    If it's yellow and 3M, it's UL-tested:

    It's not safe to assume that because a firestop caulk is red, it has been UL-tested for your applications. 3M offers the yellow firestop caulk that has been UL-tested to ASTM E 814 for the most common applications.

    3M Fire Barrier IC 15WB Caulk is an affordable firestop caulk that helps you stay on budget. Our distinctive yellow firestop caulk makes inspections easier. Plus, our fire barrier sealant provides protection around typical pipe and cable penetrations through fire-rated construction.

    Asked by Anonymous user on 11.08 AM Tuesday, 07 March, 2017

    Answer:
    • - Hello, The 3M Fire Barrier IC 15WB Sealant has a continuous operating temperature of 120F (48C)so as long as the area that you are sealing does not exceed this temperature, then this will be a great product. However, if the area that you are sealing has a continuous operation temperature above that, we do offer other products with a higher temperature rating. Please give us a call at 866-222-0030 and we can discuss those other options and find the one that will best work for your application. Thank you,
