ThreeBond 7741, 7781, 7782, 7784

Instant adhesive fixes the adherends each other in several seconds to tens of seconds. Until now, it has been used in a wide range of fields as household or industry use because of its characteristics and general versatility.
We have introduced many instant adhesives to the market, and we have developed the product specialized to "bond in a fraction of a second" when we get back to the basic of them. This time, TB7700 series (referred to as Gold Label series) is commercialized.

1)	Improved initial bonding strength (set time) in several material
2)	More excellent long shelf life than ever
3)	Excellent adhesion to paper, hard-to-bond plastic, porous wood or so

1)	Suitable for application especially demanded for ultra-fast curing
2)	Suitable for paper material such as paper craft that it has been difficult to develop the initial bonding strength
3)	Suitable for porous and hard-to-bond materials when assembling or maintaining and repairing and wooden molds
4)	Suitable for bonding hard-to-bond plastic (e.g. PBT, POM, PPS)
