Water-based rust inhibitor

Maxtop Water-based rust inhibitor (MTWBRI) is an environmentally friendly water-based rust preventive liquid compounded from multiple surfactants and rust inhibitors. It appears as a colorless to light yellow liquid. Cost-effectiveness, it can replace oil-based rust inhibitors and reduce treatment costs by more than 30%. Convenient to use, infinitely water-soluble, supports immersion, spraying and brushing. No cleaning required. The film is transparent and leaves no residue. Adapt to high humidity and salt spray environments.

How to use

（1）Preparation: Before using water-based rust inhibitor, you need to make sure the workpiece surface is clean and free of oil. If there is oil or rust on the workpiece surface, you need to remove oil and rust first. You can use a metal pretreatment "two-in-one" product or clean it by mechanical methods such as shot blasting and sand blasting.
（2）Dilution ratio: The dilution ratio of water-based rust inhibitors varies depending on the specific product and usage scenario. The generally recommended concentration is 5% -8% , but the concentration can be appropriately increased during high-pressure spraying and ultrasonic cleaning.
（3）Immersion method: Immerse the workpiece in a diluted water-based rust inhibitor for 2-4 minutes. After soaking, the workpiece needs to dry naturally.
（4）Spraying method: Use a spray gun to evenly spray the diluted water-based rust inhibitor on the surface of the workpiece.
（5）Ultrasonic cleaning: Use an ultrasonic cleaner at temperatures above 60°C for better cleaning results .
