- pH (instrumental): Normal range 3.6 - 4.4
Note: New baths should be conditioned for 24 - 48 hours before use. At least one bath volume of UF permeate should be eliminated during this conditioning period. The MEQ and solvent content should be adjusted as necessary before commencing production.
Deposition Conditions
Depending on required thickness, 30 - 150 volts for 30 to 90 seconds
Curing Conditions
LC408 is able to cure at temperatures as low as 120°C. However, to exploit the enhanced chemical resistance it is practical to use 130°C for up to 60 minutes at metal temperature as a minimum temperature regime. Increasing the metal temperature up to 190°C will increase resistance properties without discoloration of the coating in correctly maintained ovens.
