SpeedCure BKL

Technical Datasheet | Supplied by Lambson
HSP Distance with Chiguard® 5411: 1.2
SpeedCure BKL by Lambson is a 2,2-dimethoxy-1,2-phenylacetophenone. Acts as a highly efficient, widely used, general purpose, Type I photoinitiator. The radicals formed by an α cleavage mechanism rapidly initiate the photo-polymerization of suitable resin formulations. Exhibits fast cleavage reaction, high thermal stability and longer shelf life. It does not require presence of an amine synergist. Highly compatible with most pre-polymers, resins and monomers used in UV curing industry. It is soluble in most organic solvents. Prevents quenching of the excited state by oxygen and selected monomers. SpeedCure BKL by Lambson is used in adhesives. Suggested levels of use are 0.5 – 5% w/w Speedcure BKL (quantities vary depending on individual formulations and applications).

Hansen Solubility Parameters

[18.6, 3.6, 5.2]
[δD - Dispersion force interactions, δP - Polar force interactions, δH - Hydrogen bond force interactions]

Please note, these HSP values are estimations. It is based upon the “like seeks like” principle. It splits an ingredients interactions into three parameters; δD (Dispersion force interactions), δP (Polar forces interactions) and δH (Hydrogen bond force interactions). Hansen Solubility Parameters can help you find a wide range of products that are predicted to be compatible with SpeedCure BKL. A practical determination of these HSP values would provide higher certainty. Learn More.
