Zinc Flake CoatingTechnical Data Sheet

 

1 Zinc Flake Coating Information

Trade Name: Zincover

Article/Model No.:JH-9310

 

2 Composition/information on ingredients

JH-9310 is made up of three packs: A,B and C;

Pack A: It is silver gray slurry that mainly chemically combined with super fine flake Zn, super fine flake Al and organic additive.

Pack B: It is water solution that mainly combined with corrosion protecion additive, particular regulator water solution etc.

Pack C: It is the tackifier of the coating which mainly made up of cellulose white or yellowish powder.

3 Performance Charcteristic

Chrome free , film is silver grey to silver white, better corrosion protection performance.

4 Coating Process

4.1 Mix Ratio

Pack A: Pack B: Pack C=1:1: X(according to different viscosity demand )

4.2

Before Mixture, Keep weighted A&B into the water bath at 25±2℃ , then stir A to make metal slurry disperse uniformly by frequency mixer ,after A is fully evenly dispersed, reduce the agitating speed to 60r/min, and add B.

4.3

Add B to the stirring A slowly.

4.4

Stir the mixture about 1~2 hours after B added, then add C. C should be powdered if lump exist.(The barrel temperature should not be lower than 20℃, otherwise C will not be dissolved sufficiently .)Then stir 12 hours alowly and continuously.

4.5

The coating should be filtrated by 80-100 mesh stainless steel screen before pouring into dip barrel.

v

4.6

Temperature control device should be equipped with dip barrel to keep the temperature of coating at 22±2℃.(If temp. is too high, the paint is liable to deteriorate, and viscosity will be effected.) The coating should be stirred circularly to keep evenly dispersed.

4.7

Test Specific gravity,PH,Temperature,Viscosity of coating every 8 hours if operate continuously.

5 Technical data

 

No. Item Data
1 PH (20℃) 5.0-8.0
2 Specific gravity (20℃) 1.30-1.40 (spray coating)
3 Viscosity According to operating demand.
4 Operating temperature 22±2℃

 

6.1 Degreasing

The workpiece should be degreased if there is oil on the surface. There are three processing methods:

1.High temperature

2.Neutral water-base degreasing agent

3.Organic solvent such as methylene chloride.

 

6.2 Derusting

The workpiece can not be coated if there is rust or burr on the surface.The best processing method is shot blasting. The corrosion resistance of coating will be effected if acid cleaning adopted.

 

6.3 Coating

The workpiece afer degreasing and shot blasting should be coated through Dip-Spin coating or Spraying Coating.

 

6.4 Pre-heating

The workpiece after coated should be Pre-heated as soon as possible at 80~150℃ for 8~15 mins to evaporate. ( according to heat absorption of workpiece.)

 

6.5 Curing

The workpiece after pre-heating should be cured at 300-340℃ for 15~30 mins. ( according to heat absorption of workpiece.)

 

7 Attentions

Other chemicals such as any kinds of acid, alkali salt can not be mixed into coating, for these can activate Zn & Al plate to aging the coating.

Avoid irradiation of sunshine and ultraviolet ray for long time when operating, otherwise it will accelerate aging or polymerization of the coating .

It is very important to control the temperature of coating. If the temperature of coating changes when operating, it will effect the viscosity, then effec the coating quatity on workpiece. So the relations among temperature,viscosity and spinning process shoud be controlled well when coating.

The viscosity will be different if coating method is different. Choose low data if spray coating,and choose high data if dip spin coating.

 

8 Packing

Pack A: 16kg/ Metal Barrel Pack B: 50kg/200kg/1000kg Plastic Barrel Pack C: metal barrel

 

9 Quality guarantee period

Before compound 6 months at 5~ 20℃

After compound 30 days at 5~20℃

Try to avoid transportation in hot seasons or stored in container with high temperature for a long time. And delivery the coating as soon as possible. The best transport temperature should control under 30℃.
