VHB is foam tape acrylic adhesives which have excellent long term holding power. The peel adhesion and tensile holding power, significantly higher than typical pressure sensitive tape products. Resistance to solvents, temperature extremes
VHB has very good plasticiser resistance and adhesion to vinyl. Because of the wide variation in vinyl formulation, however, evaluation must be conducted with the specific vinyl used to insure that performance is satisfactory. Problems related to plasticiser migration can often be predicted by accelerated ageing at 65°C for one week.
There is a wide variety of paint systems available and specific recommendations cannot be made. For painted surface, Acrylic Foam Tape should be evaluated along with other VHB Tape products. Adhesion to plasticised materials
Plasticisers are common ingredients in many soft, flexible plastics. These plasticisers can migrate into adhesives causing a reduction in bond strength. Adhesive bond performance is dependent on the types and concentrations of plasticisers used in the plastic formulation. Acrylic Foam Tape is resistant to migration of many plasticisers and should be evaluated for applications requiring bonding to flexible plastics.
