BJB s MD Series of semi rigid, medium work time urethane elastomers exhibit great flexibility and excellent durability. These
tough, abrasion resistant systems easily process at room temperature. The MD Series is perfect for larger or more complex parts
and offers superior performance in many applications such as rollers, foundry tooling and high impact semi rigid parts. For faster
work times consider BJB s FD Series of elastomers.

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.”
NOTE:
Cure times are subject to part size. Smaller parts may need additional time in the mold or add mild heat (100-120 F) to decrease
demold time. Heat will also increase toughness of parts upon demold.
Prolonged direct exposure to sunlight can affect the surface of this product. Cover molds or other products when storing outdoors
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).
PREPARATION AND RELEASING:
When MD-70 REV 1 A/B is used to produce molds or parts from plaster, wood or other porous substrates, we would first recommend
that they be sealed. Release agents may then be applied over the sealed surface.
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 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. 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.
WARNING: This product can expose you to chemicals including Toluene diisocyanate, which are known to the State of

PREPARATION AND RELEASING:
When M-3195 REV 1 A/B is used to produce molds or parts from plaster, wood or other porous substrates, we would first recommend that
they be sealed. Release agents may then be applied over the sealed surface.
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.

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.
WARNING: This product can expose you to chemicals including Toluene diisocyanate, which are known to the State of California to
cause cancer. For more information, go to www.P65Warnings.ca.gov.

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.”
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).
PREPARATION AND RELEASING:
When M-3195 REV 1 A/B is used to produce molds or parts from plaster, wood or other porous substrates, we would first recommend that
they be sealed. Release agents may then be applied over the sealed surface.
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.
NOTE:
Prolonged direct exposure to sunlight can affect the surface of this product. Cover molds or other products when storing outdoors.
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 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. 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.
