The properties of cured 3M™ Scotch-Weld™ Epoxy Adhesive DP420 NS Black and 3M™ Scotch-Weld™ Epoxy Adhesive DP420 LH are expected to be similar to the properties of 3M™ Scotch-Weld™ Epoxy Adhesive DP420 Black and 3M™ Scotch-Weld™ Epoxy Adhesive DP420 Off-White, respectively as described by data in the following sections of this technical data sheet. An exception to this is the concentration of halogens in 3 M™ Scotch-Weld™ Epoxy Adhesive DP420 LH. 3M™ Scotch-Weld™ Epoxy Adhesive DP420 LH is a form of 3M™ Scotch-Weld™ Epoxy Adhesive DP420 Off-White that can be considered “low halogen”. Low halogen is defined by the Electrotechnical Commission (IEC) 61249-2-21 standard as having less than 900 ppm chlorine, 900 ppm bromine, and less than 1500 ppm total chlorine and bromine. 3M™ Scotch-Weld™ Epoxy Adhesive DP420 LH Test Results Halogens (determined by ion chromatography) Total Chlorine (ppm) Total Bromine (ppm) Total Halogens (ppm) 720
