Supply 817-5 water-based sealing agent and anti salt spray agent

  817-5# aqueous sealant
Introduction: 817-5# water-based sealer is a kind of brown liquid
It is specially used for copper plating, brass and red copper
Copper plating and electroplating are not easy to burn
It can form a dense protective film on the surface of metal (the effect of workpiece after electroplating is better)
It has strong anti rust, anti-corrosion and anti discoloration functions
It is easy to use and operate
The required equipment is simple
It can also be used for metal stamping iron parts, Various standard parts after plating (such as nickel, chemical nickel, blackening, black nickel, tin, zinc, chromium, etc
) are treated with rust and corrosion prevention, which can be used in electroplating, continuous electroplating and chemical plating
The antirust ability and salt spray resistance of the treated workpiece can be greatly strengthened, and the surface gloss is good
It will not stick together and affect the conductivity and welding

Operation flow: 1 electroplating workpiece → 2 two washes → 3 passivation → 4 two washes → 5
817-5# water based sealer & rarr; 6 drying (drying directly without washing water until the white liquid just disappears
Too long drying time will affect the appearance and salt spray resistance) → packing
Operation process:
Concentration: 2-20% (i
e
2-20 liters of 817-5# sealant in 100 liters of working fluid, 80-90 liters of pure water, standard value: 10%)
Working fluid temperature: please dilute with normal temperature water
If it does not dissolve, please dilute with 25-35 ℃ warm water

Time: 30 seconds - 5 minutes (if time permits, it is recommended to soak for more than 3 minutes)
Drying temperature: 80-100 ℃ (the soaked workpiece can be directly dried without washing
If it affects the appearance, it can be slightly washed and then dried)
Concentration usage parameters:
 

thick , degree	workpiece surface state after treatment	salt fog (neutral) resistance
5% (it is recommended to dilute with pure water)	dryness	no rust in 18-28 hours
10% (it is recommended to dilute with pure water)	almost no oil feeling	no rust in 24-50 hours
20% (it is recommended to dilute with pure water)	slight oil feeling	no rust in 50-124 5 hours
1 Shake the 817-5# sealing agent stock solution evenly before use, and then pour it out of the cylinder The temperature of diluted water is 20-30 ℃, 2 The working fluid that has not been used for a long time shall be stirred evenly before operation 3 The above data are only for reference (due to different plating layers, plating types and workpiece materials) 4 Working fluid maintenance is calculated and added according to the brought out volume 5 It is recommended to replace the working fluid after one week of use 6 If there are spots on the surface of the workpiece after treatment, reduce the workpiece and drying temperature to 40-50 ℃, and operate the spotted workpiece again without re electroplating 7 If you have any problems during operation, please call to solve them

 
Note:
1
Sometimes it is light yellow, sometimes it is dark red, sometimes it dissolves faster, sometimes it dissolves slower, and it is normal
Please feel free to use it

2
This product 817-5# sealer is of strong salt spray resistance type
If the anti rust and salt spray resistance is poor, please extend the soaking time or increase the concentration
If the oil feeling is too heavy, please reduce the concentration

3
If the hanger is directly put into this product for treatment, please clean it and then put it into the plating bath, so as not to bring the liquid medicine into the plating bath and affect the plating bath
4
If the test results fail to meet your requirements, please tell us the reason so as to provide a more suitable model

Storage: please put it in a cool and ventilated place, away from high temperature, open fire and inflammables
