Special Considerations
1. Do not use primers with 3M GPH tapes. GPH tapes work best at high temperatures when adhered directly to the substrate.
2. 3M GPH Tapes are compatible with chemicals typically used in paint pre-treatment processes (spray and dip). Tests completed by a supplier have determined that the tape does not cause premature degradation of chemical solutions.

Design Considerations
Adhesion to the substrate is important in achieving bonding success. Adhesives must flow onto the substrate surfaces to achieve intimate contact area. 3M™ VHB™ Tape GPH series products bond well to high (HSE) and medium (MSE) surface energy materials.
Using the right amount of tape is important to handle the expected stresses. As a general rule, for static loads, approximately four square inches of tape should be used for each pound (57 cm² of tape per kg) of weight to be supported. For dynamic loads, a useful design factor is 12 lb/in² (85 kPa).
Allow for thermal expansion/contraction. 3M™ VHB™ Tapes can typically tolerate differential movement in the shear plane up to 3 times their thickness.
Storage and Shelf Life
All 3M™ VHB™ Tapes have a shelf life of 24 months from date of manufacture when stored at 40°F to 100°F (4°C to 38°C) and 0-95% relative humidity. The optimum storage conditions are 72°F (22°C) and 50% relative humidity.
