Absolute process reliability

LED light potting

Bubble-free dispensing of silicone and polyurethane

Compared to an incandescent light bulb, an LED lamp consumes less energy for the same light output, generates less heat and is significantly smaller and less susceptible to shocks. Furthermore, it has a much longer life. The increasing use of LEDs is even expanded by applications that would not be possible without potting. The potting compounds used for such applications are polyurethane (PU) or silicone-based two-component solutions. They are intended to protect the LEDs against extreme temperatures, moisture, vibrations and mechanical damage. LEDs are also used in fields where maximum reliability is required and maintenance-free operation plays an important role.

Intelligent solutions by DOPAG
The comprehensive DOPAG portfolio of two-component compound metering and mixing systems for manual and automated application ensures absolute process stability. The benefits offered include the precise maintenance of the specified mixing ratios, a high metering accuracy, a high flow rate and bubble-free application that is the decisive prerequisite to ensure stable potting. As seen both from the ecological and economical perspectives, DOPAG metering and mixing systems promote a sustainable production process. The materials to be processed are mixed based on the specific demand which means material consumption and waste disposal costs can be reduced. The use of flushing agents is not required.

Absolute process stability
LEDs are used for various applications that range from flashlights and traffic lights to headlamps and taillights in vehicles and to street lighting. They can also be found in lighting systems for damp interiors and swimming pools and are used for creating optical effects in showcases. The potting compound is selected depending on the requested properties such as hardness, vibration resistance and thermal stability. Different colors are possible as well. For translucent LED applications, a transparent or opaque clear potting compound is used.

In Potting, resins such as silicones, polyurethanes or epoxy resins are used in liquid form. For the production process, DOPAG offers various metering and mixing systems.

  1. eldomix


    The eldomix 100/600 range of systems are compact, solvent free, gear pump driven metering and mixing systems.

  2. variomix


    The variomix range of systems are solvent free, compact, pneumatic or hydraulically driven piston pump metering and mixing systems.

  3. vectomix


    Vectomix is used to handle multi component materials. Due to its compatibility and modularity, two vectodis single component piston metering with equal or different sizes are used.

With dynamicLine and the new dynamic mixing head, DOPAG offers an efficient solution for all applications relating to gasketing.

  1. Dynamic mixing head

    Dynamic mixing head
    The dynamic mixing head with its new valve technology has been designed for mixing of low to  high-viscosity polymeric reaction substances for foaming, bonding, sealing, and potting.
