We are pleased to offer the support of our in-house Technical Team for future product development where appropriate.
With over a century of successful formulation and manufacturing experience, ITAC is today positioned at the forefront of the adhesive revolution, which is currently underway. Our laboratory provides first class facilities for the development of our ITS technically advanced range of industry specific adhesives.
This gives us an extraordinary depth of adhesive knowledge that we refer to as our “collective adhesive brain”. It is a vast resource, which is available for use independently for research, or alternatively it can be project linked with our extensive manufacturing plant to provide a turnkey adhesive / coating solution.

Scientists at Newcastle University have, for the first time, successfully 3D printed human corneas using a unique gel. The cornea is the outermost layer of the human eye, with a key role in focusing vision.
There are currently around 10 million people worldwide in need of surgery to prevent corneal blindness, which results from diseases such as trachoma – an infectious eye disorder. Another 5 million are already blind due to corneal scarring from burns, lacerations, abrasion or disease.
There is a major shortfall of corneas available to transplant. This new technique could potentially be used to produce an unlimited supply of corneas.
The Newcastle team conducted proof-of-concept research, the resulting reports show how stem cells (human corneal stromal cells) from a healthy donor cornea were mixed together with alginate and collagen to create a solution that could be printed, a ‘bio-ink’.
The researchers used a basic low-cost 3D bio-printer, to successfully extrude the bio-ink in concentric circles to form the shape of a human cornea. Print time was under 10 minutes. The stem cells were then shown to culture or grow.
By scanning the patient’s eye, the team demonstrated that it could create a cornea to match a patient’s unique specifications. This enabled accurate rapid printing of a cornea.
Che Connon, Professor of Tissue Engineering at Newcastle University, who led the work, said: “Many teams across the world have been chasing the ideal bioink to make this process feasible. Our unique gel – a combination of alginate and collagen – keeps the stem cells alive, whilst producing a material which is stiff enough to hold its shape but soft enough to be squeezed out the nozzle of a 3D printer”.
This method has huge potential to combat the worldwide shortage of corneas. However, further tests will now be needed, prior to the technique being used for transplants.
