Aluminum compounds as additional crosslinkers for air-drying high-solids alkyd paints

Accelerated UV ageing studies of acrylic, alkyd, and polyvinyl acetate paints: Influence of inorganic pigments

“…The absorption variation of the CH 3 Furthermore, after UV exposure of the alkyd binder it was noticed that the peak at 974 cm -1 of the out of plane =CH bending of trans-structures gradually became a shoulder (Fig. 3c), mostly due to the oxidation of the double bonds [27,28] or possibly through Norrish type I and II reactions [27]. …”

Effect of Additives on Weathering

“…] ingly brittle. 205 These two examples show that the nature of crosslinking influence on mechanical properties is of importance rather than the simple number of crosslinks.…”

Synthesis and evaluation of tetra(2,7-octadienyl) titanate as a reactive diluent for air-drying alkyd paints

“…[13][14][15][16][17] The crosslinking mechanism involves hydrogen abstraction from allylic methylene groups by oxygen in the presence of metal catalysts, yielding a resonance-stabilized radical which further reacts with oxygen to form a hydroperoxide. [18][19][20][21][22][23][24] The resulting hydroperoxide is degraded by metal catalysts into radicals and reacts with the double bonds in the resin to produce chemical crosslinking. 7 For this reason, a suitable reactive diluent for air-drying alkyd paints should possess an allylic methylene group as a reactive site for efficient oxidative curing.…”
