O3a Medium Cyanoacrylate Adhesive is an instant ethyl cyanoacrylate adhesive. With medium consistency, it is the most popular general use CA adhesive in the entire O3a Cyanoacrylate range consistency.  

O3a Medium Cyanoacrylate Adhesive is well suited for bonding a vast range of materials from acrylic fingernails, plastic and wooden models, metals, gemstones, ceramics, metal and stone powders, inlay, parquetry, marquetry, leather and an extremely wide variety of other substrates. 

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.

The use of O3a Aerosol Accelerator is advised when saturation of a porous object is unwanted. The instant cure will prevent the glue from excessively soaking into the porous object, and prevent waste.
