The peaks from 800 – 450 cm-1 are probably pigment bands, and identify titanium dioxide.
Wilko Emulsion Vinyl Matt White

The peaks from 800 – 450 cm-1 are probably pigment bands, and are distinctive of titanium dioxide.
Homebase Non-Drip Gloss Pure White
As you can see from the spectrum the broad peaks around 3500, 1500 and 1200 cm-1 and the sharp peaks at around 2900 and 1800 cm-1 are polymer bands and are characteristic of polyurethane resin. The peaks from 800 – 450 cm-1 are probably pigment bands, and identify the bands of titanium dioxide.
Comparisons:
Same Manufacturer but different paint types.
When comparing paints of the same make it is possible to see that they have regular peaks around the same wave numbers but the difference being the different intensities.
Homebase –
- Quick drying primer
- Matt Vinyl Emulsion
- Silk Vinyl Emulsion
- Non-Drip Gloss Pure White
As you can see from the homebase paints, all of them have very similar characteristics and all have been identified s containing the same pigment and polymer. All of these paints contain bands which identify a polyurethane resin and titanium dioxide.
Dulux
Again both the dulux paints show similarities and both have bands which are characteristic of polymers around the same wave numbers. Both paints contain identifications of a polyurethane resin.
Different manufacturer but the same type of paint.
It can be seen in the spectra that bands appear around the same wavenumber for similar type paints with an alteration of intensity. This is not as distinct due to the paints containing slightly different alterations.
Vinyl
- Homebase Silk
- Wilko
- Dulux
- Homebase Matt
All the vinyl paints, as you can see from their spectra have bands characteristic of a polyurethane resin. There is a slight difference for homebase silk emulsion as it has no distinct pigment bands.
Matt
- Wilko
- Dulux Vinyl
- Homebase Vinyl
- B&Q
- Glixtone
All of the matt paints have the same type of bands identifying a resin at the higher end of the spectrum between 3500 – 2900 cm-1.
Wilko emulsion, dulux vinyl and homebase vinyl all have bands around the same wave numbers and those identify binder bands and are characteristic of a polyurethane resin. They also have pigment bands identifying titanium dioxide.
The glixtone and B&Q paints are slightly different in the lower end of the spectrum but the peaks are similar to those of the others. Neither of these two paints have distinct pigment bands either. This difference could be due to the fact that the other paints are vinyl paints and so are more than just plain matt.
Gloss
- Homebase Non-Drip
- Hammerite Radiator Enamel
Both paints have the same resin bands in the higher end of the spectrum from 3500 – 2900 cm-1 and have the same pigment bands identifying titanium dioxide. But they differ quite a lot in the middle. This difference could be due to the different manufacturers and also the hammerite is an enamel paint and also high gloss, whereas the homebase is non-drip and not a high gloss.
Unknowns:
No. 4
This unknown shows pigment bands from 800 – 400 cm-1 which is characteristic of titanium dioxide and also has binder bands which identify an alkyd resin. The paint spectrum that also has these characteristics is that of Hammerite radiator enamel.
When looking at the spectra together you can see obvious similarities of the position of the peaks and also the intensity. Both spectra have the same shape and size bands in very similar positions.
