TC-5060 A/B
60 SHORE A
ROOM TEMPERATURE CURING SILICONE
TC-5060 A/B is a room temperature, addition/platinum curing silicone rubber designed for:
Mold making Encapsulation applications Pressure pads
Gaskets Casting low-melt metals into Various types of parts
With the use of talc powder as an interface the TC-5060 has been used with cast metal temperatures running 650 F (344 C) and
has been subject to temperatures up to 850 F (454 C) for making a limited number of casts. With the ability to withstand high
temperatures the TC-5060 works very well as a mask for metal spraying and welding operations.

NON-WARRANTY “Except for a warranty that materials substantially comply with the data presented in Manufacturer’s latest bulletin describing the product (the basis for this substantial
compliance is to be determined by the standard quality control tests generally performed by Manufacturer), all materials are sold “AS IS” and without any warranty express or implied as
to merchantability, fitness for a particular purpose, patent, trademark or copyright infringement, or as to any other matter. In no event shall Manufacturer’s liability for damages exceed
Manufacturer’s sale price of the particular quantity with respect to which damages are claimed.”
INHIBITION:
Certain materials will cause inhibition or neutralization of the curing agent. These materials are sulphur containing and
organometallic salt containing compounds such as organic rubbers and many condensation cured RTV silicone rubbers.
Inhibition may easily be determined by brushing a small quantity of TC-5060 over a localized area of the surface to be
reproduced. If the TC-5060 is gummy or uncured after the curing time, then you know the mold surface is acting as an inhibitor.
Molds made from wood, plaster, metal or plastic should not cause inhibition if they are clean. To insure against possible
problems, it is advisable to spray a barrier film (BJB product RF-5215) over any questionable surfaces. This is the best way of
treating clays and surfaces that cause inhibition.
STORAGE:
Store in a cool dry place. Unopened containers will have a shelf life of 12 months from date of shipment when properly stored
at room temperatures. Purge opened containers with dry nitrogen before re-sealing.

Although TC-5045 A/B has proven to be less inhibited in curing against most substrates some materials may cause inhibition or
neutralization of the curing agent. Inhibition may easily be determined by brushing a small quantity of TC-5045 A/B over a
localized area of the surface to be reproduced. If the TC-5045 A/B is gummy or uncured after the curing time, then you know
the mold surface is acting as an inhibitor. Molds made from wood, plaster, metal or plastic should not cause inhibition if they are
clean. To insure against possible problems, it is advisable to spray a RF barrier film (BJB product RF-5215) over any
questionable surfaces. This is the best way of treating clays and surfaces that cause inhibition.
STORAGE:
Store ambient temperatures, 65-80 F (18-27 C). Unopened containers will have a shelf life of 12 months from date of
shipment when properly stored at recommended temperatures. Purge opened containers with dry nitrogen before re-sealing.

SAFETY PRECAUTIONS:
Use in a well-ventilated area. Avoid contact with skin using protective gloves and protective clothing. Repeated or prolonged
contact on the skin may cause an allergic reaction.
Eye protection is extremely important. Always use approved safety glasses or goggles when handling this product.
IF CONTACT OCCURS:
Skin: Immediately wash with soap and water. Remove contaminated clothing and launder before reuse. It is not
recommended to remove resin from skin with solvents. Solvent only increase contact and dry skin. Seek
qualified medical attention if allergic reactions occur.
Eyes: Immediately flush with water for at least 15 minutes. Call a physician.
Ingestion: If swallowed, call a physician immediately. Remove stomach contents by gastric suction or induce vomiting only
as directed by medical personnel. Never give anything by mouth to an unconscious person.

TC-5041 A/B
40 SHORE A
ROOM TEMPERATURE CURING SILICONE
TC-5041 A/B is a high tear strength, addition/platinum, room temperature curing silicone rubber designed for mold making,
encapsulation applications, pressure pads, gaskets, and various types of parts. It is also used to make molds for casting low
melting metals. With the use of talc powder as an interface the TC-5041 A/B has been used with cast metal temperatures
running 650 F (344 C). With the ability to withstand high temperatures the TC-5041 A/B works very well as a mask for metal
spraying and welding operations.

NON-WARRANTY “Except for a warranty that materials substantially comply with the data presented in Manufacturer’s latest bulletin describing the product (the basis for this substantial
compliance is to be determined by the standard quality control tests generally performed by Manufacturer), all materials are sold “AS IS” and without any warranty express or implied as
to merchantability, fitness for a particular purpose, patent, trademark or copyright infringement, or as to any other matter. In no event shall Manufacturer’s liability for damages exceed
Manufacturer’s sale price of the particular quantity with respect to which damages are claimed.”
INHIBITION:
Certain materials will cause inhibition or neutralization of the curing agent. These materials are sulphur containing and
organometallic salt containing compounds such as organic rubbers and many condensation cured RTV silicone rubbers.
Inhibition may easily be determined by brushing a small quantity of TC-5041 over a localized area of the surface to be
reproduced. If the TC-5041 is gummy or uncured after the curing time, then you know the mold surface is acting as an inhibitor.
Molds made from wood, plaster, metal or plastic should not cause inhibition if they are clean. To insure against possible
problems, it is advisable to seal the surface with RF-5215 or other appropriate sealer. Contact BJB s Tech Sales for additional
information.
