I'm looking for an orange pigment for an aerosol formulation. Binder :
acrylic. Solvent : ketonics and acetates. Propellant : diethyl ether.
We tried, first, a monoazoic orange 5 that didn't go well in such polar
solvents. After a month @ 50°C, it became dark brown.
We've got a pyrazolone orange 13 that behaves better in solvents, but has
low UV resistance.
We also have a benzimidazolone but the price is so huge that we didn't even
My questions are twofold :
1 - Does anyone know where I can find a list of the chemical nature of
pigment related with their colour index ?
2 - Does someone think of a particular orange pigment, with a strong shade,
near the red, so that we can formulate it to get a RAL 2009 ? ... at a price
lower than 20-30?/kg ?
Thank you in advance.
