O3a Black Thick Cyanoacrylate Adhesive is a proprietary rubber-toughened, thick CA adhesive that dries completely jet black in colour.

Due to its colour and thick consistency, O3a Black Thick Cyanoacrylate Adhesive is first choice for filling small to medium imperfections in your timber, void filling where a dark result is required and for artistically accentuating and stabilising natural cavities in your projects. 

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

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

Please note: Due to the addition of the proprietary rubber compound in O3a Black Thick Cyanoacrylate Adhesive, the product has a longer effective bonding time.

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 cure. In these situations, we strongly recommend the use of O3a Cyanoacrylate Aerosol Accelerator.
