Sealing Fittings Explosion-Proof, Dust-Ignition-Proof
Preparation
Applications
T&B Red•Dot
®
sealing cement is used for making seals in sealing fittings. The insulation
in the conductors sealed in the cement may be approved thermoplastic or rubber, with
or without lead covering. The sealing cement should not be used for insulating.
Characteristics
T&B Red•Dot
®
sealing cement is not affected by gasoline, alcohol, acetone, ether,
naptha, petroleum, benzol or lacquer solvent.
Preparation
(1) Use a clean mixing vessel for each batch.
(2) Thoroughly mix powder before adding water.
(3) Do not use if temperature is below 40° F.
(4) Mix 1 part water to 2 parts cement.
(5) Allow cement to set for 72 hours before use.
Standard Dams
(1) Push the conductors away from the filling opening and force them apart so that they
do not touch each other or the walls of the fitting or conduit along their length. If the
conductors do touch, the sealing cement will not form a closed path between them.
(2) Force the packing fiber between each conductor and the inside walls. Be sure that the
dam is strong enough and tight enough to prevent the considerable weight of the fluid
sealing cement from seeping out.
Pouring
(1) Pour the mixed cement into the fitting slowly so as not to trap air in the seal.
(2) Replace the close-up plugs to ensure that they engage not less than 5 full threads.
