Substrates

•

Personal protective gear (safety glasses, powder-free gloves,

etc) Clean entire surface of substrates using a solvent or non-

greasy cleaner.

Apply 3M™ Adhesion Promoter AP596 to both substrates: Pour 3M AP596 Adhesion Promoter onto a soft

lint-free cloth folded in quarters. Wipe the bonding area, flipping the cloth at regular intervals to reveal a clean

section. With a new clean folded cloth, wipe off the 3M AP596 Adhesion Promoter in the same manner,

flipping the cloth at regular intervals to reveal a clean section. Wait 15 minutes to dry.

Apply appropriate 3M™ Primer to both substrates: Shake appropriate 3M Primer for 30 seconds after you

hear the ball moving inside the bottle. Dip a clean wool dauber into the primer. Roll the dauber around the

edge of the bottle to squeeze out excess primer. Replace cover on primer bottle. Apply a single continuous

layer of primer to the surface. Wait 30 minutes to dry.

Refer to the Instructions for Use for the appropriate adhesive/sealant chosen and proceed accordingly.

Cleanup: Use a solvent such as MEK to clean up any excess primer.

Application Equipment

for 3M™ Primer

Wool dauber is recommended for applying 3M Primers. Use of a paint brush or other

method of application is not recommended because there will be voids in the coating

after application. Any voids will cause a defect in the coating and will affect bond

quality. Contact your 3M Sales Representative for information on ordering Wool

Daubers.

Storage

3M™ Adhesion Promoter AP596 and 3M™ Primers P591 and P592 must be stored

in an appropriate climate controlled space suitable for

flammable materials. Store the products in the original unopened containers below

77°F (25°C) to maximize shelf life.

Shelf Life

When stored at recommended conditions, the shelf life is 12 months from the date of

manufacture. After opening, the 3M AP596 Adhesion Promoter must be used within

30 days (if the product begins to turn cloudy, dispose of properly). After opening

the 3M Primers P591 and P592, they must be used within 7 days (the viscosity will

increase with each exposure to air).
