PoolKemie SILIMOLD PX-30 RTV2 silicon moulding rubber
Categories: Polymer; Thermoset; Silicone; Silicone Rubber

Material Notes: Introduction: It is a two component room temperature vulcanizing hand moldable silicon which cures on the addition of the appropriate CATALYST PX-30, according to the polycondensation process. SILIMOLD PX-30 silicon rubber is characterized by a medium high hardness, an high dimensional stability and a good mechanical resistance.

Application: SILIMOLD PX-30 silicon rubber is ideal in the casting of any size of patterns and surfaces in vertical position. The flexible casts realized are characterized by an high mechanical strength, no discernable shrinkage and a good “sand ability”, in order to achieve a perfect finish.

Note 1: Tests have been carried out under these conditions: Temperature: +20°C; After: 24 ore; R.H.: 60%; Catalysis: 100:5
