THE IMPLICATIONS OF ACT PLATINUM COATING TECHNOLOGY ON THE GLASS INDUSTRY

Johnson Matthey's advanced coating technology (ACT) effectively combin es the best features and properties of the platinum group metals and c eramics and offers the glass industry improvements in component durabi lity and process efficiency. ACT coated thermocouple sheaths are now a n established worldwide product. The technology has been extended to t he coating of forehearth consumables. This has demonstrated major pote ntial for improvements in glass making; it has highlighted the benefit s possible in the control of gob diameter, shape and weight and brough t stability to forehearth operation. Significant reductions in downtim e now provide higher productivity and lower manufacturing costs.
