Pre-potting Preparation: Calibrate scales, prepare potting tools, cleaning tools, check machine settings, check vacuum pump force, etc.
Product Pre-treatment: Place product on a level surface or fixture. Remove dust, clean, degrease, and dry if necessary.
Accurate Proportioning: Manual operation requires precise mixing according to the specified ratio and recording. Machine potting requires calibrated ratios and first-article confirmation is recommended.
Mixing & Stirring: Manual operation requires thorough stirring or using electric stirrers to ensure homogeneous mixing. Machine potting requires sufficient stirring speed, adjust as needed.
Uniform Potting: Manual operation should be done in small, multiple batches to ensure uniformity. Machine potting should follow the programmed path for quantitative dispensing.
Inspection or Secondary Potting: After potting, visually inspect as needed. Perform touch-up, bubble removal, or secondary potting if required.
Curing: Allow the potted and inspected products to cure at room temperature or with heat assistance (recommended 60°C if needed), according to product and process requirements.
Final Product Confirmation: Perform visual inspection and performance testing as required by the customer.
Hardener: Typically 5KG/ 10KG / 20KG/ 200KG metal or plastic drums.
Resin: Typically 5KG/ 10KG / 20KG / 200KG metal or plastic drums.
Q1: Does the transparent nature of the compound affect its protective qualities?
A1: No, the transparency of the polyurethane potting compound does not compromise its protective features; it still provides excellent insulation and environmental protection while allowing visual inspection of the encapsulated components.
Q2: Can this potting compound be used for outdoor electronic applications?
A2: Yes, the weather-resistant properties of this transparent polyurethane potting compound make it suitable for outdoor use, providing protection against UV rays, rain, and temperature fluctuations.
Q3: What are the main features of the Weather-Resistant Transparent Polyurethane Potting Compounds?
A3: This potting compound offers excellent weather resistance, high transparency, strong adhesion, and durability, making it ideal for protecting electronic components from moisture, dust, and environmental damage.
Q4: What types of electronics are compatible with this potting compound?
A4: It is compatible with a wide range of electronic components, including circuit boards, sensors, connectors, and LED assemblies, especially those requiring clear encapsulation and protection from harsh environmental conditions.
Q5: Is the compound easy to apply and cure?
A5: Yes, the potting compound has good flow characteristics for easy application and typically cures at room temperature, forming a tough and flexible protective layer.
