Benzoyl isopropanol

Benzoyl isopropanol (CAS 7473-98-5), commercially recognized as HMPP and 2-Hydroxy-2-methylpropiophenone, is a photoinitiator that triggers free-radical polymerization upon UV exposure. It is used across coatings, adhesives, and printing to enable rapid, solvent-free cure cycles. In UV-curable coatings and industrial varnishes, HMPP initiates crosslinking under UV light.

This enables high-throughput production lines with minimal thermal input. Printing ink formulators rely on it for fast-cure flexographic and screen-printing systems where sharp cure response is critical. Low yellowing properties are essential for these applications. In adhesive and sealant formulations, it supports UV-cure processes for optical, electronics, and label applications.

Bond integrity and cure speed are production priorities in these sectors. Personal care formulators also incorporate it into UV-curable nail gel systems for performance. Controlled cure depth and compatibility with acrylate monomers determine its effectiveness. Benzoyl isopropanol is supplied as a clear to pale yellow liquid for industrial use.

It is available in technical and photoinitiator-grade specifications suited to industrial coating, ink, and adhesive applications. Packaging typically ranges from drum quantities to IBC. Bulk procurement options are standard, with smaller quantities available for formulation development. This material meets rigorous industrial standards for consistency and reactivity.
