Adhetron UV-Sil RTV 3044 Dual-Curing Silicone Rubber Compound 1000 g

Adhetron UV-SIL RTV 3044 Dual-Curing Silicone Rubber Compound 1000 g

Adhetron UV-SIL RTV 3044 is a dual-curing silicone rubber 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 elastomer structure. This structure provides reliable process continuity in electronic protection applications, since moisture curing continues even in areas where light cannot reach. The product is one of the technical silicone solutions offered under Pulsar Chem. Industry and Trade Co. INC. by the Adhetron brand, which has an R&D structure based in Connecticut, USA.

UV-SIL RTV 3044 Technical Structure and Curing Features

This product is defined in the official TDS as a dual-cure RTV silicone rubber, and its moisture-curing mechanism is specified as neutral cure oxime. Its ability to cure with UV-A, 365 nm UV LED, and atmospheric moisture provides flexible application possibilities with a single product across different production scenarios. The technical data list a clear appearance, viscosity of 8000–11000, and a specific gravity of approximately 1.05; this profile is especially suitable for electronic coating and filling processes requiring controlled flow. On the UV-curing side, the given value of 120 seconds for a 2 mm layer thickness at a light intensity of 40 mW/cm² shows that the product can be used in processes requiring rapid surface curing.

RTV 3044 Performance Profile and Resistance Values

In its cured state, the product forms a very soft elastomer structure, supported in the official table by a Shore A hardness range of 15–25. On the mechanical side, the stated tensile strength of 200 psi and elongation of 300% show that the material provides a flexible protective layer with movement tolerance rather than a rigid filler. In terms of thermal resistance, the operating temperature range is specified as -40°C to +200°C, which is an important technical advantage for use in electronic systems exposed to temperature changes. This performance profile offers a more balanced protection approach for circuit components exposed to vibration, expansion differences, and environmental effects.

Application Method and Compatible Systems

The product is applied on electronic parts and pins for coating, filling, encapsulation, and sealing purposes. Thanks to its one-component structure, it does not require mixing; after application, rapid UV curing starts in exposed areas, while atmospheric moisture continues the curing process in shadowed regions. This dual-curing principle enables safer process management in complex-geometry circuits, around pins, and in areas with partial shadowing. In the official product description, compatible systems are positioned as electronic parts, pin applications, and general industrial electronics processes.

Industrial Use Areas and Key Advantages

UV-SIL RTV 3044 can be used in electronics manufacturing, industrial control equipment, lighting systems, and general industrial electronic assembly processes. Its main application advantage is its ability to form a flexible protective layer on boards, modules, pins, and sensitive components requiring potting, encapsulation, coating, and sealing. The brand’s electronics-focused solution descriptions also emphasize that silicone-based products are used for flexibility, environmental protection, and the safety of sensitive components. The official technical documents do not additionally highlight any specific certification or test standard information; on the storage side, the product is stated to be storable for up to 12 months at 4°C or below in its original unopened packaging.
