Problem: Hose becomes clogged
Soultion: If the dispenser hasn’t been used for a week or longer,
activate the system for a few seconds by turning on the tank valves
and squeezing the trigger fully without a nozzle attached to dispense
twin streams into a waste container. This clears and re-pressurizes the
hoses and should be done weekly when the system is idle. Re-apply
petroleum jelly and reinsert used nozzle for storage.
Identifying and fixing an off ratio foam mix
Please perform these tasks before returning kit to Dow.
Your ratio may be uneven if:
• Foam will not cure completely, is soft to
the touch or sags off the substrate. This
means the B tank is dispensing quicker
than the A tank, causing an off ratio mix.
• Foam cures and looks brittle and flaky with “honeycomb” type
areas. This means the A tank is dispensing quicker than the B tank,
causing an off ratio mix.
• Either of the two above can occur if the tank product is low and
needs to be replaced.
Solution:
1. Turn both A and B tanks off.
2. Remove Spray Tip.
3. Check temperature of the tanks. Should be 7585° F
(2429° C) for optimal performance.
4. Shake both A and B tanks for 45 seconds.
5. Turn B tank on and purge into empty trash can.
Continue to engage the gun trigger for 3060 seconds
until a consistent stream is seen. Turn B tank off.
6. Turn A tank on and purge into empty trash can. Continue to
engage the gun trigger for 3060 seconds until a consistent
stream is seen. Turn A tank off.
7. Connect a new spray nozzle.
8. Fully turn on both the A and B tanks.
9. Test spray into empty trash to ensure foam is curing correctly.
10. Complete the project.
Section 8
Disposal and Clean-up
Disposal must be performed in a well-ventilated area (preferably
outdoors). Never puncture or incinerate cylinders.
1. Wear the same PPE (personal protective equipment) as
used while applying the two-component foam (i.e., NIOSH
approved negative respirator with organic vapor cartridges
and P100 particulate filters, goggles/face shield, gloves and
protective clothing).
2. Liquids (A & B) remaining in FROTHPAK
™
kits must be
disposed of as solid waste foam material, not liquid chemicals.
Steps 3 through10 are intended guidelines necessary to
convert any residual liquids into solids prior to proper disposal.
3. Carefully dispense liquids from the cylinders with the gun
and nozzle attached. Dispense liquid materials out of the
cylinder(s) as foam until one or both components/
cylinder(s) are empty.
4. Carefully remove the nozzle from the gun and continue to
depressurize the cylinder(s) by dispensing the liquid materials
into a waste container lined with a plastic bag that has
adequate absorbent (e.g., sawdust, kitty litter, dry absorbent)
in the bottom.
5. Carefully close both cylinder valves completely, then operate
the gun trigger to empty and depressurize the hoses.
6. Lift each cylinder. The cylinder should feel empty, with no
sloshing of liquid.
