- Cleaning: Before the coating operation, make sure to thoroughly remove the dust and oil stains on the substrate surface.
- Maintenance or recoating: This product has excellent recoating performance. If re-coating is needed, clean the surface and reapply directly at the corresponding position.
(Note:
1-Allow each layer to dry before applying the next one.
2-To achieve the best waterproof effect, it is recommended to spray repeatedly for 2 – 3 times.
3-Before use, please shake it to maintain the uniformity of the liquid)
4-After spraying, the surface drying time is approximately 2 – 3 minutes. The surface can meet daily use requirements after drying.
5-Don’t let your circuit board be immersed in water for long when powered on.
6-use a dedicated circuit board cleaning solution to thoroughly clean the board

Excellent Safety
The Flywoo X30 waterproof spray is an environmentally friendly product that does not contain harmful substances. However, traditional three-proof paints may release volatile organic compounds (VOCs), which have certain impacts on the environment and human health.
Comparison to Traditional Conformal Coatings
The protective performance of the three-proof paint relies largely on the compactness of the coating. This is also the focus of the research and development for three-proof paint manufacturers. Moreover, the super-hydrophobic coating inherently possesses natural characteristics such as waterproofing, anti-short circuit, anti-corrosion, anti-salt spray, anti-mold, and anti-dust. Consequently, superhydrophobic materials are ideal alternatives to conformal coatings!
| The needs of the electronics industry | Superhydrophobic Coating | Conformal Coating |
| waterproof | The biggest feature of superhydrophobic iswaterproof | Depends on coating density |
| Short circuit prevention | Excellent anti-short circuit characteristics due torepellency of water / moisture / corrosive liquids | Depends on coating density |
| Corrosion protection | Natural repellency of water or corrosive liquids forexcellent corrosion protection properties | Depends on coating density |
| saltfog-proof | Excellent anti-salt spray properties due to naturalrepellency of salt spray | Depends on coating density |
| fungi-proof | Hydrophobic and dry surface will not harbor bacteria | Adding anti-mold additives, which will affectthe compactness of the coating |
| dustproof | Self-cleaning effect similar to lotus leaf to preventdust | No dustproof effect |
| radiating | Inorganic-organic composite coating to improve heatdissipation | Poor heat dissipation of polymer materials |
Huawei Case: Super Hydrophobic VS 3M Conformal Coating
| Comparison Items | Our Superhydrophobic Coating | 3M Conformal Paint |
|---|---|---|
| Thickness | ~20µm | ~40µm |
| Contact Angle | 160° | 80° |
| Wettability (water) | Completely non-wetting | Semi-immersion |
| Wet and Dry Cycle | No change in contact angle after 1000 times | After 100 times, the contact angle becomes 30° |
| Salt Spray Performance | 1000 h | 500h |
| Adhesion Level | 0 level | 0 |
| Anti-short Circuit Time (Accelerated Test in a Salt Spray Chamber) | 1500h | 1000h |
Based on the comparison above, this superhydrophobic coating clearly outperforms 3M’s conformal coating in various performance metrics, including:
1. Thinner coating thickness – The superhydrophobic coating only requires 20-50 μm, compared to 40-120 μm for the traditional conformal coating.
2. Higher hydrophobicity – The superhydrophobic coating has a contact angle of 160°, while the 3M coating is only 80°, indicating much stronger water repellency.
3. Superior durability – After 1000 wet-dry cycles, the superhydrophobic coating maintained its contact angle, whereas the 3M coating dropped to 30° after just 100 cycles.
4. Enhanced anti-corrosion and anti-short circuit performance – The superhydrophobic coating achieved 1000 hours of salt spray resistance and 1500 hours of anti-short circuit time, outperforming the 3M coating’s 500 hours and 1000 hours respectively.
These significant advantages make the superhydrophobic coating an ideal protective solution for the electronics industry. Its combination of thin profile, extreme water repellency, and outstanding durability and protective capabilities make it a superior alternative to traditional conformal coatings.
Excellent heat dissipation
The thickness of conventional conformal paint is 40 – 120µm, but our super-hydrophobic coating only needs 20 – 50µm.
| Resin Type | Acrylic Resin | Epoxy Resin | Silicone Resin | Polyurethane Resin | p-xylene | Our Superhydrophobic Materials |
|---|---|---|---|---|---|---|
| Thermal Conductivity (W/mk) | 0.2 – 0.8 | 0.2 – 1 | 0.8 – 1.2 | 0.35 – 1.1 | 0.2 – 0.5 | 3.3 |
| Thermal Resistance (10⁻⁴m²K/W) | 1 – 4 | 0.8 – 4 | 0.6 – 1 | 0.7 – 2.2 | 1.6 – 4 | 0.1 |
The data comparison indicates that our superhydrophobic material has an impressive thermal conductivity of 3.3 W/mK, which is significantly higher than common resin-based coatings. Additionally, its thermal resistance is only 0.1 x 10⁻⁴m²K/W, far superior to other materials.
This means that, compared to traditional coatings, our superhydrophobic coating can more effectively aid in heat dissipation for electronic devices, thereby enhancing overall thermal performance. This is particularly crucial for high-power electronic products.
In summary, with its excellent thermal conduction properties, our superhydrophobic coating can provide superior heat dissipation for electronic products, making it an ideal protective solution.
