Johnson Matthey formulates and manufactures high purity technical glasses. We can toll manufacture to customer specification or consultation to co-develop glass to specific customer needs.
Glasses can be supplied as frit, powder or paste.
Using a range of state-of-the-art melting technologies we typically supply glass for order quantities in the range 1.0Kg - 50MT. We have the ability to handle heavy metal oxides as well as process heavy metal free formulations within close tolerances.
Our grinding technologies, wet or dry, are capable of producing material to a custom particle size and distribution and we have a range of drying technologies which can be adopted depending on final product requirements.
We offer extensive pasting technologies and media systems which can be formulated for a specific application and substrate.
