3M VHB Tapes provide the convenience and simplicity of a tape fastener and are ideal for use in many interior and exterior bonding applications. These 3M VHB Tapes are made wtih acrylic foam which is viscoelastic in nature. This gives the foam energy absorbing and stress relaxing properties which provides these tapes with their unique characteristics. The acrylic chemistry provides outstanding durability performance. These tapes utilize a variety of specific foam, adhesive,color and release liner types to provide each product/family with specific features. These features can include adhesion to specific or a broad range of materials,conformability,high tensile strength,high shear and peel adhesion,resistance to plasticizer migration,and UL746C recognition. All 3M VHB Tapes have excellent durability and excellent solvent and moisture resistance. 3M VHB Tapes Adhesive Types: Multi-Purpose Acrylic:This adhesive bonds to a wide range of materials including metals,glass,and high and medium surface energy plastics and paints. This unique adhesive also has the ability to resist mmigration of plasticizers in vinyl substrates. Modified Acrylic:This adhesive bonds to medium low surface energy paints and plastics,including many poweder coated paints in addition to the substrates listed with the multi-purpose acrylic adhesive(except plasticized vinyl). General Purpose Acrylic:This adhesive bonds to most higher surface energy substrates including metal , glass and high surface energy plastics. Low Surface Energy:This high performance synthetic adhesive bonds to many lower surface energy substrates, including many plastics and power coated paints,plus smooth general purpose substrates. 3M VHB Tapes Foam Types: Conformable:This foam provides high strength with the capability of conforming to the irregularities of rigid substrates, even when there might be slight mismatch. Very Conformable:This foam provides the highest level of conformabilit while maintaining high internal strength. Firm:This foam provides the highest level of foam strength in the 3M VHB Tapes family. Clear:Not technically a foam,this solid acrylic material provides excellent clarity.
