Potting Compounds from Permacol
Permacol casting resins are applicable in many different applications. Compared to adhesives, casting resins are in general not used in thin layers, but for casting, potting, encapsulation and molding applications. The main application of casting resins is to protect against adverse effects of mechanical, chemical, or thermal influences.
Epoxy casting resins offer excellent electrical properties and are applicable in many electrical and optical systems. Pot life decreases if the mixed amount of casting resin increases, because epoxies react exothermally.
Polyurethane casting resins offer good shock resistance and electrical insulation properties, and are applicable for electronic applications.
Silicone casting resins are flexible and offer excellent vibration and shock resistance. These resins also offer good electrical and insulating properties. Faster curing is possible at elevated temperatures.
Adhesives from Permacol
Bonding of SMD components on printed circuit boards. Permacol SMD adhesives are applicable for temporary bonding of electronic components on PCB's before soldering in the solder wave. A drop of adhesive is applied either on the PCB or under the component. This will hold the two together, even before curing, due to the wet strength (green strength). Curing is done very quickly; afterwards the solder connections are made. Solder is needed for electrical contact, but is rarely required to withstand shear forces, where SMD adhesives contribute to a better fixation of the components. Important properties like viscosity and wet (green) strength make the usage of these adhesives preferable.
Applicable where electrically conductive bonding is desired. Permacol® one- or two component electrically conductive adhesives are applicable where an electrically conductive bonding is desired. Applications might include bonding lead wire to electrodes, solder paste replacement in the assembly of SMD's, die attachment and repair of conducting paths. Besides electric, there are heath conductive adhesives for applications where it is needed, such as heat sinc or transit.
Permacol solvent-free UV-adhesives are particularly designed as high performance industrial materials for sealing, bonding, coating and potting. They are used in many fields, including electrical equipment, electronics, automotive industries, optics and others. When exposed to ultraviolet rays of 300 to 400 nm wavelength generated by a UV irradiator, the adhesive polymerises and cures in approximately 30 seconds to form a tough cured product characterised by excellent flexibility, adhesive strength, anti-corrosiveness, thermal resistance and electrical characteristics.
