Poolkemie SILIMOLD AL 40

Poolkemie SILIMOLD AL 40 is a two component room temperature vulcanising pour able fluid silicon which cures on the addition of the appropriate CATALYST S o SN, according to the polycondensation process. SILIMOLD AL-40 silicon rubber is characterized by its medium-high hardness, an high dimensional stability and a good mechanical resistance. Thanks to these properties, it may also be utilized in the manufacture of molds for the reproduction of large sized patterns.
