Handling/Curing
Information
Directions for Use
1. For high strength structural bonds, paint, oxide films, oils, dust, mold release
agents and all other surface contaminants must be completely removed. However,
the amount of surface preparation directly depends on the required bond strength
and the environmental aging resistance desired by user. For specific surface
preparations on common substrates, see the section on surface preparation.
2. These products consist of two parts.
Mixing
For Duo-Pak Cartridges
Scotch-Weld epoxy potting compound/adhesive DP270 Clear and Black are
supplied in a dual syringe plastic duo-pak cartridge as part of the 3M™ EPX™
Applicator systems. To use, simply insert the duo-pak cartridge into the EPX
applicator and start the plunger into the cylinders using light pressure on the
trigger. Next, remove the duo-pak cartridge cap and expel a small amount of
adhesive to be sure both sides of the duo-pak cartridge are flowing evenly and
freely. If mixing of Part A and Part B is desired, attach the EPX applicator mixing
nozzle to the duo-pak cartridge and begin dispensing the adhesive. For hand
mixing, expel the desired amount of material and mix thoroughly to obtain a
uniform color.
For Bulk Containers
Mix thoroughly by weight or volume in the proportions specified in the typical
uncured properties section to obtain a uniform color.
