DOWSIL 1-4105 Conformal Coating is suitable for use as a protective coating for rigid and flexible circuit boards
Solventless heat cure conformal
coatings are designed for rapid
processing at low temperatures
(below 125°C). They require some
heating to cure, offering long bath at
room temperature. Like the roomtemperature-curing
elastomers, these
products offer optimum stress relief
Dow corning DOWSIL™ 340 Heat Sink Compound
Dow thermally conductive compounds are grease like silicone materials, heavily filled with heat-conductive metal oxides. This combination promotes high thermal conductivity, low
bleed and high-temperature stability. The compounds are designed to maintain a positive heat sink seal to improve heat transfer from the electrical device or PCB system assemblies
to the heat sink or chassis, thereby increasing the overall efficiency of the device. or PCB system assemblies are continually designed to deliver higher performance. Especially in the area of consumer devices, there is also a continual trend towards smaller, more compact designs. In combination these factors typically mean that more heat is generated in the device. Thermal management of PCB system assemblies is a primary concern of design engineers. A cooler device allows for more efficient operation and better reliability over the life of the device. As such, thermally conductive compounds play an integral role here. Thermally conductive materials act as a thermal “bridge” to remove heat from a heat source (device) to the ambient via a heat transfer media (i.e. heat sink). These materials have properties such as low thermal resistance, high thermal conductivity, and can achieve thin Bond Line Thicknesses (BLTs) which can help to improve the transfer of heat away from the device.
DOWSIL 3145 RTV MIL-A-46146 Adhesive/Sealant – Gray
DOWSIL 3145 RTV MIL-A-46146 Adhesive/Sealant – Gray is suitable for:
Sealing openings in modules and housings
Adding mechanical stability to individual components
Assembly of components on PWBs
Sealing in and around wired and electrical leads Yoke assembly
DOWSIL 1-2620 Low VOC Conformal Coating version is supplied with a lower VOC content compared to that of the DOWSIL 1-2620 Dispersion and has equivalent Mil spec, IPC-CC-830 and UL recognitions.
RTV elastoplastic conformal coatings have firm, dry surfaces for better handling and
abrasion resistance after cure. Various viscosity versions facilitate different application
methods. They require atmospheric moisture to cure (no ovens) and their cure rates can be
accelerated by mild heat. Conformal coatings are materials applied in thin layers onto
printed circuits boards or other PCB system assembly substrates
