Technical Data April, 2016
Product
Description 3M Scotch-WeldPlastic 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 achieved on materials such as heavily plasticized PVC, EPDM,
ABS, Nylon, Santoprene®
, and Viton®
.
Specific Features 3M Scotch-WeldPlastic and Rubber Instant Adhesive PR40 is a low viscosity
cyanoacrylate adhesive which bonds close-fitting plastic or rubber parts quickly and
with high strength.
3M Scotch-WeldPlastic and Rubber Instant Adhesive PR100 is a general
purpose, low viscosity bonder for rubber or plastic surfaces.
3M Scotch-WeldPlastic 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.
3M™ Scotch-Weld™ Plastic and Rubber Instant Adhesive PR1500 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.
3M Scotch-WeldPlastic and Rubber Instant Adhesive PR Gel 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.

Handling Information 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. An 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 down the cure rate.
3. After curing, 3M Scotch-WeldPlastic and Rubber Instant Adhesive bonds
are suitable for use up to about 180°F (82°C).
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 manufacturers precautions and directions for use.

Storage For short term storage (<30 days), keep adhesive in a cool (60°F to 80°F [16°C to
27°C]), dry place out of direct sunlight. Keep containers tightly covered and free of
moisture. Refrigeration (40°F [4°C]) gives optimum long term storage stability.
