RTV-2 Addition silicone rubber for artificial stone molding

RTV-2 Addition silicone rubber for artificial stone molding description
Addition silicone rubber are generally named as two part addition silicone rubber that vulcanizes 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.

RTV-2 Addition silicone rubber for artificial stone molding rubber Main application:

· Rapid prototyping (urethane casting/silicone tooling/vacuum casting)

· GRC and Concrete molding

· PU resin casting

· General Mould making

· Superior manual mold design

RTV-2 Addition silicone rubber for artificial stone molding main properties:

· 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)

· Excellent non-stick effect

· Environmental, odorless and nontoxic
