Directions for standard use: (Specific polyethylene bonding directions below.)
1.
Note caution information on dispenser.
2. Clean and roughen all bonding surfaces with MEK.
3. Remove cap by twisting counterclockwise 1/4 turn, then pull out.
4. Push Static Mixer (nozzle) on to the cartridge, twist 1/4 turn clockwise to lock.
5. Insert epoxy cartridge in Dispensing Gun or Caulking Gun Adaptor.
6. Discard the first 3" of material ejected from the epoxy cartridge. You will notice that this material is not consistent in color and should not be used for bonding.
7. Apply epoxy to bonding surfaces, press together leaving epoxy between joints.
8. Remove Static Mixer and replace cap on nozzle.
9. Clean un-cured epoxy with rubbing alcohol.
10. Working time is 15-30 minutes, material will set in 1-2 hours, full cure in 24 hours at 72°F.
11. Longer cure times at lower temperatures.
Directions for bonding polyethylene using flame treating:
1.
Fit a propane torch with a flame spreader.
2. Following the operating cautions of the propane torch, ignite the flame.
3. Observe the flame in a darkened room, noting the primary (bright blue) and secondary (faint yellow) portions of the flame (see drawing.)
4. Adjust the flame so that the primary flame is contained within the spreader, and the secondary flame is 1-1/2" beyond the spreader (see drawing.)
5. Treat the polyethylene to be bonded with the tip of the secondary flame by passing it over the polyethylene in 5 gentle strokes. Total exposure to the flame should be 2-3 seconds (.5 second per stroke.) This light exposure should not deform or melt the polyethylene in any way.
6. Test the polyethylene for bond readiness by wetting it with water. If the water runs off immediately, the treatment was not effective. If the water sheets on the surface, the surface is ready for bonding. If unsure, compare the water's action on the treated area with the untreated area.
7. Bond joints per the above directions within 1 hour after flame treating. Always prepare test bonds to be certain that flame treating is effective with your material.
