DAYLIGHT FLUORESCENT PIGMENTS

DAYLIGHT FLUORESCENT PIGMENTS are used for their brilliant, eye catching shades. Chemically these are solid solutions of one or more dyes in a transparent high-molecular weight synthetic resin and are offered as very brightly colored free flowing powders.

FLUORESCENCE Conventional Pigments produce color by selectively reflecting part of the incident light, absorbing the remainder, which is covered to heat. Fluorescent pigments, however, convert part of this absorbed energy into light of their own color, thus re-emitting more light than actually falls on them causing a glow called Fluorescence.

LIGHT FASTNESS of fluorescent pigments on indoor exposure is usually unlimited, while on outdoor exposure these tend to fade gradually.

HEAT RESISTANCE varies from one series to another as also from one application to another. Cato PL Series offer heat resistance up to about 260 ° C and are specially designed for plastics.

SOLVENT RESISTANCE must be checked for specific solvent / combinations for the recommended grade of pigments. Care must be taken that the temperature while dispersing the pigment in the medium remains below 50 ° C.

DISPERSABILITY of these pigments is exceptionally good and stirring or soft grinding in the suitable binder / media is enough.

TRANSPARENCY of these pigments being exceptional, it is recommended to use these on white ground. Blending with other shades / opacifiers should be avoided.

CATO DAYLIGHT FLUORESCENTS : Following new grades / products have been developed in respect of our regular range of Fluorescent Pigments.

6000 Series: Chemically these are solid solutions of Fluorescent dyes in amino-formaldehyde sulphonamide resin. 6000 series are brilliant quality, high strength pigments, high softening points & solvent resistance. Thus these are used in solvent based, oil and water based applications as well as in plastics, offering very good dispersion, heat resistance, strength etc.

PL Series : Thermoplastic, formaldehyde free, high strength colors, with improved heat resistance, which melt blend in plastics. Thus these are Fluorescent Pigments specially made for Plastics application (except P.V.C. Calendering).

CATO 6000 SERIES DAYLIGHT FLUORESCENT PIGMENTS

Cato 6000 series are solid solutions of fluorescent dyes in amino –formaldehyde sulphonamide resin. These are thermoplastic type brilliant quality, high strength pigments, with high softening points & solvent resistance. Thus these are used in solvent based, oil and water based application as well as in plastics, offering very good dispersion, heat resistance, strength etc.
Physical Properties
Appearance : Fine Powder
Decomposition Point Temperature : 195 ° C to 200 ° C
Softening Point : 120 ° C to 130 ° C
Average Particle Size : (a) 3-4 microns
(b) No residue on 400 mesh
I.S. Tert Sieve
Bulk Density : 0.55 to 0.65 gms/cc
Free Formaldehyde : Below detectable limit
Refractive Index : 1.6
Specific Gravity : 1.3 to 1.4
Dispersibility : Due to micro fine particle size Cato Fluorescent
Pigments can be easily dispersion equipment.
Oil Absorption : 50 to 60 gms. Of oil per 100 gms. of pigment.

Solvent Resistance: 6000 series possess good resistance to Ketone, Ester and Alcoholic solvents , Aromatic aliphatic etc.

Formulating with 6000 series:

6000 series Daylight fluorescent pigments should be used for their eye catching, bright shades, these color disperse easily in suitable vehicle on stirring or very limited soft grinding excess shear / grinding is not recommended and the temperature while dispersion should be below 50 ° C. a high loading of pigments is required to achieve good strength, as fluorescents are generally weaker than most other conventional pigments. Addition to Opacifiers / Toners / Organic pigments should be minimal as these tend to lead to loss of brightness / light fastness.
