Description
Dow Corning 3140 RTV Coating Clear is a one component, room temperature curing, solvent free coating that is used for pin sealing, increased solder joint coverage, thin section encapsulation, and protecting sensitive components from corrosion. It is self leveling, flowable, and flame resistant. 90 mL Tube.
Typical Use: Supplied at a higher viscosity, this material cures to a tough, abrasion-resistant elastomer for improved pin/solder joint coverage and thin-section encapsulation.
