Letter 28042 Need Dacromet without chrome-6 [UK]++++ We currently use Dacromet coating on socket screws and large bolts. Our customer has asked that we change from Dacromet to a non hexavalent (?) finish. We need to retain all the other qualities of Dacromet, eg, Saltspray resistance, suitability for threaded components etc. Please advise a suitable treatment. John McCarthy
Mar14 ++++ The manufacturer of Dacromet, Metal Coatings International, offers a chrome-free system called Geomet. I cannot say whether or not all of the qualities of Dacromet are fully maintained, but that was the intention.
