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.”
IMPORTANT MIXING DIRECTION:
It is important to remix the B component thoroughly prior to combining with the A side.
CURE SCHEDULE/HEAT CURING:
Most of the physical properties can be achieved in 5-7 days at 77 F (25 C). You may use your own post-cure schedule but the physical
properties may vary from BJB s cure schedule of 1-3 hours at 77 F (25 C) followed by 16 hours at 160 F (71 C). Do not exceed
curing temperature of 200 F (93 C). Support of the part may be required to prevent part deformation during the heat curing process.
COLOR VARIATIONS:
The color of the base material may vary slightly from batch to batch due to raw ingredients. Color variations will not affect the
cured physical properties. Exposing the material to various conditions such as heat and UV light will alter the color of the cured
system. Color stability is not guaranteed. This product can be pigmented, but you may see more color shift when using lighter
pigments.
UV RESISTANCE:
This product is not classified as UV resistant. BJB offers an additive called UV-100, a UV inhibitor and anti-oxidant blend that
will help slow down the effects of UV degradation and color change. The level of effectiveness varies from product to product.
ACCESSORIES:
BJB offers silicone RTV mold making materials along with a wide range of accessory items. These include de-airing agents, pigments,
mold releases, and Jiffy Mixers. Visit BJB s website at www.bjbenterprises.com or consult a BJB representative for more
information.
STORAGE:
Store at ambient temperatures, 65-80 F (18-27 C). Unopened containers will have a shelf life of 6 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. Repeat 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.
