3M Structural Glazing Tape has the ability of acrylic adhesives to withstand cold and hot temperatures, UV light exposure, humidity, and other environmental conditions has been documented through both real-life and accelerated aging studies. This tape has been found to be a good predictor of service durability and generally better than typical industry tests. Exposure was under high intensity UV light (Xenon Arc) with cycling heat and humidity. Tapes were bonded between glass and metal (black anodized aluminum) with UV exposure direct through clear float glass. The optimal thickness of the tape for a particular application depends on the size, rigidity, and flatness of the substrates, as well as the amount of application pressure applied to mate the surfaces together. In general, thicker tapes will handle greater mismatch and differential thermal movement between surfaces, and provide better contact and sealing.
