tin stab 4.5
stearic acid 1.2
however, we cant produce a clear film at lower temp. to be able to get a clear film, we process it 190C which leads us to burnt compound along the line later on so we have to stop and clean out the whole line! could you please suggest how we can improve the formulation so we could run at lower temp? thanks a lot in advance!

Len is correct ---ESO is best used with Ca/Zn or Ba/Zn stabilizers---and I would add that ESO should NOT be used with tin mercaptides, since I've seen ESO exude in presence of tin. If tin is your only choice for now, I'd suggest taking out the ESO.
