Solvent Dyes-use

Use:

1.BRIEF INTRODUCTION

Higher plastic colorant are most suitable for various plastic materials coloring, with greater color strength, better fastness to heat, light, acid and alkali. This range is generally used in coloring domestic plastic materials, cop tube materials, fat dyeing, lacquers, inks and master batches dyeing. Some of them are suitable for dyeing chemicals fibre, such as dacron, nylon and cellulose acetate fibre.

2.APPLICATION

Hight plastic colorant are solvent dyes with good solubility and miscibility in organic solvents. This range can be used in the following materials alone as well as mixed in proportion:

• (PS) Polystrene

• (HIPS) High impace polystyrent

• (PC) Polycarbonate

• (UPVC) Rigid poly

• (PMMA) Polymethyl methacrylate

• (SAN) Styrene-acrylonitrile copolymer

• (SB) Styrene-butadiene copolymer

• (AS) Acrylonitrile-stryrene copolymer

• (ABS) Scrylonitrile-butadiene-styrene copolymer

• (372) Styrene methyl acrylic acid copolymer

• (CA) Cellulose acetate

• (CP) Cellulose propylene

3.USAGE

The dye is dissolved in plastic in molecular-distribution. Before molding or preplasticizing, add dyes into plastic materials in proportion and stir thoroughly. The shade can be adjusted in demand. You can obtain transparency color in clear resin, or un-transparency color with titanium pigment. Use

level:

• Transparency color around 0.02%-0.05%

• Un-transparency color around 0.1%

4.SPECIFICATIONS

• Heat fastness:240-300°C

• Light fastness:6-7 or 7-8

• Migration resistance:3-4 or 4-5

• Colorng strength:100%±3

• Moisture:1% max

• Particular size:60 meshes(passed)

Solubility Test:

(1)Dissolve 20gm of Dye in 40ml of solvent stir Thoroughly seal the container Tightly and left over night.

(2)Stir the above Sample weight filter paper accurately before filtering the sample. Then put the residue and filter paper inside A thermostate with 50 temperature Until all the liquid evapavated.

(3)Weight the residue(X) Total weight-weight of filter paper).

• Determine the Solubility by calculation:

• 20 40 X 1000=Solubility (gm/l)

Fastness:

• (1)Light resistance:Used standard Blue Scale as comparsion standard

• (2)Heat Resistance:Automatic Constant Temperature Dryer at 180°C for 10 hours.

• (3)Acid Resistance:immerse in 1% H2SO4 solution for 24 hours.

• (4)Alkali Resislance:Immerse in 1% NaOH Solution for 24 hours.

• (5)Standard symbols for test: A:good B:fair C:Poor
