About This Product

■Features

Prevents dirt and dust generated from the film surface. Highly corrosion-resistant hexavalent chromium-free chemical conversion treatment specialized for aluminum die casting Do you want to improve corrosion resistance but cannot use hexavalent chromium due to usage restrictions? Are you worried that chromium-free treatment does not provide good corrosion resistance? The highly corrosion-resistant chemical conversion treatment (ACF-D treatment) developed by our company is available in two types: trivalent chromium type and non-chromium type, and both are environmentally friendly coatings that do not contain hexavalent chromium and have excellent corrosion resistance. In particular, the ACF-D650 treatment developed for ADC12 material has a semi-gloss base color to light brown, generates less dirt and dust, and can improve adhesion and corrosion resistance.

■Overview of hexavalent chromium-free chemical conversion treatment [ACF]

Chemical conversion treatment of aluminum die casting is used in various fields such as semiconductor, medical equipment, and precision parts industries. However, if the product has a complex structure such as aluminum die-casting or casting, impurities such as dirt and dust generated from the surface will fall off and adhere to the equipment, causing malfunctions and affecting the operating status. . Until now, chromate treatment using hexavalent chromium has mainly been carried out to improve corrosion resistance and adhesion, but in recent years, hexavalent chromium, which is toxic, has been used to protect the natural environment and prevent health hazards. The transition to chromium-free processing solutions is progressing. However, it is difficult to maintain sufficient corrosion resistance in aluminum die casting with chromium-free treatment. In order to achieve both chromium-free treatment for aluminum die casting and improved corrosion resistance, we have developed a highly corrosion-resistant chemical conversion treatment (ACF treatment) using two types: trivalent chromium-based and chromium-free. The ACF-D650 treatment, developed especially for high-silicon materials such as ADC12, has a semi-gloss base color to light brown color, generates less dirt and dust, and has adhesion and corrosion resistance equivalent to chromate. I am.
