SILICONE PRESSURE SENSITIVE ADHESIVE COMPOSITIONS

The subsequent tack and adhesion of a silicone pressure-sensitive adhesive can be improved by incorporating into the adhesive a small amount of an organopolysiloxane resin having a majority of R3SiO1/2 siloxane units and the balance (R O)aSiO(4-a)/2, preferably SiO4/2, siloxane units. The resulting...

Beschreibung
Zusammenfassung:	The subsequent tack and adhesion of a silicone pressure-sensitive adhesive can be improved by incorporating into the adhesive a small amount of an organopolysiloxane resin having a majority of R3SiO1/2 siloxane units and the balance (R O)aSiO(4-a)/2, preferably SiO4/2, siloxane units. The resulting composition, when brought into contact with a release liner, such as a peelable protective sheet or the backside of the next turn in a roll of tape, have better tack and/or adhesion when separated from that liner than an analogous composition which does not contain the resin.
