O3a Cyanoacrylate Adhesive, Thick, 50g

by O3a


O3a Thick Cyanolacrylate Adhesive is an excellent choice for filling small to medium imperfections in your timber, void filling where a clear result is required and for artistically accentuating and stabilising natural cavities in your projects. 

O3a Thick Cyanoacrylate Adhesive easily penetrates into the substrate to bond your components quickly and effectively. It can be sanded by hand or machine and can be polished to an exceptionally high gloss. 

O3a Thick Cyanoacrylate Adhesive is commonly used for crack filling in artisanal wooden counters and table tops, for bowl and spindle woodturning and creative inlays. 

Generally, good bonding is achieved within 30-60 seconds. If the area to be glued/filled is large and/or deep, the adhesive will accordingly take longer to bond and fully cure. In these situations, we strongly recommend the use of our O3a Cyanoacrylate Aerosol Accelerator.
