Request Information
3M™ Surface Pre-Treatment AC-130 is high performance surface preparations for adhesive bonding. As sol-gel preparations, 3M™ AC-130 Pre-Treatment products promote enhanced adhesion as a result of the chemical interaction at the interfaces between the metal and the 3M™ AC-130 Pre-Treatment (sol-gel) and the 3M™ AC-130 Pre-Treatment and the primer.

Common surface preparation techniques such as phosphoric acid anodizing (PAA) or sulfuric acid-sodium dichromate etchings are used to provide acceptable surfaces for bonding. These hazardous materials and waste produced by these procedures are both environmentally and economically undesirable. 3M™ AC-130 Pre-Treatment provides an excellent environmentally friendly alternative to achieve the high performance required.

Surface Preparation

Surface Preparation

 N/A 3M™ Surface Pre-Treatment AC-130 may be applied to surfaces after manually deoxidizing the surface by either
  1. Grit blasting;
  2. Sanding with #180 or finer sandpaper, or
  3. Scotch-Brite™ pad abrasion.
The success of the bonding operation relies on the thorough de-oxidation and preparation of the metal surface.

Typical Application Technique

Typical Application Technique

 N/A Prepare 3M™ Surface Pre-Treatment AC-130 in accordance with instructions. Scale up for size of part and the method of spray application as necessary. Application rate is approximately 1 liter of 3M™ AC-130 Pre-Treatment per 50 square feet of surface to be coated.

Spray Application

Spray Application

 N/A Apply 3M™ Surface Pre-Treatment AC-130 coating solution by spray-drenching the part surface. Spray solution generously, allowing excess to run off of the part surface. Keep part surface continuously wet with the solution for a minimum of 1 minute. Part surfaces must not be allowed to dry and should be drenched with fresh solution at least 1 time during the application period. Ensure treated surface does not dry between spray coats. Larger surface areas may require being coated in sections.

Allow coated part to drain for 5 to 10 minutes. If there is any surplus 3M™ AC-130 Pre-Treatment that has pooled or collected in crevices, pockets, or other collection areas, including drip edges or fastener holes, use filtered compressed air to blow off excess solution while maintaining a wet surface. Do not splatter this excess solution onto adjoining part surfaces. A cloth prewetted with 3M™ AC-130 Pre-Treatment may be used to gently blot, not rub, the surface of pooled solution. Do not blow dry areas of the part that are able to freely drain.

Brush Application

Brush Application

 N/A Apply fresh 3M™ Surface Pre-Treatment AC-130 liberally by brushing with a clean natural bristle brush or swabbing with a clean wiper, cheesecloth or gauze. Do not scrub with a brush or applicator. Apply solution generously, keeping the part surface continuously wet with the solution for a minimum period of 1 minute. Part surface should be drenched with solution. Brushes or wipers should not leave streaks on the surface. Part surfaces must not be allowed to dry and should be wetted with fresh solution at least one time during the solution application process.

Allow coated part to drain for 5 to 10 minutes. If there is any surplus 3M™ AC-130 Pre-Treatment that has pooled or collected in crevices, pockets, or other collection areas, including drip edges or fastener holes, use filtered compressed air to blow off excess solution while maintaining a wet surface. Do not splatter this excess solution onto adjoining part surfaces. A cloth prewetted with 3M™ AC-130 Pre-Treatment may be used to gently blot, not rub, the surface of pooled solution. Do not blow dry areas of the part that are able to freely drain.

Dry/Cure of 3M™ Surface Pre-Treatment

Dry/Cure of 3M™ Surface Pre-Treatment

 N/A Dry the solution-coated parts under ambient conditions for a minimum of 60 minutes. Minimize contact with the part, as the coating may be easily damaged or contaminated until fully cured. Exact drying time will vary depending on configuration of the part and ambient conditions. Alternately, after drying at ambient temperature for a minimum of 30 minutes parts may be heated to 140 ºF maximum for an additional 30 minutes minimum to facilitate drying. After drying, coated surfaces should be protected from contamination prior to applying the bonding primer.

Health and Safety Precaution

Additional Information

Additional Information

 N/A When used with the leading adhesive primers and adhesives, 3M™ AC-130 Pre-Treatment provides an economical and environmentally superior alternative to more costly and hazardous processes. The product may be applied by brush, spray, or dip. Simply, 3M™ AC-130 Pre-Treatment is applied to surfaces at ambient drying conditions and then primed prior to bonding.

Long-term durability of adhesion to metal has been demonstrated. Data reveals 3M™ AC-130 Pre-Treatment provides equivalent or better moisture durability than many of the currently used surface preparations for on-aircraft repairs.

Testing by the wedge test described in ASTM D3762 on aluminum substrates shows that 3M™ AC-130 Pre-Treatment performs comparatively to the more traditional grit-blast silane procedure. When grit-blast is used with the 3M™ AC-130 Pre- Treatment, the sol-gel process has shown wedge test results similar to PAA (Phosphoric Acid Anodizing). The grit-blast and 3M™ AC-130 Pre-Treatment process also provided acceptable test results on titanium, stainless steel, and nickel alloys in the same test compared to standard controls.

3M™ AC-130 Pre-Treatment also performs similarly to PAA in tensile lap shear and floating roller peel tests at a variety of temperatures. The grit-blast process has been shown to provide a more durable bond than the nylon pad process in the wedge test at 60 ºC and 95-100 % RH. However, the nylon pad process provides end-users with a process that exceeds the performance of the grit-blast silane surface preparation, is quicker to perform in the field, and does not require the painstaking containment and subsequent cleaning of residual grit.
