Product Name
Bron BT-9771 High-Strength Bond Tape – 40 mil
Brief Description
Bron BT-9771 is a 40 mil (0.040 inch) thick, high-strength, double-sided acrylic foam tape designed for demanding permanent bonding applications. It is known for its superior adhesive strength and ability to adhere to challenging surfaces. This tape absorbs and dissipates high dynamic loads, providing a secure and long-lasting fastening solution.
Popular Applications & Uses
- Mounting ABS plastics- Construction bonding- Joint sealing in various structures, including concrete- Automotive attachment of body side moldings, emblems, trim components, and exterior panels- Permanent assembly and structural bonding in manufacturing- Bonding lightweight skins to frames and stiffeners to panels- Attaching decorative materials and signs- Sealing, cushioning, and dampening vibration
Industries that Commonly Use It
- Aerospace/Defense- Automotive Service/Repair- Construction/ Building Services- Concrete- Cladding- General Manufacturing- Metal Fabrication- Plastic Fabrication- Sign & Display- LED/Electronics- Transportation/ Specialty Vehicle
Special and Unique Features
- High dynamic load absorption and dissipation- Creates a strong, permanent, and long-lasting bond- Can replace mechanical fasteners like screws, rivets, welds, and liquid adhesives- Provides an aesthetically pleasing, virtually invisible fastening solution- Offers shock absorption and vibration damping- Maintains strength and elasticity, even when stretching across surfaces- Resists stress and impact- Achieves full bond strength within 72 hours (50% in 20 mins, 90% in 24 hours)
