Tailored specifically for high-load sedimentation scenarios involving iron powder, ensuring that the glass of photovoltaic modules remains clean and maintains efficient power generation performance even in extreme industrial environments.
Sysmyk® Nano-coating for photovoltaic glass, specifically designed to prevent rust and featuring low surface energy (room-temperature curing, two-component).
Ⅰ Product Code ZCP0043, ZCP0044
Ⅱ Product Features ZCP0043 is a high-performance, two-component nano-coating specially developed by HysenMec for steel metallurgy and heavily polluted industrial environments. This product features an advanced polymer-based functional resin matrix combined with a precisely engineered nanocomposite system. Through low-surface-energy interfacial engineering, it achieves exceptional anti-fouling and corrosion-resistant properties. When applied to the surface of photovoltaic module glass, this coating significantly reduces the adhesion and corrosion caused by iron powder, rust, and acidic aerosols on the glass surface, effectively preventing pitting and loss of transparency while maintaining long-term high light transmittance. After application, the coating can boost power generation efficiency by at least 15% and markedly slow down the rate of pollutant deposition, more than doubling the interval between cleanings. As a result, it reduces both labor costs and water consumption for cleaning, enhancing the operational safety and maintenance reliability of rooftop photovoltaic systems. Even in extremely harsh conditions such as those found in steel plants—characterized by acid mist and coke dust—this coating continues to perform reliably, significantly extending the service life of the modules.
◼ Industry-specific protection for the steel industry: For iron powder, rust, and acid mist deposition—common issues on the surface of rooftop photovoltaic modules in steel plants—the coating effectively inhibits pitting corrosion and the electrochemical microcell effect, thereby preventing glass from being eroded by rust.
◼ Low-surface-energy anti-fouling mechanism: With a surface energy significantly lower than that of conventional coatings, this mechanism markedly reduces the initial adhesion of particulate matter (such as coke dust, black carbon, lime powder, and sulfate/chloride salts), endowing the component with self-cleaning properties that allow it to be “cleaned instantly by rain.”
◼ Exceptional acid-fog resistance: Long-term testing has demonstrated that the coating can withstand acidic aerosol environments such as HCl and SO₂, maintaining stable transparency and structural integrity.
◼ Combined advantages of optics and weather resistance: The coating boasts high transparency and excellent reflectance control, ensuring that photovoltaic glass maintains high light transmittance even in heavily polluted environments, thereby stabilizing the power output of the modules. The coating’s service life is no less than 5 years.
◼ Systematic solution: Must be used in conjunction with the dedicated primer ZCP0044 to enhance adhesion to glass substrates and improve the overall coating life and reliability.

VI Technical Parameters
Ⅶ Construction Method
Pre-construction preparation
Clean the surface of photovoltaic glass using QCP0091ST-3 (a multi-functional dirt remover specifically designed for photovoltaic glass). Directly spray the dirt remover onto the glass surface, wait 30 seconds to 1 minute, and then use cleaning equipment specially designed for photovoltaic glass to perform the treatment. After completion of the treatment, rinse thoroughly with clean water and use pH test paper to ensure that the surface has a neutral pH.
The treated surface should be constructed as soon as possible to prevent dust from re-attaching.
After ensuring the surface is completely dry, proceed with spraying or brushing on the ZCP0044 primer coat. Wait 20–30 minutes before applying the ZCP0043 topcoat.
Construction method
Primer application
Apply ZCP0044 by spraying or brushing according to the product instructions. After the coating has surface-dried (approximately 30–50 minutes), proceed with the application of the topcoat.
Topcoat application
After uniformly mixing ZCP0043A and ZCP0043B at a ratio of 9:1, you can proceed with construction. The mixed material must be used within 2 hours; otherwise, it may gel and become unusable.
Blocking processing
If the construction environment involves continuous pollutant emissions, the coated photovoltaic modules must be covered with a waterproof and breathable membrane until the coating has fully cured (24–48 hours), after which the membrane can be removed.
Environmental condition requirements
The substrate temperature must be at least 3°C (preferably ≥5°C) above the dew point temperature; otherwise, construction is prohibited to prevent moisture from affecting the coating’s adhesion and curing performance.
