POLYSET - Northeast Foam

1 The ProPack 30 s & 100 s are being used in many regionswith great results. There have, however, been some instancesof clogging within the gun/hose assembly. Research indicatesthe foam adhesive in the nozzle (which is a static mixer) willcontinue to expand, and if left attached to the gun assembly,will eventually cure and block the nozzle. This can happen in ashort period of time, due to the small quantity of foam adhe-sive in the nozzle. When the installer activates the gun, the twochemical components (which are under pressure) will hit thisblockage and back up into the gun/hose assembly. Usually,when this occurs, the gun will dispense only one chemical,rendering the gun unusable and must be : This condition is avoidable and is not caused by anydefect in the ProPack gun or recommends the removal of the static mixer nozzleas the installer stops spraying for any reason, ( stopping tomove tile, taking a break, making tile cuts, etc.)

Each ProPack has beenprovided with ten extra nozzles to enable the installer toreplace when necessary. In addition, petroleum jelly (alsoprovided with the ProPack ) should be placed on the gun portswhenever the gun is not in use. This will prevent the portsfrom sticking due to the reaction with is important for the installer to remember that the ProPack is an adhesive dispenser and all adhesives react to heat,moisture and air. Properly used, the gun/hose assembly willdispense the contents of the ProPack without any used, the gun/hose assembly will clog resulting inunnecessary downtime and extra replacement gun/hose assemblies can be purchasedthrough your local distributor or at Polyfoam Products, free Up Your SystemIMPORTANT: Follow InstructionsPROPACK systems are factory tested to meet rigid perfor-mance standards.

3 Proper function of the unit in the field,however, depends on close adherence to the instructions in thismanual (see Safety Precautions, page 4).Components:Systems come with a gun/hose assembly, 10 mixing nozzles,packet of petroleum jelly, and wrench. Components are packedin the base of the PROPACK 30 and at the top of the A carton of the PROPACK 100. Petroleum jelly is applied to thegun face at the factory. It need only be used for storage and the Gun and Hoses:Set up your PROPACK system in a clean area to prevent dirtor other foreign matter from contaminating Operator should always wear goggles and Attach hoses to tanks:1. Place the PROPACK 30 on its side. Remove punch outtab on the PROPACK 100 system Attach A labeled hose to A tank valve. Turn collarnut down by hand and secure with wrench (Fig. 1).Repeat with B hose. Make sure the PROPACK 30cartons are turned upright (valves down) andPROPACK 100 cartons are turned upright (valves up).

4 3. Open the A valve slightly (tilt the PROPACK 30carton slightly to reach under). Check for leakage. Ifthere is none, open valve completely. If there is, makesure nut is securely positioned and tightened. Repeatwith the B :NEVER OPEN VALVES UNLESS THEY ARE POINTED DOWN FOR THE PROPACK 30, UP FOR THE PROPACK Using a small amount of petroleum jelly, lubricate the o-ring that surrounds the face of the gun. Install mixingnozzle. Align nozzle locking arms with slots in gun in firmly until you hear a click . Nozzle is thenfirmly secured (Fig. 2).D. Check operation. Aim gun into waste container. Disen-gage safety. Dispense foam at full pressure to make surechemical is feeding from both tanks and reacting to makequality To remove nozzle, squeeze locking arms and pull nozzleout (Fig. 3).The patented U-CONTROL GUN permits the operator tometer the flow of material, dispensing only the amount of foamrequired for the particular job.

5 Simply hold the gun as youwould a pistol and pull evenly on the trigger until you obtainthe desired :DO NOT USE SOLVENTS SUCH AS METHYLENECHLORIDE OR ACETONE, TO ATTEMPT TO CLEANTHE GUN OR common rule of thumb is to hold the nozzle about 6 inchesfrom the area to be foamed. You can control the volume offlow by the amount of pressure you apply to the trigger. Get asclose to the target as possible to achieve maximum coveragewith minimum Setup TimePOLYPRO AH160 sets up (tack free or dry to touch) in lessthan two minutes at temperatures between 70 and 80 F (21 -27 C). The higher the temperature, the faster the set-up. Theoperator must be aware of time lapsing between shots (dis-pensing).RAPID CHEMICAL SET-UP WILL OCCUR INNOZZLE AND BLOCK THE PORT OPENING. THERE-FORE, IF WORK IS INTERRUPTED BY A TIME SPANOF MORE THAN 60 SECONDS, REMOVE FactorsSurface PreparationThe substrate surfaces must be free from dust, dirt, oils, waterand other plays a major role in the cure time, density andphysical properties of foam.

6 Kits should be stored at between60 and 90 F (16 and 32 C). At time of use, the chemicaltemperature must be between 60 and 95 F (16 and 35 C).When the storage or work area temperature drops below 60 F(16 C) the chemical must be warmed to a working tempera-ture of at least 70 F (21 C). Proper chemical performancecannot be guaranteed if proper temperature recommendationsare not followed. Ideally, the best results are obtained when theambient temperature of the work environment is 70 to 95 F(21 -35 C). Properly heated foam can be sprayed on coldersurfaces, but it must be understood that cold surfaces, gener-ally those below 50 F (10 C), slows down the chemicalreaction which causes the foam to expand. Spraying onto coldsurfaces can reduce expected yields by as much as 25% andalso affect foam quality. Cold surfaces should be warmedartificially if possible, or delay foaming until surface tempera-tures have been warmed by the sun or interior PROPACK cannot be metered, operator skill isimportant in obtaining economical yields.

Theoperator also must remember that the foam will expand 2-3times its originally dispensed volume or size and to allow forthis expansion.

Once thetank valves are opened, the chemicals should be used within30 days. Systems must be stored at 60 to 90 F (16 -32 C)whether opened or unopened.

8 If it is necessary to store them attemperatures under 60 F (16 C) for a short period of time,they must be returned to an environment of 60 to 80 F (16 -27 C) for at least 24 hours before they can be used. In noevent should units be stored at temperatures above 100 F (38 C). Nor should they be stored in direct sun, or near hot waterpipes, furnaces, chimneys or heat ducts. Do not place contain-ers directly onto the roof deck when ambient temperaturesexceed 90 F (32 C). When ambient temperature exceed 90 F (32 C) place containers on a stack of roof tiles or on aplatform elevating them off of the roof AND RE-USE CRITICAL TO PROPERSYSTEMS OPERATION1. Engage Safety. Make sure used nozzle is removed anddiscarded. Coat face of gun with petroleum Apply petroleum jelly to valve stems and close Make sure cartons are turned upright (valves pointedDOWN for the PROPACK 30 and UP for the PROPACK 100).

10 Itis very easy for the nozzle to clog due to the small quantity offoam adhesive which remains in the nozzle when dispensing ofthe material is suspended. Replace with a new nozzle andcontinue with the tile installation. This practice will preventpotential blockage in the gun/hose assembly. If the gun isactivated with a clogged nozzle, chemical will back up into thegun/hose assembly rendering the gun unusable. Blockageoccurs and usually only one chemical will be dispensed. Thegun/hose assembly will then have to be PrecautionsPROPACK tanks are pressurized. When in use they must notbe punctured or incinerated. They can only be used once, andare not refillable. The A tank contains polymeric isocyan-ates. The B tank contains polyolamines. The user shouldmake sure that the intended application of this productconforms with all local codes. Wear gloves and chemical safety goggles. In case of skincontact with either chemical, flush with water.
