the series of products are the professional manufacturing factory a alcohol soluble dyes produced transparent chrome alloy. The production of metal chromium alloy dyes marketing advanced countries around the world, the industry, the aluminum foil coloring and high-grade furniture industry spray on the leather surface enjoys a high evaluation.
this series product "can be resistant to L - Series", Department of 1 : 2 type metal complex dyes. In the chemical molecular structure, containing no dear water-based, so its water resistance, light resistance and permeability of cortex are strong.
main use: use dyeing in natural leather surface spraying. Drum dyeing and the need to have the complementary surface spraying the surface of leather, suede leather surface color and so on. Product characteristics:
the series of products are the liquid dye. Miscibility with water and organic solvent, so as the two-phase type dye. Can be diluted with water to make water paint spray dyeing. Can also be organic solvents such as dyes, ethylene glycol, ethylene glycol monoethyl ether, acetone dilution after the oily surface. The concentration of the dye in the series,
on resin miscibility is phase type. This product can resin, and water based acrylic waterborne polyurethane resin and other use. Nitrocellulose varnish etc. can also be used for oil paints.
using this series of products, all kinds of dry and wet rub resistance, light resistance, water resistance and other resistant properties of leather are improved a lot. And the coating surface luster bright, bright, pores clear soft.
in application, this product can be used for surface spray dyeing, coating or roller coating can also be mixed with pigment paste to use, or do the effect layer coating in the pigment layer. Storage stability
the liquid dye, there will be no dye precipitation under normal circumstances.
this product does not contain the German disable 20 aromatic amines, can be assured use.
the products containing organic solvents were much low toxicity, high boiling point solvent. Physical properties of
the series of products: pH (PH value) according to the various system is slightly different, but all in the 5 8 between (dye: water = 1 : 9 ). Generally, all colors can be mixed use, color, but please do the test before mixing.
this series product is alcohol soluble dye, its miscibility with water has basically restrictions, so when in use, the use of instant solution with water after please, avoid placing too long.
light fastness, dye itself, blue and green, generally is 6 7 class, this test method using carbon arc Cheng, 20 hours exposure, nitrocellulose varnish coating conditions, reach the world level. Packing: 25
application example: (for reference only)
in actual use, according to your company's way of use and requirements, such as luminance color strength, surface, the amine effect etc.. So please test yourself before use, adjust the best formula.
A, direct spray dyeing
can be resistant to liquid dye 150 200
mixed immediately after spraying dye. In actual operation, to about 100 150 ethylene glycol or glycol ether substituted partial diluted with water, then the penetration effect is better.
two, curtain coating
can be resistant to liquid dye 150 200
if you add a little in the formulation (about 10 20 ) the waterborne adhesive, the effect better.
three, and water-based adhesive and use:
waterborne acrylic resin 200 250
can be resistant to liquid dye 50 55
penetrant needed amount
four, and pigment paste and use:
in the pigment paste used in full amount to the United States is resistant to liquid dye to replace the 15% 30% the amount of color strength and transparency enhancement. Spraying
five, oily surface:
can be resistant to liquid dye 50 / acetone or ethylene glycol ether 100
