Shelf Life Details Part A and Part B components of 3M Fire Barrier 2001 Silicone RTV Foam are delivered in separate containers. They should be stored out of the weather in their unopened containers at or below 90° °F (32° °C). When stored in the orignal unopened containers at this temperature, shelf life is 12 months from date of shipment from 3M. Patially used containers should be sealed tightly and stored in a similar manner. Shelf Life Type From date of shipment Shelf Life (mon) 12 -

Best Practices for 3M 2001
-
Surface Preparation
The penetration opening and all related surfaces must be clean of dirt, dust and loose impediments. Surfaces must also be free of water, oil or other free liquids.
-
Mixing
Prior to use, Part A and Part B components must be thoroughly stirred in their original containers to uniformly redisperse any fillers or pigments that may have settled. When mixing Part A and Part B, use clean containers and mixing equipment. If stirred containers stand for more than four hours, re-stir.
To properly catalyze 3M Fire Barrier 2001 Silicone RTV Foam, an equal quantity of Part A is added to an equal quantity of Part B by either weight or volume. For batch mixing by hand or power mix, vigorous and thorough mixing should be maintained for 30 to 60 seconds. The mixed product begins to foam shortly after mixing, therefore, it should be dispensed in the penetration as soon as mixing is completed. For large-volume applications, the use of suitable automatic mixing, metering and dispensing equipment is recommended. A list of equipment manufacturers is available from 3M upon request.
The type and degree of mixing can significantly affect the cell structure and density of the final foam product. Hand mixing will typically result in higher densities than power mixing by automatic mixing, metering and dispensing equipment. Typical expansion is 2:1 to 4:1 depending on the type and degree of mixing
-
Clean-Up
Excess foam around the penetration seal can be removed with a sharp knife or blade. Spills of Part A and Part B liquid components can be removed with high flash-point mineral spirit solvent. Follow manufacturers precautions when handling solvents.
