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.
RTV silicone rubber for mold making application :
· Rapid prototyping (urethane casting/silicone tooling/vacuum casting)
· GRC and Concrete moulding
· PU resin casting
· General Mouldmaking
· Superior manual mold design
RTV silicone rubber for mold making 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
RTV silicone rubber for mold making Storage
Sealing storage in the environment of dry, cool and ventilated. storage temperature should be kept during 0~40°C.
RTV silicone rubber for mold making Shelf-life
12 months under above conditions. It can be used after shelf life if the technical data is qualified.
FAQ of RTV-2 molding silicone rubbe
1. Why should the RTV-2 molding silicone rubbe mold be reused only for a few times?
It can be due to the following reasons:
a. Adding too much silicone oil in to silicon rubber.
b. Using the silicon rubber with a high hardness to make molds for small sized products with delicate and intricate designs .
