RTV2 Silicone Rubber For Plaster Mould Making Gypsum Molding Liquid
Silicone Rubber
Description
RUI-HE 6250-30MJS® is a type of hard silicone with hardness Shore A
30. It is a kind of of two- component materials consisting of a
flowable part A which when mixed with the curing agent or
catalyst,cures at room temperature by a condensation recation. It
is widely used for making molds for artificial stone, gypsum
casting, grc, grfc, cement/concrete decorative products and etc.
