Wayne K Darvell, Patricia R Konsti, Jurgen Klingen, Karl W Kreckel: Pressure-sensitive tape construction incorporating resilient polymeric microspheres. Minnesota Mining and Manufacturing Company, Donald M Sell, Walter N Kirn, Richard E Brink, August 8, 1989: US04855170 (68 worldwide citation)

Tape products for diverse end users are obtained by applying to a sheet backing a layer of normally tacky and pressure-sensitive adhesive (PSA) containing and completely surrounding resilient non-tacky hollow thermoplastic polymeric microspheres. When the PSA is permanently bonded to the backing and ...

Jurgen Klingen, Patrick G Zimmerman: Pressure-sensitive adhesive tape containing hydrophobic silica. Minnesota Mining and Manufacturing Company, Donald M Sell, James A Smith, Richard Francis, December 1, 1987: US04710536 (59 worldwide citation)

By incorporating hydrophobic silica into acrylic pressure-sensitive adhesive tape, the shear strength at elevated temperatures is significantly improved, and adhesion and physical properties are maintained or improved. The hydrophobic silica preferably has a surface area from 50 to 400 m.sup.2 /g. A ...

George F Vesley, Jurgen Klingen: Dark acrylic pressure-sensitive adhesive. Minnesota Mining and Manufacturing Company, Donald M Sell, Walter N Kirn, Darla P Neaveill, January 23, 1990: US04895745 (26 worldwide citation)

A pressure-sensitive adhesive tape can be produced by photopolymerization and yet its pressure-sensitive adhesive layer can have a dark appearance when it contains a pigment or dye plus finely divided hydrophobic silica. As compared to a tape which is identical except for omission of the hydrophobic ...
