Viscosity determined using 3M test method C-1D. Procedure involves Brookfield RVF, 7 spindle, 20 rpm and 80F (26C). Measurement taken after 1 minute rotation. 2. Worklife determined using 3M test method C-3180. Procedure involves periodically measuring a 2 gram mixed mass for self- leveling and wetting properties. This time will also approximate the usable worklife in an 3M EPX Applicator mixing nozzle. 3M Scotch-Weld Epoxy Adhesives DP190 Translucent and Gray Note: The following technical information and data should be considered representative Typical Cured or typical only and should not be used for specification purposes.
