Room Temperature Vulcanizing (RTV) Silicone

 

 

Room temperature vulcanizing (RTV) silicone is constructed of reactive oil base polymers combined with strengthening mineral fillers. There are two types of Room temperature vulcanizing silicone:
• RTV-1
• RTV-2
RTV-1 (One-component systems)
RTV-1 hardens directly under the action of atmospheric humidity. The curing process begins on the outer surface and progresses through to its core. It is packed in airtight cartridges and is either in a fluid or paste form. RTV-1 silicone has good adhesion, elasticity and durability characteristics. The Shore A hardness can be varied between 18 and 60. Elongation at break can range from 150% up to 700%. They have excellent ageing resistance due to superior resistance to UV radiation and weathering. Industrial RTV-1 products are referred to as CAFs.

RTV-2 (Two-component systems)
RTV-2 elastomer are two-component products that, when mixed, cure at room temperature to a solid elastomer, a gel, or a flexible foam. RTV-2 remains flexible from -80°C to +250°C. Break down occurs at temperatures above 350°C leaving an inert silica deposit that is uninflammable and non-combustible. They can be used for electrical insulation due to their dielectric properties. Mechanical properties are satisfactory. RTV-2 is used to make flexible moulds, as well as many technical parts for industry and paramedical applications.
