ACT® Furnace Blocks
Johnson Matthey has two robot spray booths which are used to apply the ACT® coating. Due to the weight of some ceramic substrates, each booth is equipped with heavy lifting and handling equipment.

ACT® Furnace Blocks
The protective ACT® platinum coating is systematically built up using a carefully designed profile. It is applied using a highly sophisticated industrial robot. You can select the video clip option in the document zone to see the spray process in action.

ACT® Furnace Blocks
This is a throat roof block for a borosilicate glass furnace. Protecting this block, as well as the throat block itself, completes the protection of the throat assembly and will increase the lifetime of the furnace.

This is an ACT® coated throat screen block for an opal glass furnace. It is an example of the growing number of furnace block applications of the ACT® technology.

This screen block is one of the larger substrates ACT® coated by Johnson Matthey. It is around 2 metres wide. Equipment has been installed to enable the safe handling of such large, heavy components.

ACT® Furnace Blocks
This fusion-cast AZS drain block is one of the more complex parts protected with ACT® coatings. The critical glass contact areas are fully protected, whilst the amount of platinum used is kept to an absolute minimum.

ACT® Furnace Blocks
This throat cover block was one of the many large fusion-cast blocks routinely being ACT® coated. The increasing number, size and weight of these parts has required an extension to the noble metals factory and a second robot coating booth.

This is a throat block for a borosilicate glass furnace. As this is such a critical component, the dense zircon block has been almost entirely coated with ACT® platinum coating.

These are two AZS finger bar glass test samples. The unprotected sample shows extreme glass line corrosion. The ACT® coated finger bar is in perfect condition and demonstrates the highly protective capability of the platinum coating.

This fusion cast AZS corner block splits an opal glass flow into two forehearth channels. This is the most corrosive position in the forehearth.

This is an example of a cover block that has been fully protected by Johnson Matthey ACT® coating technology.

ACT® Furnace Blocks
This is an ACT® coated skimmer block after 18 months in opal glass. This block has been completely protected by the platinum coating, but the adjacent unprotected block had been corroded to almost half its thickness at the centre.
