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.
