FEINGOSIL PA 340 (A+B) RTV-2 silicone rubber for jewellery
Feingosil PA 340 (A+B) is a pourable, bi-component RTV-2 silicone rubber vulcanizing at room-temperature with a poly-addition process without shrinkage. High mechanical properties and low viscosity give very flexible and resistant moulds and high details reproduction. It’s used to realize simple moulds without undercuts. It’s particularly suitable for the production of wax models, even by pressure injection, to realize jewellery.
