| Single Component Spray Foam |
| Q | What is the R-value for the single component caulking foam? |
| A | The R-value for the single component foam is approximately 3.5 R per inch. |
| Q | What is the temperature limit? |
| A | For proper application, the foam should be applied between 55 – 90 F. Below 55F, the foam resin will become viscous and the rate of extrusion from the cylinders will be slow. For temperatures above 90F, the viscosity of the foam resin will decrease drastically. Extrusion rates from the cylinders will become too fast to be controlled comfortably. |
| Q | How do you solve the extreme temperature application problems? |
| A | We do have ‘Summer’ and ‘Winter’ formulations for the market. You may specify which formulation that you prefer when you order. |
| Q | How much does the foam expand after application? |
| A | The final expansion of the foam is directly proportional to the ambient temperatures. The higher the temperature, the higher will the final expansion be. In an ideal condition of 77F, 60% R.H., the average expansion of the cured foam is approximately 35%. |
| Q | Can I stop and reuse later? How long? |
| A | Yes, you may stop and reuse the partially emptied cylinder later. Shut off the flow of foam from the cylinder by turning the yellow color cylinder valve stem clockwise. Do not empty the foam resin from the hose. Insert a wire or nail about ½” into the tip of the brass nozzle. Store the cylinder indoor, away from direct sunlight, in a reasonable ambient condition. The foam resin in the hose must be purged and replaced with new foam resin weekly if you wish to store the foam cylinder for a prolonged period of time. |
| Q | How do I control the size of the foam bead during application? |
| A | For applications that require finesse, we recommend upgrading your application kit to our metering dispensing wand. You can control the size of the foam beads with this dispensing wand. |
| Q | My dispensing kit was clogged, but the foam resin in the cylinder is apparently fluid upon agitation and should be useable. What should I do? |
| A | You may order a new dispensing kit. This will include an 8 foot hose, ball-valve and brass dispensing nozzle. Remove the old hose from the cylinder. Clean the cylinder valve with solvent. Connect the new kit, and you are ready to go. |
| Two-Component Spray Foam |
| Q |
What is the R-value?
|
| A |
The R-value for the spray foam is approximately R7.2per inch.
|
| Q |
Can I spray inside the existing wall and attics?
|
| A |
Yes, you may spray into existing walls and attics. This is a common practice for residences in states with extreme cold or hot ambient conditions. The densely packed closed cells of this product are ideal for insulating against these extreme ambient conditions.
|
| Q |
What can I do if foam sagged before cured during vertical application?
|
| A |
You may have applied too much chemical on a vertical surface on one pass. Spray a thin coat on the surface. After the foam achieves full rise, apply a new coat. Building up the thickness of the foam this way will eliminate the sagging problem.
|
| Q |
What is the most efficient method to trim or shape cured foam?
|
| A |
The best tool to shape or mold cured foam is by using a long, serrated knife. Using a back and forth motion, you will be able to trim the cured foam to any shape that you prefer. If you wish to obtain further refining of the shapes of your cured foam, you may use a hand sander or Dramel tool to add final contours.
|
| Q | What is the optimum temperature for applications? |
| A | Spray foam should be applied between 650 F through 900F. For ambient temperatures below 650F, the reaction profiles will be slowed down. The curing time will be increased. User should store the foam unit indoor for at least 24 hours to allow the resins to achieve at least minimum performing internal temperatures. If spray application is performed for temperatures above 900F, the blowing agents in the formulation will expand and evaporate too fast before the foam is properly cured. Slight shrinkage will occur. |
| Q | If I have significant amount of chemicals left after I finished my job, can I re-use the kit months later? |
| A | Yes, of course you can. Turn the yellow valves on both Resin-A and Resin-B off by turning them counter-clockwise. Follow the procedures in the application manual to properly prepare the spray foam kit for storage. If the spray gun is clogged due to extreme ambient conditions during storage, you may order a replacement gun kit from your distribution or directly from the factory. |
| Q | What should I do if I have a confined space that I do not want to over-stuff the cavity with foam? |
| A | You may order our new, slow-rise formulation. The foam will rise slowly to offer the user more control on how much foam he can apply. This formulation is only for cavity filling. When used on a vertical surface, foam with this formulation will sag or drop off due to its slow reaction profiles. |
| Q | Does the spray foam kit contain any flammable fluids? |
| A | Our spray foam kits do not contain flammable fluids. Our blowing agents in the formulation are also ozone friendly. |
