RTV moulding silicone rubber for gypsum molds making description
RTV moulding silicone rubber for gypsum molds making 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 moulding silicone rubber for gypsum molds making 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 moulding silicone rubber for gypsum molds making 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
