Scotch-Weld\u2122 DP-460 and DP-420 Epoxy Adhesives are supplied in dual syringe plastic Duo-Pak cartridges as part of the 3M EPX\u2122 Applicator System. The Duo-Pak cartridges are supplied in 37 ml, 200 ml and 400 ml configurations. To use the 37 ml cartridge 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 simultaneous mixing of Part A\u00a0and Part B is desired, attach the EPX mixing nozzle to the Duo-Pak cartridge and begin dispensing the adhesive.<\/p>\n

 <\/p>\n

With the 200 ml and 400 ml cartridges the nozzle must be attached before dispensing any material to prevent unmixed adhesive from getting into the applicator cartridge holder. A small quantity of material should be discarded until uniform color, consistency of product and even flow is evident.<\/p>\n

 <\/p>\n

When mixing Part A and Part B manually (Scotch-Weld 460 B\/A Epoxy Adhesive or Scotch-Weld 420 B\/A Epoxy Adhesive), the components must be mixed in the ratio indicated in the Typical Uncured Properties Section of this Technical Data Sheet (page<\/p>\n

1). Complete mixing of the two components is required to obtain optimum properties.<\/p>\n

Two-part mixing\/proportioning\/dispensing equipment is available for intermittent or production line use. These systems are ideal for line uses because of their variable shot size and flow rate characteristics and are adaptable to most applications.<\/p>\n
