- 3M VHB Structural Glazing Tape is a double-coated 0.090 in. (2.3 mm) pressure sensitive adhesive tape for bonding many painted metals, as well as unpainted metals, and higher surface energy plastics. 3M VHB Structural Glazing Tape is appropriate for applications, which demand a thicker conformable product.
- Each 3M™ VHB™ Structural Glazing Tape application will be reviewed on a project specific basis. Application guidelines will be based upon adhesion test results generated by 3M Technical Service. These project specific application guidelines will be provided to the customer and must be followed during the glass bonding process. Listed below are some typical application guidelines for a 3M™ VHB™ Structural Glazing Tape project. However, these do not replace the project specific application guidelines provided by the 3M Technical Service Representative. 1. For maximum bond strength, non-glass surfaces should be thoroughly cleaned with a 50/50 IPA/water mixture to remove contaminants. Glass surfaces should also be cleaned with a 50/50 IPA/water mixture followed by treatment of the glass with a mixture of an IPA/water/Silane solution prior to tape application. Contact 3M for further information on appropriate Silane mixtures. Some surfaces may require additional surface preparation that will be determined on a project specific basis by a 3M Technical Services Representative. 2. Ideal tape application is accomplished when temperature is between 21 °C and 38 °C and the bond is allowed to dwell 72 hours. Initial tape application to surfaces at temperatures below 16 °C is not recommended. However, the use of a primer may lower the minimum application temperature. Contact 3M for more information. 3. Bond strength is dependent upon the amount of adhesiveto-surface contact developed. Flat bonding surfaces and firm application pressure develops better adhesive contact and helps improve bond strength. Generally, this means that the tape should experience at least 100 kPa in roll down, vacuum or platen pressure. 3M must approve pressure application equipment for 3M™ VHB™ Structural Glazing Tape applications. 3. After final bonding of the parts, immediate handling strength is achieved and glazed units can be moved as there is no curing mechanism in this process. However, the bond strength will continue to increase as the adhesive flows onto the surface. At room temperature, approximately 50 % of the ultimate strength will be achieved in 10-20 minutes after pressure application, 90 % after 24 hours and 100 % after 72 hours. The use of a primer may accelerate the bond strength build rate. Contact 3M for more information.
