Rtv-2 silicon rubber for candle mould making

RTV silicone rubber for mold making 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.

RTV silicone rubber for mold making application :

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

for GRC and Concrete moulding

for plaster decoration duplication,

for gypsum sculpture reproduction,

for duplicating resin product with fine details,

for PU resin reproduction,

for wax molding,

for stone duplication ,

for epoxy moulds,

for pacrylic moulding,

for reproducing polyester craft

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.

RTV silicone rubber for mold making FAQ

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 .
