RTV-2 silicon rubber for gypsum molds
1.Description of RTV-2 silicon rubber for gypsum molds :
RTV mold making addition silicone are generally named as two-part addition silicone rubber that vulcanises at room temperature.Part A is a flowable liquid, part B is the curing agent(platinum catalyst). It features an exceptional fluidity ,good operability,excellent physical properties and very low shrinkage.
The mixing ratio between Part A and Part B can be 10:1 or 1:1.
2.Main application of RTV-2 silicon rubber for gypsum molds :
· GRC and Concrete moulding
· PU resin casting
· General Mouldmaking
· Superior manual mold design
3.Main properties of RTV-2 silicon rubber for gypsum molds :
· almost nil shrinkage
· high chemical resistance to aggressive components of some types of resins
· good tear strength (this feature ensures higher resistance to wearing and shearing)
· high degree of precision in reproduction
· high dimensional stability over time and non-deformability
· high resistance to high temperatures and ageing (resit to -60-200°C)
· environmental, odorless and nontoxic
