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 compound having a thiocarbonylthio structure.

Claims (25)

1. A two part adhesive comprising:

a first part comprising a decomplexing agent; and

a second part comprising an initiator, the initiator comprising an organoborane complex, wherein

at least one of the first part and the second part further comprises a first compound having a radically polymerizable group, and

at least one of the first part and the second part further comprises a second compound having a thiocarbonylthio structure.

2. The two part adhesive according to claim 1 , wherein the first part comprises the second compound having the thiocarbonylthio structure.

3. The two part adhesive according to claim 2 , wherein the first part comprises the first compound having the radically polymerizable group.

4. The two part adhesive according to claim 3 , wherein the first part further comprises a filler.

5. The two part adhesive according to claim 1 , wherein the second part further comprises a filler, a cross-linking agent, and a plasticizer.

6. The two part adhesive according to claim 1 , wherein both parts of the two part adhesive are free of any halogenated metal salt.

7. An adhesive composition consisting essentially of:

a decomplexing agent;

an organoborane complex;

a compound having a radically polymerizable group;

a compound having a thiocarbonylthio structure;

a filler;

a cross-linking agent; and

a plasticizer.

8. 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 first part and the second part of the two part adhesive according to claim 1 .

9. A method for manufacturing the adhesive body according to claim 8 , the method comprising:

pasting the first adherend and the second adherend together with the adhesive composition comprising the first part and the second part.
