RTV-2 silicones consist of two components. When carefully mixed, they crosslink at room temperature to form an elastic silicone rubber. They can be manually processed because of their very low viscosity in many cases. When processing large quantities, we recommend using automatic mixing and metering equipment.
For RTV-2 silicones, there are two types of chemical crosslinking:addition curing and condensation cross-linking
RTV-2 silicones that are premixed during production are designated as 1K heat-curing systems and exceptionally well-suited for use as impermeable elastic adhesive sealants. However, the crosslinking must occur at a temperature of at least 120 °C.
Other unique products are the silicone gels such as Wacker SilGel® 612. Silicone gels are extremely sticky and so soft when crosslinked that the Shore scale cannot be used to determine hardness. The softness is therefore designated by specifying the penetration of a cone.
The product portfolio's wide range of RTV-2 silicone rubber types provides an optimum basis for the production of vulcanizates with various highly specialized properties. This provides a versatile, competitive portfolio of solutions to individual problems in all key industries such as moldmaking, mechanical engineering and industrial plant construction, in electronics and optoelectronics, household appliances, health care as well as solar and photovoltaics.
