MasterGlu Ultra-Thin is an extremely low-viscosity cyanoacrylate glue for applications where you need maximum penetration. Its ultra-thin consistency allows the glue to penetrate very small cracks, pores and seams through capillary action. It creates strong, durable bonds without building up material on the surface.
It is widely used in instrument repair, jewellery making, model making, wood stabilisation and advanced industrial applications. The glue reinforces delicate materials, stabilises cracks and secures small components where precision is crucial.
In woodworking, MasterGlu Ultra-Thin lets you stabilise porous woods, repair hairline cracks and reinforce delicate details. In jewellery making you can apply the glue precisely to small components without visible residue.
The fast curing ensures an efficient workflow and makes the product a valued tool in both the workshop and industrial production. You can speed up curing even further by combining the glue with GluBoost GluDry accelerators.
Once the glue has cured, you can sand the surface in stages, from coarse to fine grit, and then polish it to a high gloss.
