Special care must be taken when shipping, handling and storing Simalfa to insure it is not exposed to freezing temperatures.
Starting October 15th of each year and continuing throughout winter until April 15th we include with each shipment a Freeze Watch that is placed inside the packing envelope as a guide to determine if the shipment was exposed to freezing temperatures.
When the Freeze Watch is exposed to freezing temperatures, the liquid in the ampule will solidify, causing it to fracture. As thawing occurs, the white background paper behind the ampule will become irreversibly stained by the liquid. This indicates that the shipment was subjected to freezing temperatures.
Upon delivery of SIMALFA - inspect the Freeze Watch to see if it was frozen. If SIMALFA has been exposed to freezing temperatures the indicator paper will be stained with color. If indicator paper shows no color indication, remove indicator from package. Vigorously tap bottom edge of indicator, three times, on a hard surface. If paper becomes stained after tapping, SIMALFA was exposed to freezing temperatures. Tapping will not cause color staining in an unexposed indicator.
The Freeze Watch should be in an area above freezing for at least 15 minutes to insure an accurate reading if stored and/or transported in extremely cold temperatures.
No, not necessarily! The Freeze Watch will freeze long before the adhesive. It simply indicates further inspection is needed before use.
You must insist your shipment be protected from freezing. This type of protection varies among freight carriers, so we recommend climate-controlled trailers and not trailers where heaters are placed near material. We further recommend that the carrier clearly understands they are liable for frozen and/or damaged product. Our policy is not to ship via non-heated trailers during periods of possible freezing.
There are a number of things we do such as package design, clearly marking the bill-of-lading "Do Not Freeze", and educating the freight carrier as to the importance of freeze protection.
