Photo-latent titanium catalysts

A titanium-oxo-chelate catalyst formulation, comprising: (i) at least one compound of the formula (I), wherein R, R, R, R, R, R, R, R, R, R, Rand Rindependently of each other are for example hydrogen, halogen, C-Calkyl, C-Caryl which is unsubstituted or substituted; or R, Rand Rand/or R, Rand Rand/or R, Rand Rand/or R, Rand Rtogether with the C-atom to which they are attached each form a C-Caryl group which is unsubstituted or substituted; or Rand Rand/or Rand Rand/or Rand Rand/or Rand Rtogether with the C-atom to which they are attached form a 5- to 7-membered carbocyclic ring; at least one chelate ligand compound of the formula (IIa), (IIb) or (IIc), wherein R, R, R, R, Rand Rare defined as above for formula (I), is suitable as photolatent catalyst formulation for polymerizing compounds, which are capable to crosslink in the presence of a Lewis acid. 

Photo-latent titanium-oxo-chelate catalysts

Described is a method and an apparatus for producing cured coating films on a substrate surface. Specifically, a portable spraygun may be used to initiate radiation cure without the operative having to be protected from radiation. The spraygun comprises a supply channel for a radiation-curable coating composition, a needle, a reserve for the radiation-curable coating composition, and, optionally, a supply channel for a gas.

Spraygun for producing cured coating films and methods of use thereof

The present invention provides photolatent Ti-chelate catalyst compounds of formula (I), wherein Ris for example C-Caryl which is substituted by one or more R', R&#x2032;or R&#x2032;; or the two Rtogether are unsubstituted linear or branched C-Calkylene; R, R, R, R&#x2032;, R&#x2032;, and R&#x2032;independently of each other are for example hydrogen, halogen or linear or branched C-Calkyl; R, Rand Rindependently of each other are hydrogen, linear or branched C-Calkyl, C-Caryl, Br or Cl, provided that not more than one of R, Rand Ris hydrogen; as well as formulations comprising said compounds and defined 1,3-diketones. 

Photo-latent titanium-chelate catalysts

The present invention provides organometallic latent catalyst compounds, which are suitable as catalysts in polyaddition or polycondensation reactions which are catalysed by a Lewis acid type catalyst, in particular for the crosslinking of a blocked or unblocked isocyanate or isothiocyanate component with a polyol or polythiolto form a polyurethane (PU).
