SY-203 Acidic Sandblasting Agent

SY-203 acidic sandblasting agent is a slightly acidic solid used as a pretreatment to produce a uniform, fine sandblasted finish on aluminum surfaces; it contains fluorides and surfactants. It is particularly suitable for aluminum surfaces that have undergone mechanical polishing, electrolytic polishing, or chemical polishing, delivering an impeccable matte finish.

SY-202 Alkaline Degreaser for Aluminum

SY-202 alkaline degreaser for aluminum is a concentrated, silicate-free, mildly alkaline powder detergent specially formulated to remove surface oils and oxide films from aluminum and aluminum alloys. The wetting agents in SY-202 can be easily rinsed off metal surfaces without emulsifying oil contaminants—unless the oil itself contains an emulsifier.

SY-201 Alkaline Degreaser for Aluminum

SY-201 aluminum‑acid degreaser is a colorless liquid, commonly referred to as “aluminum acid degreaser.” It was specifically developed to streamline the pretreatment process for aluminum alloys, offering the same functionality as the conventional three‑step method—degreasing, alkaline etching, and neutralization. Moreover, it leaves the surface of aluminum and its alloys free of dullness, preserving the original luster of the base material. Notably, its corrosion rate is only one‑fifth that of the traditional process.

SY-132 Aluminum Mirror Polishing Agent (Fine)

SY-132 aluminum mirror‑finish polishing agent (premium grade) is a colorless, viscous liquid that contains no lead, chlorinated paraffins, hexavalent chromium, or their compounds. It effectively removes oil and rust while delivering exceptional lubrication and abrasive performance. It restores metal surfaces to a luster surpassing the original finish without leaving any scratches or blemishes. This polishing fluid is specially formulated for use in vibratory finishing machines to process various aluminum alloys. When used in conjunction with polishing stones, it accelerates the removal of machining marks, burrs, and flash from workpiece surfaces, reduces surface damage caused by contact with the stones, and delivers outstanding results on the polished surfaces of aluminum alloys, stainless steel, copper, and other metals.

SY-131 Aluminum Mirror Polishing Compound (Coarse)

SY-131 aluminum mirror‑polishing compound (coarse) is a colorless, viscous liquid. When used with a polishing machine, it enables fine grinding and mirror‑finish polishing of aluminum alloy surfaces, enhancing polishing efficiency while removing surface oils and achieving an initial bright finish. It also provides rust protection, maintains luster, and offers lubrication to reduce abrasion, helping the workpiece attain an ideal level of gloss. It delivers comparable, outstanding results when applied to stainless steel, copper, and other metal surfaces. This product is non‑toxic, non‑oxidizing, and non‑flammable, with excellent detergency, anti‑rust properties, and cleaning performance. It can restore metals to a brighter finish than their original state, and its wastewater discharge complies with environmental regulations.

Highly wear-resistant, sun-resistant decorative oxide film

Conversion coating category: High‑wear‑resistant, sunlight‑resistant decorative oxide film Application area: Self‑lubricating black oxide coating for automotive sunroof slide rails Partner: All automotive friction components have this type of requirement Advantages of the conversion coating: Currently, we are in discussions with Changchun Hengtuo Group to supply a self‑lubricating black oxide coating for sunroof slide rails to the German‑owned Webasto company, which holds a 65% global market share in sunroofs. Samples are undergoing nine performance tests. Our oxide‑coating process is well‑established, and we are confident of securing this project; within the year, we plan to build a dedicated production line in Changchun with an annual capacity of 800,000 sets. Should SAIC have similar requirements, we would welcome the opportunity to collaborate.

High wear resistance, low surface roughness oxide film

Conversion coating type: high‑wear‑resistant, low‑roughness oxide film Application areas: valve bodies made of high‑silicon aluminum alloys Partners: automotive component manufacturers producing transmission housings, air‑conditioning pumps, brake pumps, and more Conversion coating advantages: Currently in production are ADC12 brake pump housings, automatic transmission valve bodies, and A390 swash plates for air‑conditioning pumps, all manufactured on a dedicated automated high‑silicon aluminum oxidation line. The challenge with this type of oxide coating lies in its stringent performance requirements, which exceed the capabilities of standard aluminum anodizing processes.

High-gloss, acid- and alkali-resistant, oxidation-resistant film

Conversion coating type: High-gloss, acid- and alkali-resistant anodized film Application areas: Roof rack bars, door trim strips Partners: Demand exists for four Kia models as well as comparable B‑segment vehicles Advantages of the conversion coating: In 2016, processed rack samples and a small batch of 300 units passed GM’s ten‑point performance tests, and all on-site process‑technology and production preparations were completed. However, the project was subsequently halted when DEEZEE, a U.S. company, canceled its investment plans in China.
