HH Carbon Steel Degreasing and Rust-Removing Agent

Carbon steel degreasing and derusting agent is a one-step formulation for degreasing and derusting metal surfaces under ambient conditions. It is composed of multiple surfactants, inorganic salts, corrosion inhibitors, and various additives, enabling rapid removal of oil, rust, and oxide scale from workpiece surfaces at room temperature. The product is environmentally friendly and free of acidic fumes, serving as a replacement for conventional hydrochloric acid-based derusting processes while preventing over-corrosion and hydrogen embrittlement of the steel substrate.

HH Die-Cast Aluminum Whitening Agent

Die-cast aluminum whitening agent, which can be used at ambient temperature, is suitable for cleaning and removing contaminants and oxide black spots from various aluminum alloys, high-silicon die-cast aluminum, and aluminum-magnesium alloys. After treatment with this aluminum whitening agent, the aluminum surface becomes clean and matte white, exhibiting a uniform aluminum alloy white color, and it effectively removes residues of release agents that have dried and hardened on aluminum parts after die casting. The aluminum whitening agent features simple operation and is environmentally friendly, replacing traditional acid pickling processes. No heating is required during cleaning, making it an eco-friendly cleaning product for whitening, decontaminating, and removing oxidation from high-silicon die-cast aluminum.

HH Die-Cast Aluminum Passivator

HH die-cast aluminum passivator is a passivation agent specifically formulated for aluminum alloys and die-cast aluminum, significantly enhancing their corrosion resistance. After passivation, die-cast aluminum alloys can achieve salt spray resistance of 72 to 360 hours, zinc alloys 48 to 72 hours, and aluminum extrusions 48 to 240 hours.

HH Die-Cast Aluminum Decontamination and Whitening Agent

Die-cast aluminum descaling and whitening agent can be used at ambient temperature and is suitable for cleaning and removing contaminants, oxide black spots, and discoloration from various aluminum alloys, high-silicon die-cast aluminum, and aluminum–magnesium alloys. After treatment with this aluminum whitening agent, the aluminum surface becomes clean and matte white, exhibiting a uniform aluminum alloy white finish, and it effectively removes residual release-agent residues that have dried and hardened on aluminum parts after die casting. This descaling and whitening agent features simple operation and is environmentally friendly; it replaces traditional acid pickling processes and requires no heating during cleaning. It is currently an eco-friendly cleaning product for whitening, decontaminating, and removing oxidation from high-silicon die-cast aluminum.
