Product Description
4611F is a dark grey double coated acrylic foam tape with a high tack acrylic adhesive.
This tape has a plain red filmic liner.
The excellent temperature performance enables bonding of materials prior to processing in a powder coating line

Additional Product Information
This product is suitable for plasticised PVC but is not suitable for low surface energy plastics.
Application Techniques
1. Bond strength is dependent upon the amount of adhesive-to-surface contact developed. Firm application pressure develops better adhesive contact & thus improves bond strength.
2. To obtain optimum adhesion, the bonding surfaces must be clean dry and well unified. A typical surface cleaning solvent is isopropyl alcohol & water. Use proper safety precautions for handling solvents.
3. Ideal tape application temperature range is 20°C to 40°C. Initial tape application to surfaces at temperatures
below 10°C (50°F) is not recommended because the adhesive becomes too firm to adhere readily. However
once properly applied low temperature holding is generally satisfactory.
Applications
4611F is a high performance double coated acrylic foam product which possesses a good balance between shear peel and high tack adhesion. It has been designed to be suitable for a range of bonding applications which require a level of adhesion higher than standard double coated foam tapes but perhaps lower than higher performance 3M VHB™
tapes.
Typical applications include:
— Bonding roof bows on trucks and buses.
— Bonding glazing (muntin) bars or muntin bars positioned internally.
— Signage applications.
