QS-52 environment-friendly water-based rust inhibitor

Function and scope of
For passivation anti-rust black metal (castings, forgings, sheet metal, etc.) are widely used in machinery manufacturing, petroleum, chemical industry, transportation, metallurgy, electric power, textile printing and dyeing industry, publishing and printing industry as well as military, mining power plants, ships, industrial, medical, machinery and other industries.
Product Features
Strong ability of anti-rust, no smell, no gas volatilization, do not pollute the operating environment
Does not contain fats and oils composition, after drying, the surface non-greasy, easy to use 
All ingredients meet the biodegradability requirements not phosphorus 
Use
1：prior to use, the surface oil, rust and other foreign matter.
2：With water before use the preparation of the working fluid, and mixing evenly, the dilution ratio can refer to the table and determined through experiments.
Dilution ratio and anti-corrosion effect:
The working fluid concentrations of rust-proof time (casting)
2 ~ 5% wt of 3 to 7 days (working)
10 ~ 15% wt 3 to six months
20% wt and 12 months
Description: The above data are for reference only, not as a quality assurance or acceptance basis.
(b) anti-corrosion effect by the workpiece material, surface condition, climate, air pollution, as well as dilution water quality, construction method, the workpiece stacking and other factors, it is recommended that before the official use of small volume samples, select the appropriate concentrationand construction methods, the lowest cost to obtain a satisfactory anti-corrosion effect.
c jobs after passivation and dry sealed and stored extend the anti-rust of time.
Can be used to soak, brush or spray (shower), the way construction, brush or spray require parts of the surface to dry and be careful not to leak Tu. Recommendations for cracks, blind holes and other difficult painted to take corresponding measures.
4 workpiece coated with a passivating agent to try to avoid direct contact or by other stains by hand, so as not to affect the anti-corrosion effect. If conditions permit, to extend the anti-rust of parts packaging.
