Product Description

3M™ Scotch-Weld™ Instant Adhesive Activators and Primers are

liquid chemical products used in conjunction with 3M™ Scotch-Weld™ Instant

Adhesives. 3M™ Scotch-Weld™ Instant Adhesive Activators AC09, AC11,

AC113, and AC452 are activators that promote very fast curing that may be

useful for the fast cure of thick bond lines and in bonding situations where the

absorption of a lower viscosity cyanoacrylate into a porous substrate needs to be

curtailed. These activators may also be used to “fillet-cure” Scotch-Weld

cyanoacrylates and to cure adhesives outside the joint. They primarily differ in

their solvent base.

Scotch-Weld™ AC77 is a cyanoacrylate primer that aids bonding to low surface

energy plastic substrates. Scotch-Weld™ AC79 is cyanoacrylate primer for

elastomeric substrates.

Note: These products should be tested on substrates before use since their

overspray or excess may attack certain substrates (especially some plastics)

causing unsightly effects.

Specific Features

• 3M™ Scotch-Weld™ Instant Adhesive Activator AC09 is a fluorinated solvent

based activator that is non-flammable.

• 3M™ Scotch-Weld™ Instant Adhesive Activator AC11 is a solvent based

activator that is especially suitable for use with slower curing, high viscosity

grades and with porous substrates where the adhesive must cure before being

absorbed into the substrate

• 3M™ Scotch-Weld™ Instant Adhesive Activator AC113 is heptane based

activator. This activator will not attack plastics.

• 3M™ Scotch-Weld™ Instant Adhesive Activator AC452 is an acetone based

activator that may attack some plastics.

• 3M™ Scotch-Weld™ Instant Adhesive Primer AC77 is designed for difficult-to

bond, low surface energy plastics such as polypropylene, polyethylene, and

PTFE. This primer needs to be applied to each low surface energy substrate

surface.

• 3M™ Scotch-Weld™ Instant Adhesive Primer AC79 helps to bind elastomeric

materials including silicone.
