Quality Sticks

O3a is a dedicated range of Cyanoacrylate Adhesives specifically developed to meet the requirements of makers and crafters.

For years we have used Cyanoacrylate Adhesives, and we have all experienced the same frustrations.  Some set too quickly, some set too slowly, some are too thick, some are too thin, and in most cases don't set clear.

With O3a Cyanoacrylate Adhesives, you are able to be in full control of when the adhesive sets, by using the non staining low odour O3a Aerosol Activators that set the adhesive in less than 20 seconds, allowing you the time to get the fit "just right". 

At O3a, we have developed three dedicated viscosities from thin  to thick which cater for all situations ranging from gap filling with our O3a Thick which comes in a crystal clear and a black version to the everyday O3a Medium and the fantastic O3a Thin version.

O3a is a Premium Cyanoacrylate Adhesive that shows minimal blooming (the crystallic whitening that Cyanoacrylate develops as it dries).

We are sure that you will love O3a Cyanoacrylate Adhesives and Aerosol Activators as much as we do.

so many applications

Pen Finishing

The easiest and most common way to finish a pen quickly. It requires you to shape the pen in the way you want, sand it, and then apply coats of Cyanoacrylate (CA) adhesive.

Blue Tape Trick

Apply adhesive to blue tape on one piece of wood and activator to blue tape on another.

Knot Filling

Due to its colour and thick consistency,O3a Black Thick Cyanoacrylate Adhesiveis 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.

From our users

Wow .. love the black thick. Its perfect for small cracks and voids in my period furniture.

Tobias - Swellendamd

We have recently been introducted to these products. O3a hits the spot for both bonding and spot filling. That combined with a very sensible price point - this is our go too for anything and everything now. Great to support a product made in the UK.

Ben Goldsmith - Designs Woodcraft

I use this for everything from installing magnetic latches to small gap filling. Great product. Love the long open time paired with the activator. Won't use anything else!
