The United States Department of Transportation has a new shipping classification for the Versi-Foam low-pressure spray polyurethane foam systems. The prior product description fell under: UN1956 Compressed Gas, N.O.S. (Fluorinated Hydrocarbon, Nitrogen). The new product classification for shipping by all modes of transportation (road, air, and vessel) will be as follows: UN3500 Chemical Under Pressure, N.O.S. (Fluorinated Hydrocarbon, Nitrogen).
It’s that time of year again – when cooler temperatures can affect the performance of your Versi-Foam® System. To ensure the peak performance of your Versi-Foam® System and quality foam production, here are a few helpful tips:
Never store Versi-Foam® products in temperatures lower than 40°F (5°C). Storing at these temperatures may cause the chemicals to freeze. If the “A” component freezes, it will crystallize, creating blockages in the dispenser. Once this occurs, it cannot be fixed.
Always warm the chemicals to a temperature between 65°F to 90°F(18°C to 32°C) before using. Refer to the temperature sensing strip to be sure it is well within the green zone. During application, continue to monitor the temperature strip. If it begins to move toward the blue zone, warm the chemicals again. Cooler chemicals will result in foam that is “A” rich, which will be darker in color and have a crunchy surface.
Bring your Versi-Foam kits into a warm/conditioned space for at least 24 hours prior to using. After warming the chemicals, be sure to shake the tanks well to ensure a uniform temperature throughout.
Always warm the surface onto which you are applying the foam to a temperature between 65°F to 90°F (18°C to 32°C). Colder surface temperatures may result in adhesion problems and reduced yields. For answers to more questions, visit our support page.
