PL -200
by Esstech
Hydrophilic fumed silica. Acts as a photoinitiators as well as rheology modifier. Provides excellent gloss and very good anti-settling properties in pigmented systems. Offers better anti caking control. Used in UV, solvent-based and water-based systems. Also used in adhesives gel coats. Recommended usage level ranges from 0.5-20.00%.
SpeedCure 84
by Lambson (Sartomer)
SpeedCure 84 by Lambson (Sartomer) is a 2-hydroxy-2-methyl-1-phenylpropanone. Acts as a highly efficient, widely used, Type I photoinitiator. Exhibits good reactivity & low yellowing and provides good surface cure. Radicals are formed by a cleavage mechanism and as such does not require an amine synergist to promote radical production. The radicals formed can rapidly initiate the photo-polymerization of suitable acrylate oligomers and other monomer formulations. It is a clear colorless to yellowish liquid. SpeedCure 84 is used in adhesives. Suggested levels of use are 0.5 – 5% w/w.
SpeedCure BKL
by Lambson (Sartomer)
SpeedCure BKL by Lambson (Sartomer) 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 a 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 is used in adhesives. Suggested levels of use are 0.5 – 5% w/w SpeedCure BKL (quantities vary depending on individual formulations and applications).
SpeedCure MBF
by Lambson (Sartomer)
SpeedCure MBF by Lambson (Sartomer) is a methylbenzoylformate. Acts as a highly efficient photoinitiator. Exhibits low odor and low oxygen inhibition. Offers excellent surface cure response, increased crosslinking density and non-yellowing properties. It is easy to handle and is used in conjunction with Speedcure TPO or Speedcure BKL. SpeedCure MBF is recommended for use in adhesives. Recommended levels of use are 3 – 5% w/w in clear coatings.
