RTV-504

 

RTV-521 is two parts mould making material (A :silicone,major component B: hardner). This product is room temperature cure , with high softness and excellent mobility, tensile strength , Tear resistance , etc.

 

Properties

low viscosity, easy to use ,low hardness, high strength ,suitable to used as packet mode material ,and mainly used to produce transparent poly-resin and elaborate artifact products ,with excellent performance .

Cure at room temperature , do not need insolation or extra heat

3. Good mechanical property , with high elasticity, softness, tensile strength and extensibility

4. Mainly used to produce Polyster , Epoxy products with moderate hardness, easy to demould , limited expansion ,high thermal stability ,the life span is longer than normal rubber .