Relative humidity should be <85% (optimal <75%). Construction is prohibited if the humidity is too high, to prevent moisture from adversely affecting the curing and adhesion of the coating.
Construction is prohibited in rainy conditions and environments with high humidity to ensure coating quality and construction performance.
Operations and Maintenance Recommendations and Precautions
(1) Cleaning Agent Selection
·We recommend using clean water as the preferred choice: For daily maintenance, try to use clean water whenever possible to ensure safety, environmental friendliness, and lower operation and maintenance costs.
·Use a dedicated cleaning agent when contamination is severe: When surface oil stains, salt spray deposits, or acidic contamination are particularly heavy, we recommend using Sysmyk® QCP0096 Photovoltaic Neutral Cleaning Agent. This product has passed coating compatibility testing and can significantly enhance cleaning performance without compromising the integrity of the coating structure.
·Prohibition of Acidic and Alkaline Cleaners: The use of acidic, alkaline, or abrasive-containing cleaners is strictly prohibited to avoid chemical degradation, loss of gloss, or failure of the coating.
(2) Cleaning Cycle
·General industrial environments: It is recommended to clean every 1–2 months.
· In heavily polluted or acid-fog environments: It is recommended to clean once a month.
· Acid rain or extreme seasons (such as the plum rain season or periods of high humidity): It is recommended to clean every 2–3 weeks.
·Flexible adjustment: The scheduling should be tailored based on local environmental monitoring data (PM2.5 levels, frequency of acid rain, and wind-sand intensity) as well as the actual pollution level of the components, to avoid excessive cleaning.
(3) Use of high-pressure water guns and cleaning equipment
·Injection pressure: ≤ 0.5 MPa;
· Nozzle-to-glass distance: Maintain ≥ 30 cm to avoid directly spraying the coating surface;
·Cleaning medium: Only clean water or the approved Sysmyk® QCP0096 neutral detergent is permitted;
·Precautions: Do not use hot water or mix in other chemicals to prevent thermal stress damage to the glass and degradation of the coating.
(4) Cleaning Robot Usage Guidelines
· Operating mode: It is recommended to use the low-speed operating mode to reduce damage to the coating caused by frequent friction.
· Cleaning medium: The robot’s spray system should be connected to clean water or a dedicated neutral detergent. The use of liquids from unknown sources or highly corrosive substances is strictly prohibited.
·Cleaning materials: Use only soft cleaning roller brushes or cloth strips, and avoid hard bristles or high-friction materials.
·Operation and Maintenance Inspection: Before each cleaning, check whether the robot’s nozzles and brush rollers are clean to prevent sand and gravel from getting trapped and causing scratches on the coating.
(5) Manual cleaning operations
·Detergent usage: When cleaning manually, prioritize using plain water. For higher efficiency, you can use the Sysmyk® QCP0096 neutral detergent in combination.
·Tool requirements: It is recommended to use soft cloths, sponges, or rubber squeegees; avoid using hard tools such as blades, sandpaper, or steel wool.
·Operating guidelines: Wipe gently, apply even pressure, and avoid forcefully wiping on dry surfaces to prevent microscratches.
(6) Climate condition limitations
·Suitable weather: Cleaning should be performed on clear days or under low-humidity conditions (relative humidity ≤ 80%).
·Prohibited cleaning conditions: Cleaning is prohibited on rainy days, during high-wind conditions, or in environments with high humidity to prevent water stains from lingering, contaminants from redepositing, and deterioration of coating performance.
(7) Regular Testing and Evaluation
·It is recommended to conduct performance testing every six months. The testing items include: reflectance—measured using the intelligent reflectance meter BGD583;
Water contact angle (refer to GB/T 14293); simultaneously, in conjunction with power generation data from the power plant’s SCADA system, comprehensively evaluate the long-term performance enhancement effect of the coating.
(8) Injury and Repair
·Common damages: such as scratches, localized flaking, and stubborn contamination that cannot be removed;
·Handling method: When coating damage is detected, promptly contact the contractor or manufacturer and employ a professional repair procedure (recoating or localized touch-up).
