Addition silicone rubber for PU resin casting, rapid prototying, general mold making and so on.

Detailed

Addition silicone rubber for PU resin casting

Addition silicone rubber for PU resin casting is generally named as twopart 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.

Addition silicone rubber for PU resin casting 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
