GENERAL DESCRIPTION
The OMEGABOND OB-400 High Temperature Air Cement
is a sodium silicate base, one-part ceramic cement which has
many exceptional characteristics including:
• Resists temperatures to 1427°C (2600°F)
• Resists oil, solvent and most acids (except hydrofluoric)
• Heat conductive and thermal shock resistant
• Excellent electrical insulator
• Adheres to metals, ceramics, glass, porcelain and most
other surfaces
• Excellent mechanical bonding characteristics
• Ceramic-like body
OMEGA’s OB-400 cement is an electrical refractory cement
used for coating resistors, coils, electric heating elements,
furnaces, and also for embedding resistance wire. It replaces
other insulating materials such as varnish, enamel or mica.

HANDLING INFORMATION
CAUTION
• Avoid prolonged breathing of vapors-work in well-ventilated
area
• Protect skin against contamination
• Protect eyes against contamination
• Do not take internally
OMEGABOND® 400 Powder is a harmful dust. Avoid
breathing dust by using respirators. Avoid contact with eyes
or skin by wearing gloves and goggles or a face shield.
Wash thoroughly with soap and water after handling. Keep
containers closed.
SHELF LIFE
OMEGABOND® 400 Powder has a shelf life of 12 months
from date of manufacture, when stored in unopened, tightly
sealed containers in a dry location at 21°C (70°F).
SOLVENT
be applied should be clean and free of dirt or grease. Apply
several coats where heavier layers are desired, allowing
each coat to dry before application of the next coat. Do not
apply OMEGABOND 400 cement in thickness greater than
1/4”. OMEGABOND 400 cement can be applied by brushing,
dipping and spraying.
Porous substrates should be dampened with OMEGABOND®
Thinning Liquid (Part No. OB-TL), prior to application of the
mixed cement.
CURING
OMEGA’s OB-400 cures at room temperature by air drying
in 18-24 hours, depending upon thickness and consistency.
Cure time can be accelerated by low temperature oven
drying at 82°C (180°F). If the cement is to be exposed to
elevated temperatures, cure for 18-24 hours at ambient
temperature, then oven dry for 4 hours at 82°C (180°F) and
for an additional 4 hours at 104°C (220°F). This helps to
prevent flaking and chipping.

A 10% caustic or alkaline solution such as 10% NaOH
(Sodium Hydroxide) will break down the OB-400 after it
has cured. However, care should be exercised as far as
the compatibility of the caustic solution with any other
components involved in the application, such as the material
or surface that the cured cement has been applied to.

DIRECTIONS FOR USE
NOTE
OMEGABOND® OB-400 Cement is a one-part cement and
is supplied as a powder, Just mix the powder with water to
a smooth, uniform consistency. Avoid using excess liquids
as this will reduce mechanical strength, increase shrinkage
and delay the set time. Surfaces to which the cement will
