IV  Construction for reference

◆Surface treatment: wipe off the impurity, for example, floating dust, rust, oil stain, etc. to keep the surface clean and dry;

◆Form of construction work: dip coating;

◆Dilution ratio: add water by 20%~30% of the paint weight (add by 20% as the lower limit for testing, and continue adding if required);

◆Applicable viscosity: dip coating, 20~22s (paint-4cup, 23±2°C);

◆Type of drying: bake at a constant temperature of 210±2°C for 150~180 s;

 

 

V  Controlling bath solution parameters

 

Item	Test method	Indicator	Frequency
Viscosity (s)	Paint-4cup (normal temperature)	20-22 s	Once/2 h
PH value	PH meter/accurate PH test paper	8.2-8.5	Once/day

 

VI  Adjusting solution parameters

◆Viscosity: For low viscosity, add original paint. Extract partial solution before adding the paint if necessary;

For high viscosity, add deionized water while the solid content should be greater than 18.5%;

For excessive viscosity, if the construction requirement can not be met after the upper dilution limit of deionized water has been applied, notify the manufacturer.

 

VII  Attentions

1. Difference in the level of processing metal substrate is referred to final effect and barrier property of the film coating.

2. Stir the original paint evenly before pouring into the bath;

3. Minimize the lowest point area of a work piece when coating, so as to reduce liquid loading;

4. Dip-coating equipment should be fitted with a circulation system that contains a 180 mesh filter. Clean the filter on a regular basis. The system is equipped to keep the solution uniform and prevent settling. Start coating after the bath solution is stirred evenly;

5. Attach a thermostatic apparatus to the circulation system if the solution temperature cannot be controlled as required (Generally speaking, the indoor ambient temperature can not be exceeded). Special note should be taken when the solution temperature is raised due to the entering of exterior heat;

6. Enable the circulation system at least once a week over 30 min if the bath solution is out of service for a long time. Upon completion, spray a thin layer purified or deionized water on the liquid surface to avoid excess settling and skinning (except for solution that are packed into the original packing barrel after operation, be careful not to take in exterior impurity);

7. The bath needs no clean within one year if the solution is maintained normally. However, it should be cleared immediately if any “hard settling” by extracting solution, clearing impurity at the bottom of the bath, and adding the solution back with new paint complemented;

8. Keep the product in a cool and ventilate place (0°C~45°C). The validity is 1 year. If failing to meet the time limit, the product still can be used if proved to be up to standard through inspection. If skinned, remove the skin of paint.
