TC-5015 A/B
TRANSLUCENT SILICONE RUBBER
TC-5015 A/B is a room temperature, addition/platinum curing silicone rubber designed for making molds and parts. When
used to make molds, the TC-5015 A/B is translucent enough to see through when casting into the mold cavity. This aids in
developing void free surfaces on the casting. TC-5015 A/B is also commonly used to make ink stamp pads as well as other
types of pressure pads.

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-5015A/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.

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. 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
as directed by medical personnel. Never give anything by mouth to an unconscious person.
Refer to the Material Safety Data Sheet before using this product.
