A two-component rubber of GUMOSIL®PC-12 type is a thixotropic agent changing the flowability of rubber composition of types: GUMOSIL®K, GUMOSIL®WW, GUMOSIL®M and GUMOSIL®S.
GUMOSIL®PC-12 is used in production of „over coated” forms made of silicone rubbers, giving the composition a highly illiquid character, which allows applying it with a paintbrush or spatula to obtain a thickness of approx. 10 mm and „removal” of forms from vertical models. Thixotropic agents reduce the shelf life of rubber significantly and therefore, in order to extend the „lifetime” of the rubber mass, the catalyst doze can be reduced. For most models, it is recommended to prepare such amount of the rubber with the thixotropic agent that can be applied within 10 – 15 minutes.
