Product Data Sheet

3M™ VHB™ Window Tape B45F is a conformable, double-coated acrylic foam tape engineered to provide a fast, reliable, and permanent bonding solution. Designed with a viscoelastic acrylic foam core, it offers exceptional strength while absorbing stress and adapting to surface irregularities—making it ideal for demanding window and door applications.

This tape replaces traditional mechanical fasteners like screws, rivets, and welds, helping streamline assembly while maintaining a smooth, clean appearance. Its pressure-sensitive adhesive bonds instantly on contact, allowing for quick handling and improved production efficiency.

Built for durability, B45F delivers outstanding resistance to UV exposure, temperature extremes, moisture, and environmental stress. It also forms a permanent seal against water and air infiltration, supporting long-term performance in both indoor and outdoor conditions.

With strong adhesion to materials such as glass, metal, vinyl, and composites, this tape enables the use of thinner, lighter components and supports modern design flexibility. Additionally, it is UL GREENGUARD® certified, contributing to healthier indoor air quality and LEED compliance.

Whether you’re looking to simplify assembly, improve aesthetics, or enhance long-term reliability, 3M™ VHB™ Window Tape B45F provides a proven, high-strength bonding solution.
