Note: The following technical information and data should be considered representative
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 Scotch-Weld DP420 LH.
Scotch-Weld DP420 LH is a form of Scotch-Weld 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.
