3M Adhesion Promoter 111

Surface Preparation

Surface must be clean, dry, and free of wax, oil, grease and loose particles.

Substrate must be unified.

Contaminated surfaces must be cleaned with an appropriate cleaner and/or a 50/50 mixture of isopropyl alcohol and water.

When using solvents, extinguish all ignition sources, including pilot lights, and follow the manufacturer’s precautions and directions for use.

Application

Apply a thin, uniform coating to the bonding surface before application of 3M™ VHB™ Tape. Use the minimum amount that will fully coat the area to be taped.

Application may be done with a clean lint-free cloth, pad, felt tipped dauber, absorbent paper towel or disposable tissue. Brushes, rollers, or spraying tend to apply excessive amounts of 3M™ Adhesion Promoter 111 and should therefore be avoided.

Apply tape within 8 hours, or reapply 3M adhesion promoter 111.

Curing

Allow to dry completely prior to application of tape. Depending on temperature and humidity, the drying and reacting time of 3M adhesion promoter 111 can vary. Typical drying time will be 1-2 minutes. Forced, hot air drying of 3M adhesion promoter 111 is acceptable, but remember that 3M adhesion promoter 111 is flammable and must not be used near any open flames or ignition sources

Clean-Up

3M™ Adhesion Promoter 111 can be removed from unwanted surfaces with straight isopropyl alcohol (IPA) or a blend of IPA and water. Rubbing Alcohol is typically 70% IPA and 30% water.

Excessive 3M adhesion promoter 111 may cause a dull white appearance on the surface. A small amount of chalking should not adversely affect the adhesive strength. If desired, for appearance purposes, the dull white chalking may be removed after tape application with either a clean dry cloth or a clean cloth that is slightly wet with isopropyl alcohol. Before tape application, the dull white chalking may be removed with a clean cloth that is only slightly wet with more 3M adhesion promoter 111.

When using solvents, extinguish all ignition sources, including pilot lights, and follow the manufacturer’s precautions and directions for use.
