RoHS Compliant Plating OptionIntroductionRoHS Compliant Plating Optionfor Composite ThermoplasticConnectors and AccessoriesRoHS-Compliant9/2002/ EG5The 30 May 2008 MIL-DTL-38999 Rev Lspecification provides guidance on the useof alternative parts with less hazardousor nonhazardous materials. In this regard, thespecification provides for a number of alternativeplating materials. Users are directed to selectthe least hazardous plating material that meetsthe form, fit and function requirements of theirapplication.Glenair would like to draw our customer’sattention to one of the finish options from thisspecification that conforms to this guidance:T – Environment resisting Nickelfluorocarbon polymer.Conductive Nickel withfluorocarbon polymeradditives over a suitableunderplate to withstand 500hours of dynamic salt spraytesting.This MIL-DTL-38999L “T” plating solution iscadmium and hexavalent chromium free, whichallows it to be defined as RoHS compliant. NOTE:as of this printing the SAE AS85049 committeehas not yet defined plating codes for this finish.Glenair has developed its own Ni-PTFEsurface finish that meets all the D38999requirements but radically outperforms standardnickel fluorocarbon polymer flnishes in the mostimportant areas including an amazing 2000 hoursdynamic salt spray resistance when plated oncomposite parts.This Glenair nickel fluorocarbon polymerplating has been assigned the XMT code in theplating tables in this composite catalog. Here arejust some of the key performance attributes:Temperature Resistance: Glenair’s XMTNi-PTFE 1000 Hour Grey TM finish is rated from-65°C to +175°C.Plating adhesion: When tested as specifiedin 4.5.5, there shall be no blistering, peeling,flaking or separation of plating or other damagedetrimental to the operation of the part.Glenair Nickel-PTFE1,000 Hour Grey TM RoHSCompliant Plating isNow Available for AllComposite Connectorand Accessory Products.Dissimilar metals and compatible couples:The 1000 Hour Grey TM finish satisfies prohibitionsagainst dissimilar metal coupling as specified inMIL-STD-889.Shell-to-shell conductivity (millivolts): TheXMT finish is rated at 2.5 millivolt drop potential.Sulfur Dioxide Resistance: The XMT finishpasses the requisite 336 hours resistance toSulfur Dioxide.Please note that XMT may also be applied toaluminum alloy and stainless steel, in which casethe composite marker "X" is dropped and the platingcode changes to MT.© 2009 Glenair, Inc.CAGE Code 06324Printed in U.S.A.GLENAIR, INC. • 1211 AIR WAY • GLENDALE, CA 91201-2497 • 818-247-6000 • FAX 818-500-9912www.glenair.comIntro-21E-Mail: sales@glenair.com
