Polycondensation silicone

Main category >Silicones >Polycondensation silicone

The biggest advantage of polycondensation silicones is their prevalence and relatively lower price, but they shrink by about 0.2 - 2% due to the precipitation of alcohols during hardening, crosslinking problems can be caused by too low ambient moisture content (eg gypsum, etc.), contains silicone oil , this may make the subsequent painting of the products more difficult, the tin catalyst is toxic, the polyester casting resins destroy the polycondensation silicone quickly. Mixing ratio is usually 100: 3-5 which is difficult to measure and mix properly in small quantities… Compared to similar competing silicones available in Hungary, Zhermack's polycondensation silicones still have a higher elongation at break and only 0.5% shrinkage!
