    Grafenberg, Germany -- "It would be no problem to drive over a DC/DC-transformer, which has been insulated with our electro-casting resin, with a motor car - without breaking it," explained Dr Peter Gräter, development manager at Rampf Giessharze.

    In Gräter's laboratory, the latest polyurethane and epoxy-based casting com-pounds have been created, which the company will introduce at Electronica in Munich, 9-12 Nov. Rampf says the systems effectively protect power electronics and power supply systems against moisture, shocks and overheating and hence makes them suitable for use in hybrid and electric vehicles.

    Rampf Giessharze will be presenting three new products at the Electronica in November: RAKU-PUR 21-2551, and RAKU-POX 22-1010 and 23-1110. The systems, which are PU and epoxy-based, have one main objective: to protect electronics and thus safeguard the functional performance even under extreme conditions, whether for condensers, sensors, transformers, DC/DC-transformers, relays or other power electronics.

    Simple processing on commercially available two-component low-pressure mixing and dosing systems is possible, thanks to the use of non-abrasive fillers, Rampf notes. Complete solutions are also available in conjunction with its affiliated company, Rampf Dosiertechnik

    RAKU-PUR 21-2551 is a polyurethane-based two-component casting resin. The solvent and halogen-free system is UL listed for all colours and reactivities. Rampf says it provides optimal flame-retarding properties according to the UL94 fire protection ordinance, at a film-thickness of 1.5 mm. In addition, it is electrically conducting and has excellent insulation functions.

    Above-average temperature change stability (-40 deg C to 130 deg C), as well as a low tendency to absorb water round-off the property profile of the material. The pot-life is variably adjustable. Areas of application include the protection of sensors and circuit boards.

    The epoxy-based products are just as effective, says Rampf. The one-component electro-casting resin RAKU-POX 23-1110, as well as the 2-component system RAKU-POX 22-1010, excel with very good thermal and mechanical properties. This makes their use in the motor field, for instance, indispensable, says the company.

    Rampf will introduce its extensive product portfolio of electro-casting resins on PU, epoxy and silicone basis, 9 -12 Nov 2010, in Hall B2, booth 431 at the Messe Munich.

    PIC:Rampf is presenting three new electro-casting resins at Electronica 2010 in Munich, 9-12 Nov.
