【Applicable Materials】

Suitable for nano-silane treatment of surfaces made of steel, galvanized sheet, zinc, and aluminum alloys.

[Product Overview]

Silane treatment is an environmentally friendly and energy-efficient new technology for pre-coating surface preparation: it is eco-friendly, energy-saving, free of harmful heavy-metal ions, and phosphate-free. Compared with conventional phosphating, it features a simpler process, a shorter flow, fewer steps, the elimination of the surface-conditioning step, and no need for heating. 
The silane treatment process generates no sludge, thereby eliminating the need for solid-waste disposal in the pretreatment stage and effectively extending the tank-replenishment interval. This leads to increased production efficiency, reduced ongoing equipment operating costs, reusable bath solutions, simplified control, and lower overall costs. 
The treated workpieces exhibit excellent adhesion to paint coatings and can be used as a pre-treatment for coating various materials, including steel and galvanized parts, thereby replacing conventional phosphating and hexavalent chromium passivation.

【Product Features】

1. Phosphate-free, slag-free, and free of heavy metal ions; complies with the EU RoHS standard and meets wastewater discharge standards. 
2. Enhances paint adhesion to the substrate, achieving optimal results without heating the bath solution. 
3. Eliminates the conventional surface conditioning and post-phosphating water rinsing steps, as well as associated equipment such as heating units, slag-removal tanks, and phosphating wastewater treatment systems. 
4. Silanization significantly reduces processing time compared with phosphating, thereby increasing production efficiency and lowering continuous equipment operating costs. 
5. Enables recycling, reduces costs, and alleviates the burden on wastewater treatment; operates at ambient temperature, lowering energy consumption and resulting in a 20–30% reduction in water usage annually.

【Application Areas】

1. Applicable materials: steel, galvanized sheet, zinc, and aluminum alloy. 
2. Applicable industries include: metal processing, hardware and electrical appliance manufacturing, hardware and electronics, aerospace components, automotive parts, mobile phone accessories, hardware furniture, medical equipment, and telecommunications devices.

【Precautions】

1. Strictly control the pH value within the process specifications (especially for zinc-aluminum alloy parts). 
2. When the bath pH is less than 8.0, the adhesion between the workpiece and the coating will decrease.

[Test Method] 
1. The protective performance of silane coatings can be evaluated using the test methods employed for phosphating coatings, namely alkali titration and colorimetry. 
2. The silane coating on the workpiece can be tested using methods such as the cross-cut test or impact testing, and observed under a digital microscope. 
3. The continuity of the silane-treated film on metal surfaces can be assessed using X-ray fluorescence analysis or a silane treatment film detection reagent.
