Adhetron UV-Sil 3011 Dual-Curing Silicone Circuit Coating 1000 g

Adhetron UV-Sil 3011 is a dual-curing, silicone-based RTV compound developed for the potting, encapsulation, coating, and sealing of electronic parts. According to the official technical documentation, the product is one-component, non-corrosive, and cures under UV light or atmospheric moisture to form a very soft silicone elastomer structure. This dual-curing approach supports continued curing not only in areas directly exposed to light but also in shadowed regions, providing process reliability in electronic protection applications. According to official corporate information, Adhetron is a brand originating from Connecticut, USA, and the product is presented under the Pulsar Chem. Industry and Trade Co. INC. brand structure.

UV-SIL 3011 Technical Structure and Curing Profile

This product is defined in the technical datasheet as a dual-cure RTV silicone rubber and operates with a neutral cure oxime moisture-curing mechanism. Its ability to cure with UV-A, 365 nm UV LED, and moisture offers flexible application possibilities with a single product across different production scenarios. According to the official TDS data, a UV curing value of 120 seconds is given for a 2 mm layer thickness at a light intensity of 40 mW/cm², which is a significant advantage for electronic processes requiring controlled and rapid surface curing. In terms of flow behavior, the product’s hazy liquid appearance and viscosity range of 1500–2500 cP help provide balanced spreading in coating and filling applications.

UV-Sil 3011 Performance Features and Resistance Values

In its cured state, the material forms a very soft elastomer structure and has a Shore A hardness of 15. The stated operating temperature range of -40°C to +200°C indicates that the product can be used in electronic environments exposed to thermal fluctuations. On the electrical performance side, values of 4.7 x 10^15 ohm-cm volume resistivity, 400 volts/mil dielectric strength, and a dielectric constant of 2.67/2.68 are provided; these data support the product’s suitability for electronic circuit protection and insulation-focused applications. In addition, the water absorption value after 3 days is given as below 1%, and shrinkage after 72 hours at 60°C is stated as below 0.5%, showing that it offers a balanced profile in terms of dimensional stability and environmental resistance.

Application Method and System Compatibility

According to the official application description, the product is used for coating, filling, encapsulation, and sealing on electronic parts, pins, and similar technical components. Thanks to its one-component structure, it does not require mixing, which simplifies operation in terms of dispensing and process repeatability. Keeping surfaces clean before application and selecting the proper layer thickness directly affect both UV curing efficiency and the final coating integrity. While rapid surface curing is achieved in exposed areas, the continuation of moisture curing in shadowed regions provides a functional advantage especially in complex-geometry electronic systems.

Industrial Application Areas and Key Advantages

This dual-curing silicone compound can be used in areas such as electronics manufacturing, industrial electronics, automation equipment, and lighting technologies. Since pin coating, conformal coating, encapsulant use, potting processes, and LED-focused applications are clearly listed on Adhetron’s electronics and industrial solution pages, the product has a meaningful application profile in control systems, sensors, pin surroundings, module protection areas, and LED-based electronic assemblies. Its key advantages include its one-component structure, non-corrosive nature, process continuity in shadowed areas thanks to dual curing, and its ability to form a flexible elastomeric protective layer. Since no separate independent certification or test standard is specified in the publicly available official technical content, the product should be evaluated directly based on the performance values in the manufacturer’s technical datasheet; for storage, it is stated that it can be kept for up to 12 months at 4°C or below in unopened packaging.
