molding silicone for resin crafts mold making

Moulding Silicone 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.

Moulding Silicone application :

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

· GRC and Concrete moulding

· PU resin casting

· General Mouldmaking

· Superior manual mold design

Moulding Silicone 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

Molding silicone Storage

Sealing storage in the environment of dry, cool and ventilated. storage temperature should be kept during 0~40°C.

Moulding Silicone Shelf-life

12 months under above conditions. It can be used after shelf life if the technical data is qualified.
