M-3130 A/B
30 SHORE A POLYURETHANE ELASTOMER
BJB s M Series with work times between 10 and 20 minutes is perfect for a variety of part and mold applications. These
flexible systems exhibit exceptional physical properties. M-3130 is ideal for processing by hand or cartridge-dispensing with our
CPE handheld dispense equipment. For faster work time see our F-1 Series and for longer work times see the L Series of urethane
elastomers.

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 M-3130 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.
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.
