Product Description Features Potential or Typical Uses
One-Part Moisture Cure RTV
Dow Corning
®
3-1944 RTV
Coating
Translucent; 1 part – no mixing required; moisture cure
(RTV) – no oven required; solvent-free – no ventilation
required; formulated for broader global compliance; UV
indicator for automated inspection; cure system can be
heat accelerable for faster in-line processing; medium
viscosity providing ow/ll/self-leveling after dispensing
process; Mil Spec A-46058 QPL (qualied product listing);
UL-94V-0 ammability rating
Good owability; room temperature
cure; no added solvents; UV
indicator for inspection; UL 94V-0
and Mil-A-46058
Sealing lids and housings where
grooves or other congurations
support a flowable material or where
limited flow is desired

6-1104 CV
Sealant
Translucent; 1 part – no mixing required; moisture cure
(RTV) – no oven required; solvent-free – no ventilation
required; cure can also be heat accelerated; non-ow after
dispensing process; high elongation value for vibration/
mechanical shock dampening and low stress; low volatility
for minimal weight loss under vacuum – proven for space-
grade applications
Non-owing; room-temperature
cure; low levels of volatile
condensable materials; high
elongation for added stress relief
Space-grade sealing and adhering
