O3a Cyanoacrylate Adhesive, Medium, 50g

by O3a


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.  

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

We highly recommend O3a Aerosol Accelerator when saturation of a porous object is unwanted, as the instant cure enabled by the O3a Aerosol Accelerator effectively prevents the adhesive from excessively soaking into the porous object, and also therefore reduces wastage of the product.
