Optical Brightener KCB is bright yellow powder with melting point 212â??, it is insoluble in water and the maximum absorption wave length is 370nm. It has very high stability and very excellent weather resistance and migration resistance, so it is very popular and very widely used in Plastic, Coating, Painting, Ink, Copolymer, Synthetic fiber, Polyester fiber etc. Optical Brightener KCB Pure Powder 98.5%min with CAS No. 5089-22-5.
Optical brightener FP-127 is a heat-resistant, solvent-soluble, chemically stable optical brightener that provides better color. It is used to offset the yellow color of the polymer and produce a whiter appearance. Optical brighteners change the wavelength of light by absorbing ultraviolet light, and then emit light in the form of fluorescence. It can also be used as a tracer in various applications and as an optical brightener in thermoplastics, coatings, printing inks, dyes, man-made fibers, waxes, fats and oils. This fine powder form is very suitable for: 1.) Reducing the clogging of the equipment is essential to increase productivity and 2.) It is essential for the application efficiency of the clear coating to disperse and smooth the appearance of the coating. Optical Brightener FP-127 Pure Powder 99%min with CAS No. 40470-68-6.
Bright red and light blue. It is soluble in cold water, soluble in hot water and ethanol for blue. It is yellow-brown in concentrated, and after dilution becomes green, then it becomes yellow-brown. The dye aqueous solution is added with sodium hydroxide to have purple-brown precipitation.
Solvent Violet 13 is a blue-violet oil solvent dye. Good color fastness, good heat resistance, good migration resistance and bright color. Solvent Violet 13 is mainly used for the coloring of polystyrene, ABS, hard polystyrene and various resins. It is also used for the coloring of polyester and fiber protoplasm. Brilliant blue purple. Purple powder. Insoluble in water, soluble in organic solvents such as benzene, xylene, and N, Nâ??Dimethylformamide. In concentrated sulfuric acid for SAP green, dilution after olive, and then a red light blue precipitation. It is mainly used for coloring various resins such as polystyrene, ABS resin, and polyvinyl chloride, and also for coloring polyester protoplasm.
Phthalocyanine blue is also known as Copper Phthaloc yanine blue; Monstral Fast blue; Winsor Blue; Bocour blue; Talens Rembrandt Blue; Thalo Blue; Heliogen Blue.Phthalocyanine blue is a permanent pigment which is unaffected by light, heat, and chemicals. It is used as a colorant in inks, enamels, plastics, paints, chalks, leather, pencils, and photographs. In industry, phthalocyanine blue has replaced all other blue pigments for use in coatings because it is lightfast as well as resistant to chemicals and clumping.
Pigment Violet 23 is a transparent purple pigment with high saturation and high tinting strength. C.I. Pigment Violet 23 has better tinting strength in soft PVC, but poor migration resistance. P.V.23 heat resistance above 230 in polyolefins. When used in transparent polystyrene, the temperature should be lower than 220�°c, above which PV 23 should decompose. When processed in polyester, the temperature is 280â??, stable within 5 hours, and the concentration is above 0.05%. Blue light purple. Light purple powder. Bright color. High tinting strength, high temperature resistance, penetration resistance, and excellent light fastness. It is mainly used for coloring coatings, inks, rubber and plastics, and also for coloring protoplasm of synthetic fibers. Used as high-grade paint (primer for automobile), water-based ink, suitable for in addition to all kinds of plastic, the PA with phthalocyanine blue for plastic formed in the red light blue.
Ultramarine is a blue pigment composed of sodium aluminosilicate and three sulfur atoms in the form of sulfide or sulfate, the unpaired S3-anion originating from the blue. It is prepared from inexpensive modifier components such as kaolin, sodium carbonate and sulfur. Synthetic ultramarine does not show vivid blue as much as natural ultramarine, due to even particle size, diffusing light more uniformly. Synthetic dark blue can be affected by light, oil or lime. Ultramarine has heat and alkali resistant properties. It is used as a colourant and optical brightener for plastics, rubber, inks, paints, cosmetics, detergents, cement, textiles and paper. Ultramarine blue is a saturated, semitransparent, dark, violet-leaning blue. It makes clean violet mixes with cool reds and magentas and is nicely neutralized with siennas or raw umber. Ultramarine's unique property of flocculationâ??the tendency of its particles to clump up togetherâ??give it a lively granulating texture in washes. Interesting effects can be achieved when mixing ultramarine with a micronized pigment, as some of the heavier blue particles will sink a bit while the lightest particles will float above.
Pigment Blue 15:3 is a transparent green shade�²-copper phthalocyanine blue with high heat resistance. C.I.Pigment Blue 15:3 is a single copper phthalocyanine , pure color shade. P.B.15:3 has better heat resistance than copper phthalocyanine, but poorer tinting strength. P.B.15:3 shows good fastness properties and dispersivity. pigment blue 15:3 is a dark blue powder. Its bright color, coloring force is strong. With excellent sun resistance, heat resistance, chemical resistance and permeability resistance. And pigment blue 15:3 is an environmentally friendly pigment.pigment blue 15:3 commonly used in ink, paint and other industrial manufacturing, can also be used for plastic, rubber products and pigment printing paste coloring.
