W4000H is a new type of water-based cleaning agent developed using our patented technology, used to clean stubborn residues such as flux, rosin, oil stains, etc. baked on welding fixtures, fixtures, cyclone separators, and condenser tubes. This product overcomes the industry problem of alkaline cleaning agents being incompatible with sensitive materials such as aluminum alloy fixtures, and has excellent material compatibility with aluminum alloys, synthetic stones, fiberglass materials, etc. Because of its strong cleaning power, good material compatibility, halogen free, low odor, no foam and other advantages, it can be simultaneously applied to multiple cleaning processes such as ultrasonic, spray, immersion and manual brushing, and its service life is 3-10 times that of traditional surfactant-based cleaning agents.
