Abstract

An adhesive set includes a main agent containing a decomplexing agent and an initiator containing an organoborane complex. At least one of the main agent and the initiator further contains a compound having a radically polymerizable group. At least one of the main agent and the initiator further contains a polymerization control agent. At least one of the main agent and the initiator further contains a peroxide.

Claims (28)

1 . An adhesive set comprising:

a main agent comprising a decomplexing agent; and

an initiator comprising an organoborane complex, wherein

at least one of the main agent and the initiator further comprises a compound having a radically polymerizable group,

at least one of the main agent and the initiator further comprises a polymerization control agent,

at least one of the main agent and the initiator further comprises a peroxide, and

the polymerization control agent comprises at least one selected from the group consisting of a halogenated metal salt and a compound having a thiocarbonylthio structure.

2 . An adhesive body comprising:

a first adherend;

a second adherend; and

an adhesive layer interposed between the first adherend and the second adherend, the adhesive layer bonding the first adherend and the second adherend to each other, wherein

the adhesive layer comprises a cured product of an adhesive composition comprising the main agent and the initiator of the adhesive set according to claim 1 .

3 . A method for manufacturing the adhesive body according to claim 2 , the method comprising:

pasting the first adherend and the second adherend together with the adhesive composition comprising the main agent and the initiator.

4 . The adhesive set according to claim 1 , wherein the initiator further comprises a filler, a cross-linking agent, and a plasticizer.

5 . The adhesive set according to claim 1 , wherein the main agent comprises the compound having the radically polymerizable group, the polymerization control agent, and the peroxide.

6 . The adhesive set according to claim 5 , wherein the main agent further comprises a filler.

7 . The adhesive set according to claim 1 , wherein the polymerization control agent comprises the halogenated metal salt.

8 . An adhesive composition consisting essentially of:

a decomplexing agent;

an organoborane complex;

a compound having a radically polymerizable group;

a polymerization control agent;

a peroxide;

a filler;

a cross-linking agent; and

a plasticizer,

wherein the polymerization control agent comprises at least one selected from the group consisting of a halogenated metal salt and a compound having a thiocarbonylthio structure.
