Solvent and bleed resistant Fluorescent Pigments; Thermoset & Microspherical

UNV-D SERIES

Recommended Applicatoins:

Bleed Resistant Vinyl Plastisols, Specialty Coatings/Inks, Solvent Sensitive Systems, and Crayons

Highlight of Properties:

Thermoset, narrow distributed microspherical particles render properties of good resistance to solvent and bleed, and excellent light scattering and opacity, dispersability, tinting strength, and broad compatibility.

SHADES:

Chartreuse, Green, Orange-Yellow, Orange, Orange-Red, Red, Cerise, Pink, Magenta, Blue, Purple

CHEMICAL NATURE:

A solid solution of fluorescent dyes in an amino resin

PHYSICAL PROPERTIES:

Shape and state:

Solid micron-sized spherical particles

pH:

3.8~ 6 (5% dispersion in water)

*Moisture*:

< 4% (2 gram under 140C for 0.5 hours)

Specific Gravity:

1.3 (20℃)

Solvent Resistance:

Not soluble in most solvent systems. (Solubility is tested in a 40C water bath for 30 minutes. Following the solubility test, appearance of the supernatant is observed and marked for bleed scales.)

Bleed Resistance:

Solvent	Acetone, Methanol, Methyl Ethyl Ketone	Ethanol, 2-Propanol	Ethyl Acetate	Mineral Spirits, Toluene, Xylene
Bleed	2	1	1-2	0

Bleed scales: 0 - negligible; 1 - slight; 2 - moderate; 3 - considerable

*Particle Size* (Microscope):

Maximum 10 um; Average <5 um

Softening Point:

Thermoset; no softening point. But observed color changes at ~260℃

Decomposition Point:

> 300℃; Maximum Processing Temperature: 260℃

*COLOR ASSESSMENT*:

Shade (hue) and strength are compared against an approved standard by trained technicians upon preparing side-by-side drawdowns and placed in standard light box equipped with UV and D65 light source.

STORAGE:

Under conditions that are cool, dry, covered, away from direct sunlight and free of airborne contaminates, UNV-D pigments have an indefinite shelf life.

TOXICITY:

Tests conducted through independent laboratories have found UNV-D-Series Fluorescent Pigments to be "essentially non-toxic." MSDS is available upon request. Good industrial hygiene and handling methods are essential in the use of all products whether or not they are determined to be hazardous.

NOTE:

Items marked with * are standard QC items taken on batch bases.
