ASI 70
Silicone Compound
DESCRIPTION
ASI 70 Silicone
Compound is a moisture-resistant, translucent, non-curing paste that
retains its consistency and properties over a temperature range of
-50°C to 200°C (-55°F to 390°F). Essentially non-toxic and non-melting,
ASI 70 has excellent dielectric properties, is highly water repellent
and resistant to oxidation. Practically non-volatile, ASI 70 is also
odorless and resistant to a wide range of chemicals.
TYPICAL USES
ASI 70 Compound
is typically used where a silicone fluid would tend to migrate. The
compound retains its paste-like consistency and will not soften or
flow. There are a variety of applications requiring the unique combination
of ASI 70 properties including moisture resistance, high dielectric,
lubricity and release characteristics. Such applications include:
mold release agent for foundry shell and core
molds
release agent for plastic extruders and processing
equipment
break-in treatment for bladders on tire presses
mold release agent for plastic and rubber
parts
disconnect junctions in electrical wiring
systems
moisture-proof seal for ignition systems and
spark plug connections
corrosion protection for copper conductors,
battery terminals and device leads
cable pulling lubricant to draw rubber-covered
cable through conduit
lubricant for cable connectors, rubber door
seals, switches and rubber/plastic O-rings
mild chemical barrier coating
DIRECTIONS
ASI 70 can be
easily applied by brushing or wiping. For thin coatings, ASI 70 can
be applied as a solvent dispersion by brushing, dipping or spraying.
Suitable solvents include toluol, naphtha or chlorinated solvent.
If a thinner consistency compound is required for applications where
brushing, dipping or wiping is desirable, contact your ASI representative.
ASI 70 should not be applied to any surface that will subsequently
be painted or finished. Such coatings might not adhere to the silicone-treated
surfaces. Contaminated parts can be wiped or washed with solvent,
washed with detergent and then rinsed in clear water before painting.
For more specific information regarding the removal of a silicone
com-pound please contact manufacturer.
SOLUBILITY
ASI 70 is insoluble
in water, alcohols and mineral oil. It is partially soluble in ketones,
ether, esters, chlorinated solvents and hydrocarbons. The suitability
of a particular solvent should be based on testing prior to use. Flammability
and toxicological properties should be considered in the choice.
CHEMICAL RESISTANCE
ASI 70 is generally
not affected by mineral and vegetable oils or air and generally resistant
to dilute acids and alkalies and to most aqueous solutions. ASI 70
should not be used with liquid oxygen or in applications requiring
LOX compatibility. FDA STATUS ASI 70 is permitted under regulations
of the Food and Drug Administration where incidental food contact
might be involved. FDA Regulation number is 175.300.
PACKAGING
ASI 70 is supplied
in- (2.7 fl. oz. and 5.3 fl. oz.) squeeze tubes.
STORAGE
ASI 70 has a
shelf life of 12 months from date of shipment.
SAFETY PRECAUTIONS
ASI 70 might
cause slight temporary discomfort if accidentally rubbed into eyes.
It is essentially non-irritating to the skin.
WARRANTY
ASI warrants only that its products
will meet its specifications. ASI shall in no event be liable for
incidental or consequential damages. Except as expressly stipulated,
ASI’s liability, expressed or implied, is limited to the stated selling
