FEINGOSIL 5 AL/55-R RTV-2 poly-condensation silicone rubber

Feingosil 5 AL/55-R is a pourable bi-component RTV-2 silicone rubber vulcanizing at room temperature with a poly-condensation process. It gives a perfect replica of the original item. Highly resistant in all circumstances and thermo-stable. For its mechanical properties (high heat resistance/high hardness), it’s particularly suitable to protect electrical and electronic mechanical components with coating or filling (when it is necessary a rigid product or high thermal stability). It is also used to make copies of low melting alloys (lead or tin).
