Directions for Use

Surface Preparation:

Surfaces to be sealed or bonded should be clean and dry. Surfaces should be free from

grease, mold release, oil, water/condensation, and other contaminants that may affect

the adhesion of the sealant. Abrading with 180 to 220 grit abrasive followed by a

solvent wipe will improve the bond strength. Suitable solvents include 3M™ Adhesive

Remover, methyl ethyl ketone (MEK), isopropyl alcohol (IPA), or acetone.*

*When using solvents, use in a well ventilated area. Extinguish all sources of ignition in

the work area and observe product directions for use and precautionary measures.

Refer to product label and MSDS for further precautions. Always pre-test solvent to

ensure it is compatible with substrates.

Local and federal air quality regulations may regulate or prohibit the use of these

products or surface preparation and cleanup materials. Consult local and federal air

quality regulations before using these products.

Primer:

Use of a primer is an extra step and cost and will depend on substrates and the final

end use. Using primer can improve the corrosion resistance of certain metals as well

as improve the durability of the bond when exposed to high humidity conditions.

For most applications, high strength bonds on metal can be achieved without the use

of a primer. Pre-testing for adhesion is suggested to determine if a primer is needed.

Contact your 3M Technical Service representative for primer recommendation and

application advice.

Application:

Loading the applicator gun: make sure the applicator is set up with correct

plunger attachment for cartridge or sausage pack.

Metal Cartridge: Puncture seal in nozzle and remove the pull-tab seal at the

bottom of the cartridge. Load into applicator and fix retaining ring (if applicable).

Assemble the nozzle (if applicable) and cut to desired size and shape.

Plastic Cartridge: Cut off the top of the cartridge with a sharp blade, just above the

area where the threads stop. Attach the nozzle and cut to desired size and shape.

Sausage Pack: Make a 1" slit close to the crimp on one end of the sausage pack.

Load the sausage pack into the applicator barrel (slit side out). Place the rounded

end of the supplied sausage nozzle onto the slit end of the sausage pack and fix

with retaining ring. Cut nozzle to desired size and shape.

Product should be used within 24 hours after seal is punctured. Dispense product

with the nozzle tip in contact with the substrate to insure good gap filling and

substrate wetting. Bonding must occur within the first 50% of published skin time

Do not apply SMP sealants and adhesive sealants on frozen nor wet surfaces.

Do not apply over silicone nor in the presence of curing silicone or curing

polyurethane. Avoid contact with uncured polyurethane during curing. Sealant can

be tooled immediately after applying to give desired appearance.

Cleanup:

While sealant is still soft, cleaning can be done with the same solvents used for surface

preparation. If sealant is already cured, removal is done mechanically with razor knife,

piano wire, sanding or 3M™ Scotch-Brite™ Molding Adhesive and Stripe Removal

Disc. This disc is available from 3M Automotive Aftermarket Division.
