PRODUCT DESCRIPTION:
DOW‑738 (formerly Dow Corning 738, now sold under the DOWSIL brand) is a high‑performance, one‑component electrical sealant designed for bonding and sealing electrical assemblies and components. In its 3 oz tube format (often part number D632087), it provides a non‑flowing, moisture‑cure silicone adhesive that forms a durable, flexible rubber upon cure. Its combination of high elongation, good tensile strength, and excellent dielectric strength makes it ideal for sealing housings, connections, printed circuit boards, motors, generators, and other electrical and electronic equipment without the need for ovens or mixing.
TYPICAL APPLICATIONS:
Sealing and bonding electrical enclosures and junction boxes
Insulating printed circuit boards and electronic assemblies
Potting or bonding components in motors, generators, and transformers
Sealing around wires, terminals, conduit ends, and connectors
General electrical assembly and maintenance work
Protection of components exposed to humidity or vibration
