Question from Li
Do you know anything about HeatnBond® Lite and HeatnBond® Hem for sewing? I sew a lot and sometimes my items call for fusible things and sometimes it would make my items a lot easier to make but I don’t want to use off gassing glues! Any help with this would be great Debra! Thanks! http://www.thermowebonline.com/c/our-brands_heatnbond
I got them to send me an MSDS for the product but don’t understand it. Would you help me decipher it? I can tell that I haven’t noticed much smell using it before. She said it is a hot melt adhesive.
Debra’s Answer
Thanks for sending the MSDS. That helps me a lot to answer your question.
OK. Under SECTION 2. PRODUCT AND COMPONENT HAZARD DATA it says “Components: Hydrocarbon and/or oxygen Hydrocarbon Polymers Approx. Percent: 99% TLV ** None **”
What does that mean? “TLV” stands for “threshold limit value” of a chemical substance, which is a level to which it is believed a worker can be exposed day after day for a working lifetime without adverse health effects. It’s an exposure limit.
Now what does “none” mean? I had to look this up and still the answer isn’t clear. The closest answer I could get was “a lower TLV means that less the allowed in the workplace air, and less you should inhale.”. So I’m thinking “none” means you shouldn’t inhale it at all. But that doesn’t make sense for this product. Yet, there are ***s around it so they want you to pay attention.
Then it says “see Section 6” which says:
Based on the above I would say that “none” means there is no need for concern.
