Composition for pressure-sensitive adhesive, pressure-sensitive adhesive resin tape, and wire harness
The present invention relates to a composition for a pressure-sensitive adhesive comprising 100 parts by mass (non-volatile fraction) of a main agent comprising a mixture of a natural rubber latex and a synthetic rubber latex, 40 to 120 parts by mass of a rosin-based tackifier resin having a softening point of 130 to 135° C. and 1 to 15 parts by mass of low-molecular-weight polyisoprene having a weight-average molecular weight of 15,000 to 40,000.
1. A composition for a pressure-sensitive adhesive, comprising:
100 parts by mass (non-volatile fraction) of a main agent comprising a mixture of a natural rubber latex and a synthetic rubber latex;
60 to 100 parts by mass of a rosin-based tackifier resin having a softening point of 130 to 135° C.; and
3 to 7 parts by mass of low-molecular-weight polyisoprene having a weight-average molecular weight of 15,000 to 40,000.
2. A pressure-sensitive adhesive resin tape comprising:
a pressure-sensitive adhesive layer; and
a resin substrate,
wherein the pressure-sensitive adhesive layer comprises the composition for a pressure-sensitive adhesive according to claim 1 .
3. The pressure-sensitive adhesive resin tape according to claim 2 ,
wherein the resin substrate comprises a polyvinyl chloride resin.
4. The pressure-sensitive adhesive resin tape according to claim 2 ,
wherein the pressure-sensitive adhesive layer has a thickness of 5 μm to 20 μm.
5. A wire harness comprising the pressure-sensitive adhesive resin tape according to claim 2 .
