High Temperature Silicone for Jewelry Casting
High Temperature Silicone For Jewelry Casting Description :
Platinum Based Silicones For Jewelry Casting 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.
Platinum Based Silicones For Jewelry Casting Main application:
- Rapid prototyping (urethane casting/silicone tooling/vacuum casting)
- Concrete moulding
- PU resin casting
- General Mouldmaking
- Superior manual mold designs
- Cake/Chocolate molds
High Temperature Silicone For Jewelry Casting 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

Notice of High Temperature Silicone For Jewelry Casting
All above addition silicone is forbidden to mix with organic compounds of condensation cure silicone rubber,otherwise, the silicone rubber will not cure, and also should not mix with organic compounds containing S, P, N as well as metallic salt of organic acids. It also will cause this product cure uncompletely or not cure.
