TC-5140 A/B
40 SHORE A TRANSLUCENT SILICONE RUBBER

TC-5140 A/B is a room temperature, addition/platinum curing silicone rubber designed for making molds and parts. Featuring
exceptional tear strength, low viscosity, 1:1 mix ratio, and a quick demold time, this system is user friendly while producing
high quality finished products. When used to make molds, the TC-5140 A/B is translucent enough to see through when casting
into the mold cavity. For making parts, this system is easily pigmented with BJB s 8100 Series Silicone Pigments.

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 include condensation/tin cured
based silicone, lacquer and enamel coatings, polyester-based products, copper or copper containing metals, some SLA 3D
Printing resins, and natural rubbers like latex. Inhibition may easily be determined by brushing a small quantity of TC-5140
A/B over a localized area of the surface to be reproduced. If the TC-5140 A/B is tacky or uncured after the cure time, then you
know the mold surface is acting as an inhibitor. To insure against possible problems, it is advisable to spray a barrier film over
any questionable surfaces. This is the best way of treating clays and other surfaces that cause inhibition. Contact BJB for
recommended products.

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.

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. Solvents 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

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.

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.

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.

INHIBITION:

Certain materials will cause inhibition or neutralization of the curing agent. These materials include condensation/tin cured
based silicone, lacquer and enamel coatings, polyester-based products, copper or copper containing metals, some SLA resins,
and natural rubbers like latex. Inhibition may easily be determined by brushing a small quantity of TC-5030 A/B over a
localized area of the surface to be reproduced. If the TC-5030 A/B is tacky or uncured after the cure time, then you know the
mold surface is acting as an inhibitor. Molds made from wood, plaster, steel, aluminum, or plastic should not cause inhibition
if they are clean. To insure against possible problems, it is advisable to spray a barrier film over any questionable surfaces.
This is the best way of treating clays and other surfaces that cause inhibition. Contact BJB for recommended products.

MIXING:

TC-5024 A/B is processed by adding curing agent “B” at a ratio of 10 parts by weight to 100 parts by weight of “A”. TC-5024
“B” side is tinted blue so that when mixing the “A” and “B” sides together, the colorant in the “B” side will provide a visible
means of insuring that a uniform mix is acquired. Mix for 2 to 3 minutes in a clean container, then transfer material to another
clean container and mix for another 2 to 3 minutes.

INHIBITION:

New molds made with tin catalyzed silicones often have a tendency to inhibit the cure of softer elastomeric and aliphatic
urethanes (Water Clear Series) that are cast against the silicone. Post curing a new mold at 150 F for 24 hours may reduce the
cure inhibition problem in most cases. It is also recommended that the mold surface be washed thoroughly with soap and warm
water then dried before use.

STORAGE:

Store ambient temperatures, 65-80 F (18-27 C). Unopened containers will have a shelf life of 12 months from date of
