Reverse methyltin ester

Recommended reverse ester tin stabilizers include Thermolite 140, 172 butyltins and 174 methyltin Mark 1367 butyltin and 1939,1971,2903 methyltins Advastab TM-286SP and Interstab T-5201 and 5286. Substrate recipes may also include 0.15-0.25 phr of a lubricating processing aid. Addition of zeolite or hydrotalcite at a level of 0.5-1.0 phr will enable use of the low end of the above recommended usage and will provide for gradual rather than abrupt failure in case of factory misadventure. A suitable costabilizer for this purpose is Halstab 1214 coated zeolite.
