    Shelf Life Details 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. Performance of tapes is not projected to change even after shelf life expires, however, 3M does suggest that 3M™ VHB™ Tapes are used prior to the shelf life date whenever possible.

  • Best Practices for 3M 4930

    *See Terms of Use Below

    1. Surface Preparation

      Clean: Most substrates are best prepared by cleaning with a 50:50 mixture of isopropyl alcohol (IPA*) and water prior to applying 3M™ VHB™ Tapes.

      Exceptions to the general procedure that may require additional surface preparation include: Heavy Oils: A degreaser or solvent-based cleaner may be required to remove heavy oil or grease from a surface and should be followed by cleaning with IPA/water.

      Abrasion: Abrading a surface, followed by cleaning with IPA/water, can remove heavy dirt or oxidation and can increase surface area to improve adhesion.Abrasion is not suggested with 3M™ VHB™ Tapes 4932 and 4952.

      Adhesion Promoters: Priming a surface can significantly improve initial and ultimate adhesion to many materials such as plastics and paints.

      Porous surfaces: Most porous and fibered materials such as wood, particleboard, concrete, etc. need to be sealed to provide a unified surface.

      Unique Materials: Special surface preparation may be needed for glass and glass-like materials, copper and copper containing metals, and plastics or rubber that contain components that migrate (e.g. plasticizers).

      Refer to 3M Technical Bulletin “Surface Preparation for 3M™VHB™ TapeApplications” for additional details and suggestions. (70-0704-8701-5)

    2. Application

      TIme: After application, the bond strength will increase as the adhesive flows onto the surface (also referred to as “wet out”). At room temperature approximately 50% of ultimate bond strength will be achieved after 20 minutes, 90% after 24 hours and 100% after 72 hours. This flow is faster at higher temperatures and slower at lower temperatures. Ultimate bond strength can be achieved more quickly (and in some cases bond strength can be increased) by exposure of the bond to elevated temperatures (e.g. 150°F [66°C] for 1 hour). This can provide better adhesive wetout onto the substrates. Abrasion of the surfaces or the use of primers/adhesion promoters can also have the effect of increasing bond strength and achieving ultimate bond strength more quickly.

      Pressure: Bond strength is dependent upon the amount of adhesive -to surface contact developed. Firm application pressure develops better adhesive contact and helps improve bond strength. Typically, good surface contact can be attained by applying enough pressure to insure that the tape experiences approximately 15 psi (100 kPa) pressure. Either roller or platen pressure can be used.Note that rigids urfaces may require 2 or 3 times that much pressure to make the tape experience 15 psi.

      Temperature: Ideal application temperature range is 70°F to 100°F (21°C to 38°C).Pressure sensitive adhesives use viscous flow to achieve substrate contact area. Minimum suggested application temperatures: 50°F (10°C): 3M™ VHB™ Tapes 4950.

      To obtain good performanc ewith all 3M™VHB™Tapes, it isi mportant to ensure that the surfaces are dry and free of condensed moisture.
