Detailed

Description :

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.

Main application:

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

· GRC and Concrete moulding

· PU resin casting

· General Mouldmaking

· Superior manual mold design

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
