PoolKemie SILIMOLD BVL-22 RTV2 silicon moulding rubber - Low viscosity
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber
Material Notes:	Introduction: It is a two component room temperature vulcanizing pourable fluid silicon which cures on the addition of the appropriate CATALYST B*, according to the polycondensation process. A highly anti-adherent flexible compound, that is extremely accurate in its reproduction of fine details. Application: SILIMOLD BVL-22 silicon rubber is ideal in the manufacture of moulds for the shoe industry (production of master moulds for rubber soles), technical items in general, and decorative plaster subjects like ceiling roses, frames, and wherever the reproduction of undercuts is not requested, due to its moderate tearing resistance. Note 1: Tests have been carried out under these conditions: Temperature: +20°C; After: 24 ore; R.H.: 60%; Catalysis: 100:5 Information provided by Poolkemie
