Installation Guide
Step 1: Surface Cleaning
- Clean the bonding surface to remove dust, oil, grease, and contaminants.
- Ensure the surface is completely dry before application.
Step 2: Apply Adhesion Promoter
- Apply a thin and uniform layer of 3M AC-160 to the bonding area.
- Avoid excessive coating, which may reduce adhesive effectiveness.
Step 3: Allow Surface Drying
- Allow the treated surface to dry completely.
- Drying time depends on temperature, humidity, and coating thickness.
Step 4: Apply Adhesive Tape
- Apply the tape firmly with consistent pressure.
- Ensure complete contact between tape adhesive and treated surface.
Step 5: Bond Conditioning
- Allow adequate time for maximum bond strength development before applying heavy loads.
Storage
- Keep container tightly sealed when not in use.
- Store in a cool, dry environment.
- Avoid direct sunlight and extreme temperatures.
- Store in the original packaging.
- Follow recommended shelf-life conditions.
FAQ
Q1: What is 3M Adhesion Promoter AC-160 used for?
3M AC-160 is used to improve the adhesion performance of industrial adhesive tapes on challenging substrates.
Q2: Can AC-160 be used with 3M VHB tapes?
Yes. Adhesion promoters are commonly used with acrylic foam tapes such as 3M VHB products when bonding to difficult surfaces.
Q3: What surfaces require an adhesion promoter?
Low surface energy plastics, painted surfaces, powder-coated materials, and other difficult substrates may benefit from AC-160 treatment.
Q4: How long should AC-160 dry before tape application?
Drying time depends on environmental conditions. The treated surface should be completely dry before applying adhesive tape.
Q5: Does AC-160 replace surface cleaning?
No. Proper cleaning and surface preparation are still required before applying adhesion promoter.
