LW-140 die-casting aluminum circulating cleaning additive is a colorless liquid, which does not contain silicate and surfactant. It can be recycled in combination with demulsifying surfactant (cross flow filtration or oil-water separator). It is especially suitable for die-casting aluminum, which is non blackening and non dusting. It can be used in combination with surfactant. It can be used for immersion, ultrasonic and spray cleaning, and can effectively remove grease and pigments.
LW-30 chromium-free passivator for water-free die-casting aluminum is an environmental friendly acid treatment additive. It uses composite metal salts to form a dense and uniform chemical conversion film on the surface of aluminum matrix, effectively improving the adhesion and corrosion resistance of the paint film on the surface of aluminum alloy and the coating. This product does not contain metal chromium and meets the requirements of green environmental protection. It can partially replace the traditional chromium containing passivator for the pretreatment of aluminum alloy surface coating. It can be used in spraying and soaking processes.
