When you see the “1:1” at the first sight, you might be confused. In fact, “1:1” refers to the mixing ratio of two parts of the silicone rubber. The two parts silicone rubber can be also called RTV-2 silicone. RTV-1 cures by the way of reacting with the moisture, while the RTV-2 by the way of mixing the two divided two component. As a result, the curing deepness of RTV-1 silicone is limited, while the RTV-2 silicone can cures from inside to outside at the same time, without the limits of thickness. This article is going to introduce 1:1 silicone for architectural restoration, and it may be helpful for you if you are interested in this field.
1:1 silicone for architectural restoration
1:1 silicone for architectural restoration is a kind of addition cure type molding silicone rubber. Perhaps some people know that the molding silicone rubber can make molds and duplicate some objects, such as resin gifts and plaster crafts, but they may still find it unbelievable to apply to architecture restoration. But as a matter a fact, a lot of architects tend to adopt 1:1 silicone to restore architectural parts. Form the outside people may think that the silicone rubber material is too weak to support the mold, though indeed it is, we can build a stable out shell surrounding the silicone mold. In some aspects, the 1:1 silicone has some irreplaceable merits. First of all, it can duplicate extremely intricate designs of the architectural parts. More than that, this kind of addition cure type molding silicone rubber can duplicate the architectural parts for many times. As is known to us all, there are often some architectural parts with similar designs, so we have to use the silicone mold for many times. The 1:1 silicone also has a good ability to resist high temperature(-60 degree centigrade to 200 degree centigrade) and aging.
