3M™ Surface Pre-Treatment AC-130 and AC-130-2 are 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.
