Are VHB tapes and structural adhesives better than mechanical fixing?
The use of very high bond (VHB) tapes and structural adhesives is now commonplace within the sign-manufacturing environment and often driven by the demands of design for concealed joining methods. VHB tapes are relatively quick and easy to apply to prepared surfaces, but are unsuitable where post-painting processes are required as heat and solvents will affect them. Structural adhesives perform well but typically require components to be clamped together during their cure time slowing process times likely to result in higher volumes of Work in Progress (WIP) . The use of adhesive bonding often results is a stronger, weatherproof join where the load is more evenly distributed.
