Product
Description 3M™ Scotch-Weld™ Plastic and Rubber Instant Adhesives are designed to give
exceptional performance on difficult-to-bond plastic and rubber substrates. These adhesives
may be bonded to like substrates or in combination with metal or composite substrates.
Superior performance is achie ved on materials such as heavily plasticized PVC, EPDM,
ABS, Nylon, Santoprene®
, and Viton®
.
Technical Data March, 2010
Specific Features 3M™ Scotch-Weld Plastic and Rubber Instant Adhesive PR5 is a very low viscosity,
high-speed bonding cyanoacrylate formulated for plastics and rubbers. It is
recommended for use on assemblies with very close-fitting parts and smooth, even
surfaces. It can be used to wick into bonding gaps of assembled parts.
3M™ Scotch-Weld™ Plastic and Rubber Instant Adhesive PR40 is a low viscosity
cyanoacrylate adhesi ve which bonds close-fitting plastic or rubber parts quickly and with
high strength.
3M™ Scotch-Weld Plastic and Rubber Instant Adhesi ve PR100 (formerly SB04 or
SB14) is a general purpose, low viscosity bonder for rubber or plastic surfaces. It has
been tested and passed the requirements of Commercial Item Description A-A-3097,
Type II, Class 2 (formerly MIL-A-46050C).
3M™ Scotch-Weld™ Plastic and Rubber Instant Adhesive PR600 is a medium viscosity
cyanoacrylate with some gap-filling capability. It will bond many common substrates
including plastics and rubbers. It has been tested and passed the requirements of
Commercial Item Description A-A-3097, Type II, Class 3 (formerly MIL-A-46050C).
3M™ Scotch-Weld™ Plastic and Rubber Instant Adhesive PR600B is a black version of
3M™ Scotch-Weld™ Plastic and Rubber Instant Adhesive PR600.
3M™ Scotch-Weld™ Plastic and Rubber Instant Adhesive PR1500 (formerly SB16) is
a high viscosity cyanoacrylate that can be used on plastic or rubber parts that do not fit
well together. It has excellent gap-filling characteristics and will not wick into
unwanted areas. It has been tested and passed the requirements of Commercial Item
Description A-A-3097, Type II, Class 3 (formerly MIL-A-46050C).
3M™ Scotch-Weld Plastic and Rubber Instant Adhesi ve PR Gel (formerly PR54) is a
fast curing, very high viscosity, gap-filling cyanoacrylate. Its gel formulation is suitable
for bonding poorly mating components and for porous substrates and can be used on
vertical surfaces as it will not drip or slump.

Surface Preparation
For optimum strength structural bonds, paint, oxide films, oils, dust, mold release
agents, and all other surface contaminants must be completely removed. However,
the amount of surface preparation depends on the required bond strength and the
environmental aging resistance desired by the user. Typical quick surface preparation
would include wiping with a clean solvent (such as isopropyl alcohol*), abrading
the surface with a clean fine abrasive, and then wiping again with a clean solvent to
remove loose particles.
Directions for Use
1. Ensure that parts are clean, dry, and free from oil and grease.
2. A instant adhesive activator may be required if there are bonding gaps or
porous substrate surfaces, if substrates are low surface energy plastics
(e.g., polyethylene, polypropylene) or if substrates have acidic surfaces
(e.g., paper, leather).
3. Bond speed is typically very fast so ensure that parts are properly aligned before
dispensing.
4. Product is normally hand applied from the bottle. Apply sparingly to one surface
and press parts firmly together until handling strength is achieved. As a general
rule, as little cyanoacrylate as possible should be used. Over application will
result in slower cure speed and lower bond strength.
Cured Bond Characteristics
1. Full bond strength will typically be achieved within a 24 hour cure time.
2. Low humidity or low temperature conditions will slow do wn the cure rate.
3. After curing, 3M Scotch-Weld™ Plastic and Rubber Instant Adhesiv e bonds
are suitable for use up to about 180°F (82°C). At 180°F (82°C) the bonds will
be approximately 70% of the strength at room temperature and at 212°F
(100°C) about 50% of full strength.
4. Cyanoacrylate bond resistance to most oils and solvents is excellent. Long term
humidity, moisture, or water immersion may affect the strength of a cured
cyanoacrylate bond depending on the substrates and the bond gap. Testing is
recommended to evaluate the effect.
*Note: When using solvents, extinguish all ignition sources, including pilot lights,
and follow the manufacturer’s precautions and directions for use.
Handling Information
Storage For short term storage (<30 days), k eep adhesive in a cool (60°F to 80°F [16°C to
27°C]), dry place out of direct sunlight. K eep containers tightly covered and free of
moisture. Refrigeration (40°F [4°C]) gi ves optimum long term storage stability.
Shelf Life 3M™ Scotch-Weld™ Plastic and Rubber Instant Adhesi ves can be expected to have
a shelf life of one year from the date of shipment from 3M when stored under
refrigerated conditions.
