| Plexus PC-120 is a low-viscosity liquid designed to be applied to aluminum and stainless steel parts prior to bonding with Plexus adhesives. Excess oils or contaminants should be wiped from the surface with a clean cloth. The cleaner/conditioner should be applied in a thin layer. The usual application techniques are wiping, brushing, or spraying. Allow the PC-120 to dry slightly before wiping away. PC-120 contains a red dye to assist with proper application. When a light red tint is seen on the assembly enough cleaner/conditioner has been applied. An even amount of cleaner/conditioner across the area to be bonded is recommended. Allow the PC-120 to dry before applying adhesive. Although Plexus PC-120 is often called a primer, it is not one in the sense that a large coating should be applied to the metal surface. Using PC-120 as a cleaner/conditioner will leave sufficient active ingredienton the metal surface to provide for enhanced protection. Excess amounts appearing in a deep red and heavy coating may produce opposite effects and weaken bonds. Plexus® Cleaner Conditioner PC-120 is a chemical cleaner and conditioner designed to improve the long-term bonddurability of Plexus adhesives when used for adhering aluminum and stainless steel assemblies. Fast drying at ambient temperatures, parts can be bonded 1 to 3 minutes after the conditioner is applied. Typically, water and salt can attack bonded metal structures at the adhesive interface, potentially reducing the overall strength. The active ingredients in this cleaner allow the adhesive to produce a bond which can resist long term exposure to salt water. Plexus PC-120 acts as a cleaner to remove contaminants on the metal surface. In many circumstances, the use of PC120 can replace routine solvent cleaning. Application can be performed by brushing or wiping. Allow the PC-120 to dry slightly before wiping away. Only a thin film of PC-120 is needed. The cleaner/conditioner contains a red dye. As long as a red tint is slightly visible on the metal surfaces, sufficient conditioner has been applied. Once the conditioner is dry, the parts are ready to bond. Benefits: • Improves long term bond • Durability of Aluminum or Stainless Steel bonds • Fast Drying • Cleans metal surfaces prior to bonding. Color: translucent red dye. Carrier solvent is isopropyl alcohol. Information provided by ITW Performance Polymers. |
