Workers are also more likely to be exposed to triglycidyl isocyanurate
and experience adverse health effects.
used pyromellitic dianhydride (PMDA) in combination with triglycidyl isocyanurate
(TGIC) and 1,4-phenylene-bis-oxazoline (PBOZ) to achieve long chain branched structures.
As a comparison, the [T.sub.g] of some industrial coatings were collected from online and printed literature; [T.sub.g] of an acrylic-melamine coating is 45[degrees]C (21); for a polyester-triglycidyl isocyanurate coating it is 58-69[degrees]C (22); a few thermosetting powder coatings based on triglycidyl isocyanurate
have [T.sub.g] in the range 50-70[degrees]C (23); and a methacrylic copolymer coating has a value of 110[degrees]C (24), etc.
In most cases coating powders and their packaging are not classified as hazardous wastes, but there are possible exceptions, such as coating powders containing triglycidyl isocyanurate
(TGIC) and lead chromate together with the packaging for these powders.
As reported earlier, triglycidyl isocyanurate
(TGIC) was selected as a reactive modifier/additive with high reactivity towards PET even in the absence of additional catalyst(s) (8).
Low molecular weight modifiers for extrusion blow molding or other applications also include [less than] 0.5 wt% triglycidyl isocyanurate
in the presence of catalytically acting amines or salts , and a variety of N,N-diglycidyl substituted benzamide, aniline, diimide or imidazolone compounds .
