Abstract. The present paper describes the assessment of colour
parameters
of industrial produced paints for horizontal signalization (designed as
POM S1 and POM S2 / ZEB 1 and ZEB 2) of white colour hue, coming from
two
different producers ("Pomoravlje" and "Zorka") with reference to an
independent
sample (IND 0) and some physical features of each sample. Colorimetric
characterization of samples was performed by the reflectance
spectrophotometer
"Update Colour Eye 3000". Standard and modified test methods (ASTM)
were
performed to establish physical features of the paints. The industrial
produced paints show better values of the investigated parameters and
features
and satisfy standards prescribed by law. POM S2 sample with dry film
thickness,
similar to the same of other samples, provides the best physical
features
maximizing quality and minimizing protection cost.
Key words: colour
parameters,
marking paints, physical features, reflectance spectrophotometric
method,
whiteness index.
PARAMETRI BOJE, INDEKSI BELINE I
FIZIČKA
SVOJSTVA ORGANSKIH
PREMAZA ZA HORIZONTALNU SIGNALIZACIJU
Ovaj rad opisuje određivanje parametara boje industrijski proizvedenih
organskih premaza za horizontalnu signalizaciju (označenih kao POM S1 i
POM S2 / ZEB 1 i ZEB 2), belog tona boje, dva različita proizvođača
("Pomoravlje"
i "Zorka") u odnosu na nezavisni uzorak (IND 0) i neka fizička svojstva
svakog pojedinačnog uzorka. Kolorimetrijska karakterizacija uzoraka je
izvršena refleksionim spektrofotometrom tipa "Update Colour Eye 3000".
Standardne i modifikovane test metode su korišćene radi utvrđivanja
fizičkih
svojstava organskih premaza. Industrijski proizvedeni premazi pokazuju
bolje vrednosti ispitivanih parametara i svojstava i zadovoljavaju
standarde
propisane zakonom. POM S2 uzorak sa debljinom suvog filma, sličnom
istoj
ostalih uzoraka, obezbeđuje najbolja fizička svojstva povećavajući
kvalitet
do maksimuma i snižavajući cenu zaštite do minimuma.
