing (DLP) 3D printing, BDK 651 acts as a key polymerization initiator for UV applications, enabling the layer-by-layer creation of complex geometries.
