Conductive adhesive
AS filled silicone adhesives are generally employed as caulking materials to fill voids, surface imperfections on mating surfaces or to retain a conductive gasket in a position during assembly. Most conductive gaskets depend on flat, accurate and clean mating surfaces to provide a positive, low impedance bond and the additional use of conductive adhesives should be avoided wherever possible.Our AS Series of one-part conductive particle filled room temperature curing (RTV) silicone rubber adhesives is available using standard silicone and flurosilicone base compounds combined with a selection of particle fillers to produce a readily extrudable paste which self-cures when exposed to atmospheric moisture. Once the thixotropic paste is fully cured it provides excellent adhesion and low volume resistivity.
Shelf life is up to one year if kept in the original packaging and stored in a dry atmosphere below -23ºC.
AS adhesives should be injected under pressure if possible, and, where used as or with a gasket medium should be retained under pressure whilst curing. This enhances the conductivity of the compund. Care should be taken when handling the compound as contact can irritate the skin and eyes.

Other products from this member
Fully laminated windows
Fully laminated screened windows combine the physical strength and optical clarity of laminated glass or plastic with the shielding effectiveness of fine wire gauze.
Conductive silicone
Our E Range gaskets are constructed from silicone containing metal powder fillers which combine to produce high levels of attenuation with excellent environmental shielding and a high level of conductivity.
Elastomer-cored knitted wire meshes
P & P Technology's KE Series elastomer-cored knitted wire meshes consist of two layers of knitted wire over a low-closing-force rubber or elastomer core and offer the same shielding effectiveness of all-mesh types.
Attenuation vents
P & P Technology's VH Series of lightweight aluminium honeycomb attenuatung ventilation panels comprise of forms of conductive airflow media retained within an aluminium extrusion. They are designed for use in racks and other forms of commercial enclosure.
Aluweave - versatile gaskets
Aluweave is a versatile, highly conductive gasket medium produced by filling a woven aluminium mesh with either silicone, flurosilicone or neoprene rubber. It is particularly useful where thicker gaskets are unsuitable but, because it is woven, it is unsuitable for 'landwidths' of less than 3mm for diecut gaskets. Surface irregularities should not exceed 0.05mm.
Connector Gaskets
P & P Technology manufacture a wide range of connector gaskets, including precision diecut gaskets made from a selection of materials, both conductive and non-conductive. Gaskets can be tailor made to meet individual requirements.
Monex - expanded monel foil
Monex is expanded Monel foil filled with silicone rubber. The exposed foil surface provides excellent conductivity combined with good corrosion resistance. Monex is also 'thin' gasket medium, similar to Aluweave, and is particularly suitable for connector or waveguide gaskets where a pressure seal and EMI shield is required.
High performance RFI vents & filter composites
P & P Technology's VP Series of honeycomb ventilation panels can be custom manufactured from steel, brass or stainless steel. When selecting the material, corrosion resistance relevant to the application environment should be considered along with the attenuation requirements.
Silshield - Oriented wires in silicone
Our S Range silicone rubbers combine excellent environmental protection with a high level of shielding effectiveness. These products incorporate a matrix of vertically oriented wires which pierce both flat faces of the elastomer and provide around 100 contact points per square centimetre.
Twinstrip knitted or cored mesh gaskets
Twinstrip is a combination of knitted or cored mesh gasket with a non-conductive environmental seal. The wire mesh types used are Monel, Aluminium, TCS and Stainless Steel and the permutations of wire and elastomer combinations are almost endless providing a wide range of environmental, water, dust and pressure seals.
Airfilters with dustfield
Our VF Series of RFI vents combine the benefits of an attenuation vent panel with the properties of a dustfilter in a single frame, unlike the VB Series which utilises separate units fixed together in-situ.
Shielded windows
Fully laminated (WF Series) screened windows combine the physical strength and optical clarity of laminated glass or plastic with the shielding effectiveness of fine wire gauze.
Knitted mesh with carrier
Our KM series gasket strip and frame materials consist of a slotted aluminium extrusion carrier into which a solid or elastomer cored knitted mesh gasket is clamped. These ready-to-fit, semi-rigid gasketing profiles help to avoid the problems often encountered when fitting adhesive-backed or plain mesh gaskets.
Vent/filter composites
P & P Technology's VB Series of EMC vents / filter assemblies are composites of the VH Series honeycomb attenuation vents and demountable dustfilter panels containing a demembraned polyurethene filter media.
Edge bonded shielded windows
A low cost range of windows offering the same high level of EMI shielding performace as our range of fully laminated windows (WF Series) but with edge lamination only.
Other products at Electrical & electronic components > Electronic filter > EMI/RFI shields
Knitshield KP Series Knitted Mesh
Knitted wire meshes are produced from a single continuous filament and produce very high levels of EMI shielding performance when evenly compressed between two metallic contact surfaces.
Metweave - Woven Fabric Gasketing
P & P Technology's MW Series of ultra soft-fabric wrapped shielding profiles utilises a highly conductive and durable impregnated fabric formed around a sponge or foam core to create a very versatile low compression gasket medium.
Conductive Foil Tapes
P & P Technology's range of conductive foil tape offers a cost effective solution to EMC shielding. Tapes are available in both copper and aluminium with a conductive adhesive. The tapes can be used to seal joints on enclosures and for ground termination between panels on shielded rooms.
EMI shielding gasket
Fabric over foam gasket is made of high conductive and anticorrosive fabric, with low compressibility PU foam inside, and produced by precise process.
