Abstract : Silicone rubber potted firing modules were found to be very susceptible to fungus growth. Two fungicides, copper-8-quinolinolate and p-chlorom-xylenol, were incorporated into coatings with and without added red pigment. The coatings containing 2% p-chloro-m-xylenol were ineffective, whereas coatings containing 0.25% of solubilized copper-8-quinolinolate were effective in preventing fungus growth but showed some blooming of the fungicide on the coating. Polyurethane was evaluated as a material for possible future use in the design of firing modules. A concentration of 2% p-chloro-m-xylenol was ineffective in preventing fungus growth on the polyurethane, while a concentration of 0.25% copper-8-quinolinolate prevented the development of fungus growth but evidenced some blooming of the fungicide.
